Resumo: We measured lead and cadmium concentrations in samples of mineral mixtures commercialized in Londrina city. Lead and cadmium content were determined by inductively coupled plasma atomic emission spectrometry. Considering maximum concentrations recommended by National Research Council (1996) and Association of American Feed Control Officials Incorporated (2001), of the 10 analyzed samples, 06 had values greater than 30 ppm of lead and all of them had values greater than 0.5 ppm of cadmium. These findings show the necessity for careful industrial monitoring because some mineral mixtures contain sufficient lead and cadmium to cause bovine toxicity.

Os metais pesados foram determinados pela técnica de espectrofotometria de absorção atômica por plasma de indução acoplada. Considerando como parâmetro de comparação às referências do National Research Council (1996) e a Association of American Feed Control Officials Incorporated (2001), em 10 diferentes marcas analisadas, seis apresentaram níveis de chumbo inorgânico superiores ao limite máximo aceitável que é de 30 ppm. Contudo, em todas as amostras o nível de cádmio encontrado superou o limite de 0,5 ppm, que é o valor máximo aceitável. Os resultados demonstram a urgente necessidade de monitoramento junto aos fabricantes e/ou revendedores, pois algumas misturas minerais podem ser eminentemente perigosas, possibilitando efeitos cumulativos tóxicos de chumbo e cádmio inorgânico aos bovinos.UEL2004-05-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/225610.5433/1679-0359.2004v25n4p359Semina: Ciências Agrárias; Vol. 25 No. 4 (2004); 359-364Semina: Ciências Agrárias; v. 25 n. 4 (2004); 359-3641679-03591676-546Xreponame:Semina.
