Making Mining Work for Zambia: Economic, Health, & Environmental Nexus of the Copper Mining Economy
Zambia's rich mineral resources are one of the country's most important assets. They contribute to national income, exports, employment and government revenue. As the country looks to the future, Zambia faces important choices on how to manage its mineral wealth. There are trade-offs in the design of the mining fiscal regime. Mining inevitably entails environmental and public health risks. Mining firms make choices about procurement that influences the industry's contribution to the Zambian economy. This brief video introduces the World Bank's Fifth Zambia Economic Brief "Making Mining Work for Zambia: The Economic, Health, and Environmental Nexus of Zambia's Copper Mining Economy," which was released in June 2015. It asks how Zambia can uses its mineral resources to help the country achieve its economic development ambitions. The report suggests areas where the government, business community, and civil society can collaborate to enhance the contribution of mining to Zambia.

Lead Exposure Risks in the Work Environment
The National Institute for Occupational Safety and Health (NIOSH) reports that while many people worry about lead in their homes or in the environment, for some the workplace may offer the greatest potential for exposure. Lead is a toxic heavy metal. It can be combined with other metals to produce alloys. Lead and lead alloys are often used to make batteries, ammunition and other metal products. In the past, lead was also used regularly in fuel, paint, ceramics, caulk, pipes and solder among other things. Due to potential health issues from exposure, the amount of lead used in these products today has lessened or has been removed. Though used less often, NIOSH reports that lead is still common in many industries, including construction, mining and manufacturing. In these and other industries, workers can be at risk of being exposed to lead, by breathing it, ingesting it or coming in contact with it. NIOSH provides the following information for workers about how lead exposure can occur: • Workers can be exposed by breathing-in lead fumes or lead dust. Lead fumes are produced during metal processing, when metal is being heated or soldered. Lead dust is produced when metal is being cut or when lead paint is sanded or removed. Lead fumes and lead dust do not have an odor, so workers may not know they are being exposed. • Lead dust can settle on food, water, clothes and other objects. If a worker eats, drinks or smokes in areas where lead is being processed or stored, they could ingest it. Not washing one’s hands before eating or touching one’s mouth are also ways it could be ingested. • Workers can also be exposed by coming into contact with lead dust. Some studies have found lead can be absorbed through skin. Workers that handle lead and then touch their eyes, nose or mouth, could be exposed. Lead dust can also get on clothes and hair. If this happens, it’s possible that a worker could track home some of the lead dust, which may also expose their family. These are just a few things to know about lead exposure risks in the work environment.

Hazards Around Bins And Hoppers 1978 Mine Safety & Health Administration
more at http://quickfound.net "Emphasizes the safety of those who must work around bins and hoppers and acquaints them with the potential hazards of entering these and other material storage areas. Encourages workers to follow the safe and correct operating procedures that apply to their jobs." Public domain film from the US National Archives, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied. The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original). http://creativecommons.org/licenses/by-sa/3.0/ https://en.wikipedia.org/wiki/Mining#Safety Safety has long been a concern in the mining business especially in sub-surface mining. The Courrières mine disaster, Europe's worst mining accident, involved the death of 1,099 miners in Northern France on March 10, 1906. This disaster was surpassed only by the Benxihu Colliery accident in China on April 26, 1942, which killed 1,549 miners. While mining today is substantially safer than it was in previous decades, mining accidents still occur. Government figures indicate that 5,000 Chinese miners die in accidents each year, while other reports have suggested a figure as high as 20,000. Mining accidents continue worldwide, including accidents causing dozens of fatalities at a time such as the 2007 Ulyanovskaya Mine disaster in Russia, the 2009 Heilongjiang mine explosion in China, and the 2010 Upper Big Branch Mine disaster in the United States. Mining