Abstract/Summary Paracatu is a town adjoining to a gold mine in Minas Gerais, Brazil where we collected drinking water and soil/dust samples were collected from seven residential locations. Fifteen common food categories were also collected from local vendors and stores. Arsenic was analysed by ICP-MS. A physiologically based extraction test for bioaccessibility (BAc) of arsenic was conducted on the soil/dust samples. Water arsenic ranged from non-detected to 3.9 μg/L; soil arsenic 6-461 mg/kg in the <250 μm fraction; food arsenic were all below the level of quantification; and BAc ranged 1.8-7.5%. For the health risk assessment, Brazilian exposure parameters or international standards were applied together with site specific data obtained from this study to derive daily intake of arsenic. When the soil intake was adjusted for BAc the potential risk estimate to local residents is thought to be insignificant.
