Resumo: Initially, the heart concentration data does not seem relevant for use as a bioindicator, mainly due to its low concentration level. After applying a normalizing procedure, the heart results were a better Hg bioindicator (preconcentration coefficient 43.1) than those of the kidney (preconcentration coefficient 8.6). Cadmium preconcentration coefficients were 128.1, 195.3 and 5.2 for liver, kidney and heart, respectively, demonstrating the high accumulative capacity especially for the liver and kidneys. Iron is proposed as a normalizing element for the definiton of the regional natural biochemical population of the metals. In general, positive correlation coefficients were found between Fe and other metals.

Metais foram analisados em tecidos extraídos do coração, rins e fígado. Os baixos teores encontrados no coração inicialmente poderiam indicar que este órgão não traria resultados relevantes. Porém, mediante a aplicação de um procedimento de normalização, foram encontrados coeficientes de pré-concentração de 43.1 e de 8.6 para o coração e para os rins, respectivamente, indicando o tecido do coração como o melhor bioindicador para Hg. Para Cd, os coeficientes de pré-concentração foram 128.1, 195.3 e 5.2 para fígado, rins e coração, respectivamente, demonstrando alta capacidade acumulativa especialmente para fígado e rins. Foram encontradas altas correlações positivas entre o Fe e os metais Zn, Cu, Cd, Hg, Ag, Mn, Ni, Cr e Pb, indicando ser este elemento normalizante para definição da concentração bioquímica natural de metais na população de Arctocephalus australis no extremo sul do Brasil.2012-07-25T02:43:08Z2012-07-25T02:43:08Z2009info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfBARAJ, Besnik, et al.