ventilation is a significant safety concern for many miners. Poor ventilation inside sub-surface mines causes exposure to harmful gases, heat, and dust, which can cause illness, injury, and death. The concentration of methane and other airborne contaminants underground can generally be controlled by dilution (ventilation), capture before entering the host air stream (methane drainage), or isolation (seals and stoppings). Rock dusts, including coal dust and silicon dust, can cause long-term lung problems including silicosis, asbestosis, and pneumoconiosis (also known as miners lung or black lung disease). A ventilation system is set up to force a stream of air through the working areas of the mine. The air circulation necessary for effective ventilation of a mine is generated by one or more large mine fans, usually located above ground. Air flows in one direction only, making circuits through the mine such that each main work area constantly receives a supply of fresh air. Watering down in coal mines also helps to keep dust levels down: by spraying the machine with water and filtering the dust-laden water with a scrubber fan, miners can successfully trap the dust. Gases in mines can poison the workers or displace the oxygen in the mine, causing asphyxiation... Ignited methane gas is a common source of explosions in coal mines... Miners utilize equipment strong enough to break through extremely hard layers of the Earth's crust. This equipment, combined with the closed work space in which underground miners work, can cause hearing loss... Since mining entails removing dirt and rock from its natural location, thereby creating large empty pits, rooms, and tunnels, cave-ins as well as ground and rock falls are a major concern within mines. Modern techniques for timbering and bracing walls and ceilings within sub-surface mines have reduced the number of fatalities due to cave-ins, but ground falls continue to represent up to 50% of mining fatalities. Even in cases where mine collapses are not instantly fatal, they can trap mine workers deep underground. Cases such as these often lead to high-profile rescue efforts, such as when 33 Chilean miners were trapped deep underground for 69 days in 2010. High temperatures and humidity may result in heat-related illnesses, including heat stroke, which can be fatal. The presence of heavy equipment in confined spaces also poses a risk to miners. To improve the safety of mine workers, modern mines use automation and remote operation including, for example, such equipment as automated loaders and remotely operated rockbreakers. However, despite modern improvements to safety practices, mining remains a dangerous occupation throughout the world...

Hazards of Lead
Although less common than it used to be, lead exposure still occurs at work. This toxic metal can be found in a variety of industries, including construction, mining and manufacturing, according to NIOSH. The agency stresses that it is important for workers to understand how exposure to lead occurs so it can be avoided. Ways workers can be exposed include: Breathing in lead dust or fumes: Lead dust is created when metal is cut or lead paint is sanded. Lead fumes occur during metal processing. Consuming lead dust: Because lead dust can settle on food, clothes and other items, if you eat or drink in areas where lead is processed or stored, you can ingest lead. Coming in contact with lead dust: Workers can come in direct contact with lead dust via the eyes, nose, mouth or skin. Additionally, as lead dust can settle on clothes, workers may expose their families by tracking home lead dust. Short-term exposure to high levels of lead can cause abdominal pain, headaches, irritability, memory problems and loss of appetite. These symptoms often are overlooked because they tend to occur slowly over time, according to NIOSH. More serious health consequences of exposure to high levels of lead include kidney and brain damage, and even death. NIOSH offers numerous tips to help prevent lead exposure on the job. These include refraining from eating or drinking where lead-containing items are processed or stored, using a lead removal product to clean your hands, showering and changing your clothes and shoes before leaving work if you work in an environment that contains lead, and working in well-ventilated areas. Are you concerned that you may have been exposed to lead on the job? NIOSH recommends talking with your employer to see if routine BLL testing – a simple blood test that can measure your blood-lead levels – is conducted. If your employer does not conduct this testing, consult with your medical provider about having the test done, NIOSH states.

