Abstract in Portuguese
Por Espectrofotometria de Absorção Atômica, sem chama, foram analisadas 64 amostras de tecidos muscular e vísceras de 32 peixes do Rio Mogi-Guaçu, São Paulo, Brasil. Os teores de mercúrio dos músculos são significamente maiores que os de vísceras. Os peixes do Rio Mogi-Guaçu das espécies examinadas, não oferecem risco como alimento para a saúde, pois possuem mercúrio com teores menores qúe 0,05 ppm (nÍvel permissível pelo WHO).

Abstract in English
By Flamless Atomic Absortion Spectrophotometry were analysed 64 samples of muscular tissue (flesh) and víscera of 32 fish from Mogi-Guaçu River, São Paulo, Brazil. The mercury contents of the muscles are significantly bigger than viscera's. The fish from Mogi-Guaçu River of examined species don't offer any danger as food for health, because they have mercury with contents lesser than 0,05 ppm (permissible level by WHO).
