Concentrations of total As was determined in water and muscle of the silverside (Odontesthes bonariensis) in four different water bodies (De la Plata River, Adela and Barranca Lagoons and Chasicó Lake, Argentina) using ICP-MS. In all cases, total As concentration in water (28.40-367.16µgL-1) exceeded national and international guidelines for the protection of the aquatic life. High concentrations of As (0.05-1.20 g kg-1 dry wt), were found in fish muscle however values were below international rec-ommended limits for human consumption. The implication of As in fish products in South America is becoming an urgent issue due to the need to asses exposure limits to human consumption.