Most Toxic Substances On Earth
Deadly toxins could be lurking in the places you would least expect them to. In small doses, some of these substances we’re about to mention are beneficial to mankind. However after years of exposure or getting splashed water from your own home aquarium could me enough to have life changing consequences. Other chemicals are engineered by scientists in laboratories to create as much destruction as possible. Some questionable things put into the foods we eat every day, to pollutants that are known to cause cancer, here are the most toxic substances on earth! 14. Hexavalent Chromium Hexavalent chromium is an oxidized form of the element chromium in the +6 oxidation state which is recognized as a human carcinogen. It’s more often than not found in industrial areas especially in tanneries in Hazaribagh, Bangladesh which can emit 21,600 cubic meters of toxic each day into the environment. It can also be found in textile dyes, wood preservation, anti corrosive agents to paint, and other surface coatings. It can also be formed from heating up or welding stainless steel or melting chromium. 13. Brominated Vegetable Oil In what case do you think bromite might be acceptable in your diet? Just about never?! Also konwn as BVO, it’s banned just about everywhere in the world as a food additive but it still in active use in the US and japan. Why would they add a strange substance in our drinks? It’s mainly to keep different flavors and ingredients from breaking apart and helps prevent certain flavors from floating up to the top. It might end up in your soft drinks like mountain dew, fanta sundrop and energy drinks. Despite pepsi cola and coca cola vowing to remove it from their soft drinks, it can still be seen in their ingredients. Brominated Vegetable oil might also be used as a pesticide, flame retardant, in nasal spray and plastics to name a few. It’s also linked to thyroid problems, skin rashes and other bad stuff. Check for this sneaky ingredient next time your shopping and let us know where you find it in the comment section 12. Lead HIgh levels of lead exposure can lead to fatality while lead build up in the body over a long period of time can have frightening and painful results. The city of Picher oklahoma became highly contaminated with lead which gave many a closer look of the symptoms. Teachers would report severe learning disabilities here and for a while no one was sure why but it definitely wasn’t from attention deficit disorder! It became evident that the tap water became mixed with lead that was being mined in the town. Sources of exposure can be from the following: soil, household dust, pottery, toys, paint chips, cosmetics, mexican candy, lead bullets, and mining. Many recalls have taken place from China because it was discovered that lead with paint was being used on toys such as hot wheels. 11. STevia You might see a drink that’s labelled as having natural flavoring but you might fully understand until you read the ingredients. A new sweetener is found in various coca cola products that is found in a plant, but, it can be processed to be 200 times sweeter than natural sugar without adding calories. The process used to create this extraordinarily sweet food is anything but natural, using chemicals such as ethanol, isopropanol and other complicated chemicals. You can see it labeled on this bottle as stevia extract If it’s so natural, why did coca cola want to patent their process of extracting the stevia sweetener from the plant?. Some studies would insist that something this sweet can cause the body to act in a similar way as if it were consuming something with actual sugar. 10. Silver There’s more than one reason you don’t wanna get a silver metal if you’re competing in the olympics. While silver might not be hazardous to the touch, ingesting silver orally can lead to bizarre complications.The condition, known as argyria is often caused from high amounts of chemical compounds from the element of silver or silver dust making their skin silver-like in the process. It can also turn the skin blue or a blue-ish grey. 92 year old man has a generalized form of argylia and you can tell how these chemical compounds have tragically affected him. It’s visible over large surfaces of the body but people with this condition can also appear to be physically in good shape despite their strange skin color. Stan Jones, a Libertarian candidate for US senate, ingested large amounts of silver thinking it had some type of home remedy with healing power. Strange but true.

Picher, Oklahoma, abandoned town, EPA superfund site, sinkholes - from a drone's perspective
Picher is a ghost town and former city in Ottawa County, Oklahoma, United States. This was a major national center of lead and zinc mining at the heart of the Tri-State Mining District. More than a century of unrestricted subsurface excavation dangerously undermined most of Picher's town buildings and left giant piles of toxic metal-contaminated mine tailings (known as chat) heaped throughout the area. The discovery of the cave-in risks, groundwater contamination, and health effects associated with the chat piles and subsurface shafts resulted in the site being included in 1980 in the Tar Creek Superfund Site by the US Environmental Protection Agency. The state collaborated on mitigation and remediation measures, but a 1996 study found that 34% of the children in Picher suffered from lead poisoning due to these environmental effects, which could result in lifelong neurological problems.[4] Eventually the EPA and the state of Oklahoma agreed to a mandatory evacuation and buyout of the entire township. The similarly contaminated satellite towns of Treece, Kansas and Cardin, Oklahoma were included in the Tar Creek Superfund site. A 2006 Army Corps of Engineers study showed 86% of Picher's buildings (including the town school) were badly undermined and subject to collapse at any time.[5] The destruction of 150 homes by an EF4 tornado in May 2008 accelerated the exodus. On September 1, 2009, the state of Oklahoma officially dis-incorporated the city of Picher, which ceased official operations on that day. The population plummeted from 1,640 at the 2000 census to 20 at the 2010 census. As of January 2011, only six homes and one business remain, their owners having refused to leave at any price. Except for some historic structures, the rest of the town's buildings were scheduled to be demolished by the end of the year. One of the last buildings, which had housed the former Picher mining museum was destroyed by arson in April 2015. Fortunately, its historical archives and artifacts had previously been shipped elsewhere. Picher is among a small number of locations in the world (such as Gilman, Colorado, Centralia, Pennsylvania, and Wittenoom, Western Australia) to be evacuated and declared uninhabitable due to environmental and health damage caused by the mines the town once serviced.

