Arsenic 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.

Arsenic Poisoning Arsenic is considered to be a heavy metal, and arsenic toxicity shares some features with poisonings by other heavy metals. Historically, arsenic has been used as a medicinal agent, a pigment, a pesticide, and an agent with intent to harm (use with criminal intent).

ChemNote: Arsenic Poisoning Arsenic can penetrate into the body through the skin or the lungs but Arsenic mainly enters via drinking water or food that has been eaten. Most Arsenic compounds are soluble in water to some extent and thus are easily transported in the blood stream and assimilated by the body.

Arsenic Summary: Arsenic is a naturally occurring element widely distributed in the earth's crust. In the environment, arsenic is combined with oxygen, chlorine, and sulfur to form inorganic arsenic compounds. Arsenic in animals and plants combines with carbon and hydrogen to form organic arsenic compounds.

Arsenic Poisoning / Arsenicosis Arsenic poisoning or arsenicosis is a condition that is caused by consuming, absorbing or inhaling more than the optimum levels of arsenic, which is a semi-metallic element that is capable of forming an array of poisonous compounds. It is present in ground water all over the world.

Questions & Answers: Arsenic in Rice and Rice Products What is arsenic? Arsenic is an element in the Earth’s crust, and is present in water, air, and soil. It occurs both naturally in the environment and as a result of human activity, including from erosion of arsenic-containing rocks, volcanic eruptions, contamination from mining and smelting ores and previous or current use of arsenic-containing pesticides.

Arsenic Properties of Arsenic. Arsenic has atomic number 33, so it has 33 electrons in the configuration 1s 2 2s 2 2p 6 3s 2 3p 2 3d 10 4s 2 4p 3. The same outer shell s 2 p 3 is shared by N, P, Sb and Bi, the two lighter elements above it in the periodic table, and the two heavier elements below.rsenic by itself likes to form the tetrahedral molecule As 4, in which each As is bound to the other three covalently (by sharing electrons). Phosphorus does exactly the same thing. As 4 is a yellowish gas that condenses to a yellow, waxy solid with density about 2.0 g/cc. The gas has a characteristic garlic-like odor.

- 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.

Arsenic 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.rsenic 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.

- 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.

Other health effects may include blood vessel damage, high blood pressure, nerve damage, anemia, stomach upsets, diabetes, and skin changes.

- Drinking/Eating. Marine fish and seafood contain naturally high amounts of arsenic. However, the arsenic in these foods is a non-toxic form called fish arsenic.. Calcium supplements made from seashells may also contain high levels of arsenic.Arsenic has been found in private drinking wells throughout Wisconsin.ong-term exposure to toxic forms of arsenic may affect the following: Cancer-Arsenic has been associated with certain types of skin cancer. Some studies also show a possible link with lung, bladder, liver, colon, and kidney cancers. Skin-Very high exposure to arsenic can cause noticeable changes to skin and nails.

- 中国 (Chinese). Arsenic is present in the environment as a naturally occurring substance or as a result of contamination from human activity. It is found in water, air, food, and soil in organic and inorganic forms.rsenic may be present in many foods including grains, fruits, and vegetables where it is present due to absorption through the soil and water. While most crops don’t readily take up much arsenic from the ground, rice is different because it takes up arsenic from soil and water more readily than other grains.

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 is a metalloid. It can exist in various allotropes, although only the gray form has important use in industry.he most common oxidation states for arsenic are: −3 in the arsenides, such as alloy-like intermetallic compounds; and +3 in the arsenites, arsenates(III), and most organoarsenic compounds. Arsenic also bonds readily to itself as seen in the square As 3− 4 ions in the mineral skutterudite.

- A person can come into contact with arsenic in many different ways. Since it is a natural part of the environment, everyone is exposed to small amounts of arsenic. For most people, the largest source of arsenic is in the food we eat. Most foods, including vegetables, fish, and seafood, contain some arsenic. Arsenic in groundwater can enter the body by drinking the water or by eating food cooked in the water. Arsenic does not evaporate into the air and is not easily absorbed through the skin.
