The largest releases occurred in Arizona and Montana. The greatest releases to water occurred in Washington and Louisiana. Little is known about antimonys fate once released to soil. Some studies indicate that antimony is highly mobile in soils, while others conclude that it strongly adsorbs to soil. In water, it usually adheres to sediments.
Most antimony compounds show little or no tendency to accumulate in aquatic life.
No reliable data are available concerning health effects from long-term exposure to antimony in drinking water.