Iridium - The MOST RARE Metal on Earth!
Chemical Elements: http://www.ebay.com /usr/novaelementscom?_trksid=p2047675.l2559 NOVAELEMENTS: https://www.novaelements.com/ Mel Science chemical sets: https://goo.gl/SxwFlQ Patreon: https://www.patreon.com/Thoisoi?ty=h Facebook: https://www.facebook.com/thoisoi2 Interesting page about chemical experiments: http://m.chemicum.com/ Instagram: https://www.instagram.com/thoisoi/ So today I will tell you about the most rare metal on Earth - iridium. Iridium is a transitional metal, which is located in the middle of the periodic table, below rhodium. If we take a look at the prevalence of all elements in the earth's crust, Iridium holds the last place, that is a billion atoms of all that there is and only one atom of iridium. This metal is 40 times rarer than gold. In much higher concentrations iridium is found in meteorites and also in the depths of the Earth, in magma. Interestingly enough, in the layers of rock sediments, though more precisely in the formation of clay, that is aged about 66 million years there were found high concentrations of iridium and this can indicate the collision of Earth with a huge meteorite in the past, which in theory was the cause of the death of the dinosaurs. In it’s appearance iridium is a shiny metal that does not oxidize in air. This metal has almost the highest density of all metals, just 0.12% lower than that of osmium - the most dense metal. In this tiny tiny metal droplet, which is of the size of a match head, we have 1 gram of iridium. To help you understand how high is the density of iridium, I will show other metals with the same mass for comparison. Lead, copper, gallium, zinc, magnesium, and the lightest metal - lithium. The volumes of the first and last metal differ by about 30 times, although their mass is the same. Iridium is also a very hard metal that is firmer than the solid steel in 1.5 (one and a half) times. Iridium, in addition to its rarity is even the most stable metal that does not oxidize in air up to 2000 degrees, and is not soluble in either acid or aqua regia. Iridium can only react with the fluorine at temperatures of about 600 degrees. Unfortunately, due to the low activity of iridium, I cannot conduct any chemical experiments or have quality reactions with it. The only thing that I can do is make a fine powder of iridium and set it on fire in the air, but as you can see, in this case iridium dust is burning quite slowly and also requires dispersing it in the air. For the first time on youtube, you can observe a burning iridium. Also, due to the low activity of iridium, the metal does not tarnish in air, even when heated to above 1,000 degrees. The only thing that the drop of iridium got covered with is a partially evaporated ceramic layer, the one that the forceps are made from. Iridium compounds are can be either brown or yellow, such as the complex of Vasca, which is used as a catalyst in organic chemistry. By the way, Iridium is the only element that can give away 9 electrons and form compounds with +9 (plus nine) oxidation state. Iridium now finds many uses in science and technology. In most cases, we will probably find iridium in spark plugs for vehicles, due to the high stability of iridium to oxidation under the influence of electric discharge. Pure iridium is used for making crucibles for growing single crystals, foil for making non-amalgam cathodes, as well as as a part of the highly resistant to corrosion alloys. The first standard of mass of one kilogram was created in 1889 using an alloy composition of 90% platinum and 10% iridium and is called the International Prototype Kilogram, it is still kept in the Paris Chamber of Weights and Measures. Now you know more about one more of the elements, if you would like the scientific series of the elements to continue, please subscribe to my channel and also throw in some likes if you can!

