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 FDA has been measuring total arsenic concentrations in foods, including rice and juices, through its Total Diet Study program since 1991. 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.
