Inorganic arsenic is found in industry, in copper-chromate-arsenate treated lumber, and in private well water in some parts of the country. Organic arsenic is found in many foods and particularly in some shellfish. The organic forms and amounts of arsenic found in seafood are generally considered to be nontoxic.
Arsenic is a natural element that can be found in rocks and soil, water, air, and in plants and animals. It can also be released into the environment from some agricultural and industrial sources. Although it is sometimes found in its pure form as a steel grey metal, arsenic is usually part of ...
It is present in many different minerals. About one third of the arsenic in the atmosphere comes from natural sources, such as volcanoes, and the rest comes from man-made sources. Due to natural geological contamination, high levels of arsenic can be found in drinking water that has come from deep drilled wells.
Arsenic is found in the smelter dust from copper, gold, and lead smelters, and is recovered primarily from copper refinement dust. On roasting arsenopyrite in air, arsenic sublimes as arsenic(III) oxide leaving iron oxides, while roasting without air results in the production of gray arsenic.

Arsenic can be found naturally on earth in small concentrations. It occurs in soil and minerals and it may enter air, water and land through wind-blown dust and water run-off. Arsenic in the atmosphere comes from various sources: vulcanoes release about 3000 tonnes per year and microorganisms release volatile methylarsines to the extent of 20 ...
In 2011, CR found elevated levels of inorganic arsenic and lead in apple and grape juices. Our most recent tests were conducted to see whether products have improved since then, to examine other ...
Arsenic is an element found in nature, and in man-made products, including some pesticides. Low levels of arsenic are found in soil, water and air. The element is taken up by plants as they grow ...
Arsenic Arsenic is a naturally occurring element that is found in combination with either inorganic or organic substances to form many different compounds. Inorganic arsenic compounds are found in soils, sediments, and groundwater. These compounds occur either naturally or as a result of mining, ore smelting, and industrial use of arsenic.
Arsenic is a toxic substance found in some foods, especially rice and rice-based products. This is a major concern for people who eat a lot of rice.