Lead Ore Milling 1934 US Bureau of Mines
Nestled deep within the eastern Ozarks is an area known as the Old Lead Belt; it is a major part of the great Southeast Missouri lead district, the premier lead mining district of the world. The mining industry in this area has played an important role in Missouri's economic and social fabric for more than 280 years. St. Joseph Lead Co. is one of the major corporate enterprises that came to Missouri to mine lead. Lead and zinc production involved crushing and grinding the mined rock to standard sizes and separating the ore. This left behind piles of leftover rock called tailings that covered 4,000 acres in southeastern Cherokee County. These wastes were also a source of contamination. Lead, zinc, and cadmium from the tailings leached into the shallow ground water, contaminating local wells, and runoff moved contaminants into nearby streams and rivers. Wind also blew fine metal-bearing dust (from tailings piles and roads made of tailings) into the air, spreading the contamination to nearby non-mined areas. Radon gas from the mining operations was detected in the air around Galena. During the 1980's, this area was considered one of the most environmentally blighted in the nation. Some of the cleanup efforts are funded by the U.S. Environmental Protection Agency's Superfund. The EPA began working in the area in the early 1980's and work is ongoing. The EPA divided the Cherokee County Site into six subsites that correspond to six general mining locations, including the areas around Galena, Baxter Springs, and Treece, Kansas. Because the area in and around Galena had some of the worst contamination, early cleanup efforts were centered there. Chief among these was the provision of safe water supply for rural residents whose wells had been contaminated. Two new wells were constructed in the deep aquifer, and a new rural water district was formed that currently provides over 500 households with a long-term source of clean drinking water. From 1997 to 1999, contaminated soil was removed from 602 residential properties in Galena and replaced with clean backfill and grass sod or seed; fifty additional properties were remediated in 2000 and 2001. Remediation of residential soils has been completed in Treece and is ongoing in Baxter Springs. Cleanup continues at other sites in southeastern Kansas. For more information, check the EPA Region 7's website: http://www.epa.gov/region07/index.html . It does not matter if a person breathes in, swallows, or absorbs lead particles, the health effects are the same; however, the body absorbs higher levels of lead when it is breathed in. Within our bodies, lead is absorbed and stored in our bones, blood, and tissues. It does not stay there permanently, rather it is stored there as a source of continual internal exposure. Lead poisoning can happen if a person is exposed to very high levels of lead over a short period of time. When this happens, a person may feel: Abdominal pain, Constipated, Excessively tired, Headache, Irritable, Loss of appetite, Memory loss, Pain or tingling in the hands and/or feet and Weak. Because these symptoms may occur slowly or may be caused by other things, lead poisoning can be easily overlooked as their cause. Being exposed to high levels of lead may cause anemia, weakness, and kidney and brain damage. Very high lead exposure can cause death. A person who is exposed to lead over time may feel: Abdominal pain, Constipated, Depressed, Distracted, Forgetful, Irritable, Nauseous/Sick. People with prolonged exposure to lead may also be at risk for high blood pressure, heart disease, kidney disease, and reduced fertility. The Department of Health and Human Services (DHHS), Environmental Protection Agency (EPA), and the International Agency for Research on Cancer (IARC) have determined that lead is probably cancer-causing in humans. This clip is from the 1934 US Bureau of Mines film (made in cooperation with the St. Joseph Lead Company), THE STORY OF LEAD MINING AND MILLING. The entire film shows mining and milling operations in Southeast Missouri after diamond drills have located a lead vein. The film also shows the dairy, school, hospital, and offices of the St. Joseph Lead Company. The entire film is available at the US National Archives in Maryland.

