Although once considered the main mechanism of detoxification, studies have implied the existence of other more important arsenic detoxification mechanisms in mammals. It occurs in soil and minerals and it may enter air, water and land through wind-blown dust and water run-off. Most arsenic gets into the body through ingestion of food or water. Arsenic is found in its native state, in realgar and orpiment as its sulfides, as arsenides and sulfaresenides of heavy metals, as arsenates, and as its oxide. Arsenic is a naturally occurring, poisonous element found in the soil. Arsenic's symbol is As and its atomic number is 33. Arsenic is everywhere in nature. It is also used to preserve pressure-treated wood. Arsenic is a naturally occurring chemical element found throughout our environment and its living systems. The inorganic forms of arsenic are the harmful forms, while most of the organic forms of arsenic are essentially harmless. It is an FDA-approved prescription drug. Arsenic can also occur in an organic form. Arsenic Arsenic is a naturally occurring element that is found in combination with either inorganic or organic substances to form many different compounds. Arsenic in drinking water is a problem in many countries around the world, including Bangladesh, Chile, China, Vietnam, Taiwan, India, and the United States.1 Arsenic may also be found in foods, including rice and some fish, where it is present due to uptake from soil and water. Some wells have arsenic levels as high as 350 µg/L. Arsenic can enter groundwater through erosion and weathering of soils, minerals, and ores. These findings provide evidence to support an interaction between folate and arsenic metabolism. Inorganic arsenic is naturally present at high levels in the groundwater of certain countries, including the United States. Consequently, such foods need to be tested for both inorganic and organic arsenic levels. Arsenic is commonly found in many foods both in its relatively nontoxic organic form, and also in the more toxic inorganic form. Arsenic and Antimony are almost identical. Once released, arsenic remains in the environment for a long time. Arsenic is a chemical present in the environment as a naturally occurring substance and as a result of human activity. ; Butte, Mont. Background Information. The most common mineral is Mispickel or arsenopyrite (FeSAs), which can be heated to sublime arsenic, leaving ferrous sulfide. For most people, food and water are the biggest sources of arsenic exposure. Also, arsenic trioxide is LIKELY SAFE when given intravenously (by IV) to adults by a healthcare provider. High arsenic levels in private wells may come from certain arsenic containing fertilizers used in the past or industrial waste. 4 A new study from the NTP Laboratory that replicates how humans are exposed to arsenic through their whole lifetime found that mice exposed to low concentrations of arsenic in drinking water developed lung cancer. The main route of arsenic excretion is in the urine. It is one of many natural elements found in air, water, and soil, and virtually all crop plants take up arsenic. Arsenic is a naturally-occurring element in rocks and soil. Arsenic is a known human carcinogen associated with skin, lung, bladder, kidney, and liver cancer. Arsenic is a naturally occurring element that’s found in soil and water. Arsenic may be found alone as a metal, or more commonly as a metal-like compound. Arsenic is an element in the environment that can be found naturally in rocks and soil, water, air, and in plants and animals. Organic arsenic is less toxic than inorganic arsenic, and accounts for most of the arsenic humans are exposed to, primarily through food and water. Chemical properties Arsenic is a metalloid. Arsenic and its compounds are poisonous. Arsenic is made on an industrial scale by heating appropriate minerals in the absence of air. Learn more about arsenic in private well water through the The Minnesota Arsenic Study (2000). After about 10 years drinking that water symptoms extend to skin and internal cancers. There are trace amounts of arsenic in nearly all of the foods and beverages we consume, including vegetables, fruits, juices, rice, grains, seafood, meat, and wine. Arsenic poisoning, or arsenicosis, occurs after the ingestion or inhalation of high levels of arsenic. Today, most commercial arsenic is obtained by heating arsenopyrite. It is found in water, air, food and soil. An FDA spokesperson says that the arsenic levels CR found in Starkey Spring Water meet the agency’s standard for the heavy metal. Arsenic contamination of groundwater is a form of groundwater pollution which is often due to naturally occurring high concentrations of arsenic in deeper levels of groundwater.It is a high-profile problem due to the use of deep tube wells for water supply in the Ganges Delta, causing serious arsenic poisoning to large numbers of people. These compounds occur either naturally or as a result of mining, ore smelting, and industrial use of arsenic. It can also be released into the environment from some man-made sources. It is an example of a metalloid or semimetal, with properties of both metals and nonmetals.It is found in nature as a single stable isotope, arsenic-75. For example, some scientific studies have shown that two forms of organic arsenic found in certain foods, dimethylarsinic acid (DMA) and monomethylarsonic acid (MMA), may be a health concern.
