It 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.
2 A Gardening on Lead-and Arsenic-Contaminated SoilsThe chemical elements lead and arsenic are potentially toxic to people. Although lead andarsenic occur naturally in the environment, their concentrations have increased, and they havebecome more widely distributed because of human activities.  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. 1 Chronic poisoning has a better outcome. 2  Arsenic is found in groundwater, many chemicals, and foods. 3 1 Inorganic arsenic is arsenic alone or combined with inorganic substances that are very toxic to most biologic systems, including humans. 2  Organic arsenic is arsenic combined with organic substances and may be non-toxic or far less toxic to many biologic systems than inorganic arsenic. 1 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. 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. Long-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. Arsenic poisoning is a medical condition caused by elevated levels of arsenic in the body. The dominant basis of arsenic poisoning is from ground water that naturally contains high concentrations of arsenic. A 2007 study found that over 137 million people in more than 70 countries are probably affected by arsenic poisoning from drinking water. Chronic arsenic poisoning results from drinking contaminated well water over a long period of time. Many aquifers contain high concentration of arsenic salts. The World Health Organization recommends a limit of 0.01 mg/L (10 parts per billion) of arsenic in 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. Long-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.

Activity it is found in, water, air, food and soil in organic and inorganic. forms The agency also monitors toxic elements, including arsenic, in a variety of domestic and imported foods under the Toxic Elements Program, with emphasis is placed on foods that children are likely to eat or drink, such as juices. 1  Questions & Answers on Arsenic. 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. The agency also monitors toxic elements, including arsenic, in a variety of domestic and imported foods under the Toxic Elements Program, with emphasis is placed on foods that children are likely to eat or drink, such as juices. 1  Questions & Answers on Arsenic. 1 Symptoms of arsenic poisoning vary with the type and concentration of the poison. 2  Inorganic arsenic may cause abdominal pains, destruction of red blood cells (hemolysis), shock, and death quickly. 1 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. 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. Inorganic arsenic compounds are mainly used to preserve wood.