Westward Expansion: Crash Course US History #24
In which John Green teaches you about the Wild, Wild, West, which as it turns out, wasn't as wild as it seemed in the movies. When we think of the western expansion of the United States in the 19th century, we're conditioned to imagine the loner. The self-reliant, unattached cowpoke roaming the prairie in search of wandering calves, or the half-addled prospector who has broken from reality thanks to the solitude of his single-minded quest for gold dust. While there may be a grain of truth to these classic Hollywood stereotypes, it isn't a very big grain of truth. Many of the pioneers who settled the west were family groups. Many were immigrants. Many were major corporations. The big losers in the westward migration were Native Americans, who were killed or moved onto reservations. Not cool, American pioneers. Support CrashCourse on Patreon: https://www.patreon.com/crashcourse Hey teachers and students - Check out CommonLit's free collection of reading passages and curriculum resources to learn more about the events of this episode. America’s Westward expansion was fueled by both Manifest Destiny and a desire to grow the nation and its resources — though at a cost: https://www.commonlit.org/texts/manifest-destiny As Americans continued to stream West on the name of Manifest Destiny, American Indians saw their lives changed forever as they moved from practising resistance to lives on reservations: https://www.commonlit.org/texts/from-resistance-to-reservations

Sulfur Dioxide & Exposure Concerns
Sulfur dioxide (SO2) is one of a group of highly reactive gasses known as oxides of sulfur. It is a colorless gas with a pungent and suffocating odor. It is a common air pollutant found in many parts of the world. Much of the sulfur dioxide in the air comes from the burning of coal and oil at electric power plants. Other sources of sulfur dioxide come from industrial facilities that use coal or oil, petroleum refineries, cement manufacturing, metal mining and processing, paper pulp manufacturing and copper smelting. Trains, large ships and some diesel equipment may burn high sulfur fuels which also contributes to sulfur dioxide in the air. Sulfur dioxide has also been used as a food preservative and for food processing; as a disinfectant; for bleaching flour, fruit, grain, wood pulp, wool, textile fibers, wicker, gelatin and glue; and for making other chemicals. It is also used for wastewater treatment. Sulfur dioxide and nitrogen oxides can react with precipitation, oxygen and other substances in the atmosphere to form acid rain. People can be exposed to sulfur dioxide outdoors by breathing polluted air. This is more likely to occur in the summer, when the sun and hot temperatures react with pollution to form smog. Natural pollution sources, such as plant decay and volcanoes can also expose people to this gas. People who live near or work in facilities that utilize sulfur dioxide or produce it as a by-product may also be exposed. According to the U.S. National Library of Medicine, “Breathing sulfur dioxide can irritate the nose, throat, and lungs, and cause coughing and shortness of breath. Short-term exposure to sulfur dioxide can cause stomach pain, menstrual disorders, watery eyes, inhibition of thyroid function, loss of smell, headache, nausea, vomiting, fever, convulsions, and dizziness.” They also report, “Short-term exposure to high levels of sulfur dioxide in the air can be life-threatening by causing breathing difficulties and obstructing airways, especially for people with lung disease. Long-term exposure to persistent levels of sulfur dioxide can cause chronic bronchitis, emphysema, and respiratory illness. It can also aggravate existing heart disease.” These are just a few things to know about sulfur dioxide, exposure risks and potential health concerns.

Protection Against Radioactivity in Uranium Mines 1969 US Bureau of Mines
This film from the United States Bureau of Mines presents general descriptions of the hazards of radon daughters in uranium mines, and outlines the environmental control, principles and procedures for mitigating the hazard. Scenes of underground mines show the origin and reason of the hazard, and various methods of ventilation are shown on how to correct the condition. Uranium mining occurred mostly in the southwestern United States and drew many Native Americans and others into work in the mines and mills. Despite a long and well-developed understanding, based on the European experience earlier in the century, that uranium mining led to high rates of lung cancer, few protections were provided by employers or government for US miners before 1962 and their adoption after that time was slow and incomplete. Some US officials and scientists advocated ventilation requirements in US mines as a proactive, preventative measure during the 1950s, on the basis of their knowledge of European experience. Duncan Holaday, an industrial hygienist with the PHS, has generally been recognized as the most prominent advocate for ventilation. He led the effort to obtain measurements of radon in the mines, and he used the data to argue forcefully within the government that ventilation would be effective and was feasible. His arguments achieved only limited success, as there was government resistance to requiring ventilation and his views were not made public at the time. The Atomic Energy Commission (AEC) was an obstacle. In the late 1940s, controversy erupted in the New York Operations Office over the hazards from beryllium and uranium mining. The AEC wrote worker health requirements in contracts with companies that handled beryllium. After conflicting recommendations from staff, it chose not to establish such requirements for uranium. It claimed to lack legal authority, but it did not explain the legal difference between uranium and beryllium. The AEC did not lack knowledge: records of a January 25, 1951, internal meeting of AEC and PHS staff reveal that, on the basis of early measurements, they believed that radon was present in levels that would cause cancer and that ventilation could abate the hazard. Public acknowledgment of this problem was apparently squelched. For instance, Hueper, the scientist who wrote the 1942 review and who was then at the National Cancer Institute, was forbidden to speak in public about his concerns about the health hazard of radon in uranium mines. It is reported that he was even forbidden to travel west of the Mississippi, lest he say too much to the wrong people. The resulting high rates of illness among miners led in 1990 to passage of the Radiation Exposure Compensation Act. For more details, see the outstanding article, The History of Uranium Mining and the Navajo People, in the Sept 2002 American Journal of Public Health at http://www.ajph.org/cgi/reprint/92/9/1410 .

