A survey of the levels of cadmium, lead and arsenic in different types of rice available on the Swedish retail market was carried out in 2001 – 2003. The types of rice included long and short grain, brown, white and parboiled white rice. The mean levels found were; total As: 0.20 mg kg-1, inorganic As: 0.11 mg kg-1, Cd: 0.024 mg kg-1 and Pb: 0.004 mg kg-1, ICP-MS was used for the determination of As (total and inorganic), after acid digestion. Lead and cadmium were determined using GFAAS, after dry ashing. In countries where rice is a staple food it may represent a significant contribution in relation to the Provisional Tolerable Weekly Intake for Cd and inorganic As.
