Arsenic Arsenic and its compounds, especially the trioxide, are used in the production of pesticides, treated wood products, herbicides, and insecticides. These applications are declining, however. A few species of bacteria are able to use arsenic compounds as respiratory metabolites.he main use of metallic arsenic is for strengthening alloys of copper and especially lead (for example, in car batteries). Arsenic is a common n-type dopant in semiconductor electronic devices, and the optoelectronic compound gallium arsenide is the most common semiconductor in use after doped silicon.

US Geological Survey Arsenic Map Inorganic arsenic can occur in the environment in several forms but in drinking water it is mostly found as Arsenic III (trivalent arsenite) or Arsenic V (pentavalent arsenate). Arsenic III will convert to Arsenic V in water that is oxidized.

ChemNote: Arsenic Poisoning Sources of Exposure to Arsenic in Daily Life. 1  Most drinking water contains small amounts of Arsenic. 2  Arsenic was found in items such as wine, juice, syrup, glues and pigments. 3  Arsenic is found in many foods both as organic compounds such as methyl arsines, and as inorganic arsenates and arsinates.

- A small amount of arsenic is found in its native state. It is mainly found in minerals. The most common arsenic-containing mineral is arsenopyrite. Others include realgar, orpiment and enargite.Most arsenic is produced as a by-product of copper and lead refining. It can be obtained from arsenopyrite by heating, causing the arsenic to sublime and leave behind iron(II) sulfide.rsenic compounds are sometimes used as rat poisons and insecticides but their use is strictly controlled. Surprisingly, arsenic can also have medicinal applications. In Victorian times, Dr Fowler’s Solution (potassium arsenate dissolved in water) was a popular cure-all tonic that was even used by Charles Dickens.

- A less common form of arsenic found in nature is the silver-gray rock called arsenic trioxide, which also goes by several common names including elemental, native, pure and white arsenic. Arsenic trioxide is also important as a raw material for products containing arsenic.ome forms of arsenic are quite toxic; others are less so. Most arsenic compounds are undetectable to the senses, since they have no smell or taste. But when arsenic is heated-by bright sunlight or in a laboratory experiment-it passes directly from its solid state to a gas and gives off a distinctive garlic odor.

The Chemistry of Poisons â White Arsenic Other, more soluble compounds with lower toxicities are now more commonly used. Today, poisons using arsenic are rare; the last person to be convicted of using arsenic as a poison was Marcus Marymont, a US sergaent, who in 1958 used white arsenic to poison his wife.

Arsenic in Water Source of Arsenic in Water: Arsenic (As) is often used in wood preservation as well as in paint and dye production. It can also be a byproduct of other industrial or agricultural processes. Arsenic can enter ground water through farm run-off or industrial waste.

- Arsenic is a naturally occurring mineral found in soil, bedrock, and water. In its pure form, arsenic is a silver-gray or white brittle metal. Arsenic has no odor and is almost tasteless.Arsenic and its compounds have a variety of commercial uses.Manufacturers use arsenic to make other metals, glass, electronic components, and wood preservatives.rsenic level between 10 ppb and 500 ppb*. Do not drink your water or use it to prepare foods that require a lot of water (e.g., infant formula, soups, Jell-O, rice, coffee, tea) if the arsenic level is above 10 ppb. Washing foods and dishes in the water is safe, and is not a significant source of exposure.

What Is Arsenic and Why Is It in Food? Answer: Arsenic is a poisonous chemical often used in herbicides and pesticides and is classified as a Class 1 carcinogen, meaning it is highly toxic to humans. Other Class 1 carcinogens include asbestos, formaldehyde and hepatitis B and C viruses.

Arsenic Arsenic may also be found in foods, including rice and some fish, where it is present due to uptake from soil and water. It can also enter the body by breathing dust containing arsenic, or through the skin, though this is not a major route of exposure.

- Because arsenic is an element like carbon and oxygen it does not break down in the environment into simpler substances-though it can change form and combine with other elements into molecules that have different chemical properties. Some forms of arsenic are quite toxic; others are less so.

- Formerly the most important use of arsenic compounds, was as an insecticide sprayed in fields and orchards. This use has entirely disappeared in most countries, due to the poisonous nature of arsenic compounds.Arsenic contamination is a problem in some well-water and may be associated with mine drainage.ype: element. Description: Arsenic (As) is classed as a semi-metal, or metalloid. In nature it is commonly found as a metal in low levels in most soils and in higher concentrations associated with some copper, lead and zinc ores. The most common arsenic mineral is arsenopyrite, a compound of iron, arsenic, and sulfur.

- Arsenic is a chemical element with symbol As and atomic number 33. Arsenic occurs in many minerals, usually in conjunction with sulfur and metals, and also as a pure elemental crystal. Arsenic is a metalloid. It can exist in various allotropes, although only the gray form has important use in industry.he main use of metallic arsenic is for strengthening alloys of copper and especially lead (for example, in car batteries).

Arsenic inorganic arsenic or organic arsenic. 1  Inorganic forms of arsenic are found in soil, rock, and water. 2  Organic forms of arsenic are generally much less harmful to people than inorganic forms, and some are considered relatively risk free.se of drinking water containing more than 200 micrograms of inorganic arsenic per liter over many years has been linked to problems with the skin, blood circulation, lungs, and the nervous, immune and endocrine systems.

Arsenic The most important compounds of arsenic are arsenic (III) oxide, As 2 O 3, (' white arsenic '), the yellow sulfide orpiment (As 2 S 3) and red realgar (As 4 S 4), Paris Green, calcium arsenate, and lead hydrogen arsenate.The latter three have been used as agricultural insecticides and poisons.he most common oxidation states for arsenic are -3 (arsenides: usually alloy-like intermetallic compounds), +3 (arsenates(III) or arsenites, and most organoarsenic compounds), and +5 (arsenates(V): the most stable inorganic arsenic oxycompounds).

ARSENIC Arsenic is a trace element. It is found in several foods including seafood, poultry, grains (especially rice), bread, cereal products, mushrooms, and dairy products. Some forms of arsenic are used as medicine.Despite serious safety concerns, arsenic is often used as a part of extremely diluted homeopathic remedies that are used for digestive disorders, food poisoning, sleep problems (insomnia), allergies, anxiety, depression, and obsessive-compulsive disorder (OCD).rsenic is a trace element that occurs naturally in very small amounts in the diet. Its exact functions are not known. The estimated adult daily intake of arsenic from a typical diet is 12-50 mcg. A dietary requirement of 12-25 mcg/day has been suggested. In leukemia, arsenic trioxide increases death of cancer cells.

- 1 Arsenic is found in groundwater, many chemicals, and foods. 2  If arsenic is in the organic form, it is likely nontoxic or weakly toxic to humans, but inorganic arsenic can also be found in similar locations and materials and in high concentrations in industrial processes. Chronic poisoning has a better outcome. 2  Arsenic is found in groundwater, many chemicals, and foods. 3  If arsenic is in the organic form, it is likely nontoxic or weakly toxic to humans, but inorganic arsenic can also be found in similar locations and materials and in high concentrations in industrial processes.