Put Himalayan Salt Lamp In Your Bedroom And This Will Happen
You don’t know what you’re missing if you’ve never owned a Himalayan salt lamp. It’s like having an open window – a softly glowing natural source of fresh, clean air – on your desk, in your living room, next to the bed, or anywhere you choose to put it. Himalayan salt lamps are made from pure, food grade, Himalayan salt crystals and can even be powdered to use as salt in recipes if needed. These beautiful lamps have gained massive popularity recently and there are many benefits attributed to them. Here are some of the most popular benefits of using Himalayan salt lamp. 1.Neutralize Electromagnetic Radiation. Everyday appliances such as televisions, cell phones, computers and tablets release positive ions into the air constantly. These and other common electronics can cause an overflow of electromagnetic radiation which, although invisible, is believed to cause some serious long-term effects. Constant exposure to electromagnetic radiation is known primarily to cause fatigue, increase stress and weaken the immune system. Himalayan salt lamps emit negative ions and cancel out positive ones. Therefore, by neutralizing electromagnetic-radiation, they help reduce artificial frequencies and even prevent static buildup. 2.Cleanse, Deodorize, and Purify Air. Himalayan pink salt lamps help clean the air through an operation called Hygroscopy, which attracts and absorbs contaminated water molecules from the immediate environment and locks them into the salt crystal. The process has the amazing ability to remove cigarette smoke, dust and other contaminants from the air. This benefit is particularly popular, as salty air acts as an overall health booster and can help clear the air passages. 3.Better Sleep. Over-exposure to positive ions reduces the brain’s blood and oxygen supply, which can lead to irregular sleeping patterns. The negative ions from a Himalayan salt lamp are said to reverse this effect, making them a popular sleep-aid. Also, in direct relation to chromotherapy, the soothing light can help people who suffer from insomnia. Plants too can help. 4.Raise Energy Levels. Positive ions deplete the body of energy, and it is believed that Himalayan salt lamps can actually do the opposite. The negative ions increase energy levels, which yields a refreshing effect similar to the feeling of rejuvenation achieved from spending time in nature.  5.Boost Blood Flow. Particular studies have suggested that negative ions, such as those emitted by Himalayan salt lamps, can accelerate blood flow. This boost helps to improve several disorders of the vascular system and can prevent certain damage to the lungs.  6.Enhance Mood. Many studies suggest that negative ions improve mood and energy levels by increasing serotonin in the brain. Therefore, Himalayan salt lamps can benefit people suffering from seasonal affective disorder and other forms of depression.  When it comes to buying Himalayan pink salt lamps, coverage is determined by the size of the crystal. Smaller lamps are good for the average bedroom, while larger lamp are better for spaces like the living room or den. On average, 1 lb of Himalayan Pink Salt crystal will cleanse the air in approximately a 4′ x 4′ area.

War & Expansion: Crash Course US History #17
In which John Green teaches you about the Mexican-American War in the late 1840s, and the expansion of the United States into the western end of North America. In this episode of Crash Course, US territory finally reaches from the Atlantic coast to the Pacific Ocean. After Oregon was secured from the UK and the southwest was ceded by Mexico, that is. Famous Americans abound in this episode, including James K Polk (Young Hickory, Napoleon of the Stump), Martin Van Buren, Zachary Taylor, and Winfield Scott. You'll also learn about the California Gold Rush of 1848, and California's admission as a state, which necessitated the Compromise of 1850. Once more slavery is a crucial issue. Something is going to have to be done about slavery, I think. Maybe it will come to a head next week.

How Do Kidney Stones Form? How Can We Prevent Them? Animation Video - Renal Calculi Pathophysiology
Kidney stone facts A kidney stone is a hard, crystalline mineral material formed within the kidney or urinary tract. Nephrolithiasis is the medical term for kidney stones. Symptoms of a kidney stone include flank pain (the pain can be quite severe) and blood in the urine (hematuria). Kidney stones form when there is a decrease in urine volume and/or an excess of stone-forming substances in the urine. Dehydration is a major risk factor for kidney stone formation. People with certain medical conditions, such as gout, and those who take certain medications or supplements are at risk for kidney stones. Diet and hereditary factors are also related to stone formation. Diagnosis of kidney stones is best accomplished using an ultrasound, IVP, or a CT scan. Most kidney stones will pass through the ureter to the bladder on their own with time. Treatment includes pain-control medications and, in some cases, medications to facilitate the passage of urine. If needed, lithotripsy or surgical techniques may be used for stones which do not pass through the ureter to the bladder on their own. A kidney stone, also known as a renal calculus or nephrolith, is a calculus formed in the kidneys from minerals in the urine. Kidney stones typically leave the body by passage in the urine stream, and many stones are formed and passed without causing symptoms. If stones grow to sufficient size (usually at least 3 millimeters (0.12 in)) they can cause blockage of the ureter. This leads to pain, most commonly beginning in the flank or lower back and often radiating to the groin or genitals. This pain is often known as renal colic and typically comes in waves lasting 20 to 60 minutes. Other associated symptoms include: nausea, vomiting, fever, blood in the urine, pus in the urine, and painful urination. The diagnosis of kidney stones is made on the basis of information obtained from the history, physical examination, urinalysis, and radiographic studies. Ultrasound examination and blood tests may also aid in the diagnosis. Urinary stones are typically classified by their location in the kidney (nephrolithiasis), ureter (ureterolithiasis), or bladder (cystolithiasis), or by their chemical composition (calcium-containing, struvite, uric acid, or other compounds). Slightly more men are affected than women. Blockage of the ureter causes decreased kidney function and dilation of the kidney. In those who have previously had stones, prevention is recommended by drinking fluids such that more than two liters of urine is produced per day. If this is not effective enough, thiazide diuretic, citrate or allopurinal may be taken. It is recommended that soft drinks containing phosphoric acid (typically colas) be avoided. When a stone causes no symptoms, watchful waiting is a valid option. For stones which are causing symptoms, pain control is usually the first measure, using medications such as nonsteroidal anti-inflammatory drugs or opioids. More severe cases may require procedures. For example, some stones can be shattered into smaller fragments using extracorporeal shock wave lithotripsy. Some cases require more invasive procedures. Examples of these are cystoscopic procedures such as laser lithotripsy or percutaneous techniques such as percutaneous nephrolithotomy. Sometimes, a tube (ureteral stent) may be placed in the ureter to bypass the obstruction and alleviate the symptoms, as well as to prevent ureteral stricture after ureteroscopic stone removal. Prevention of kidney stones may include a combination of lifestyle changes and medications. Lifestyle changes You may reduce your risk of kidney stones if you: Drink water throughout the day. For people with a history of kidney stones, doctors usually recommend passing about 2.6 quarts (2.5 liters) of urine a day. Your doctor may ask that you measure your urine output to make sure that you're drinking enough water. If you live in a hot, dry climate or you exercise frequently, you may need to drink even more water to produce enough urine. If your urine is light and clear, you're likely drinking enough water. Eat fewer oxalate-rich foods. If you tend to form calcium oxalate stones, your doctor may recommend restricting foods rich in oxalates. These include rhubarb, beets, okra, spinach, Swiss chard, sweet potatoes, nuts, tea, chocolate and soy products. Choose a diet low in salt and animal protein. Reduce the amount of salt you eat and choose nonanimal protein sources, such as legumes. Consider using a salt substitute.
