“…According to Sampaio et al (2008), the SVE presents the worst indicators of fecal pollution on the coast of São Paulo. Moreover, moderate to high concentrations of metals (Cd, Ni, Cu, Zn, Cr) and organochlorines were observed in aquatic organisms and sediments from SVE (Abessa et al 2008;Lamparelli et al 2001;Carmo et al 2011).…”

Hematological parameter of demersal fish constitutes important measures of biological effects of seasonality and contaminants in sediments. We aimed to assess the hematological parameters and nuclear abnormalities, including micronuclei levels, in peripheral erythrocytes of flatfish Achirus lineatus collected in São Vicente Estuary in summer and winter. The number of lymphocytes was significantly higher in summer, whereas the number of neutrophils was significantly higher in winter. For other measured parameters, no significant differences were observed in spite of the levels of erythroblasts, leukocytes, thrombocytes, micronuclei and nuclear abnormality tended to be slightly higher in winter. Integrated analysis of data suggests that genotoxicity may be related to immunosuppression, although some types of leukocytes appear to act removing anomalous cells. Considering the contamination status of the Santos-São Vicente Estuarine system, the results provide an important contribution to knowledge of the hematological aspects of A.lineatus and its potential use as a bioindicator for monitoring estuarine sites.

Resumo No presente trabalho, a técnica de espectrometria de emissão óptica com plasma induzido por micro-ondas foi empregada para determinar as concentrações de Al, Cd, Cu, Hg, Mg, Sb e Zn em amostras de peixes (bagre, tainha, traíra, pintado e corvina) e de Al, Ba, Ca, Cd, Cr, Cu, Fe, Mg, Mn, Ni, Pb, Sb, Ti e Zn em amostras de camarão-rosa (Farfantepenaeus paulensis). As amostras foram preparadas usando a decomposição ácida com o sistema de refluxo. Para as análises de peixes, fez-se a comparação de dois sistemas de introdução de amostras no plasma: a nebulização convencional e o sistema multimode . Para se obterem as melhores condições utilizando o sistema multimode, parâmetros, como a concentração de HCl e do agente redutor NaBH4, foram investigados. A exatidão do método foi avaliada através de análises de materiais de referência certificados e de testes de adição de analito. As recuperações obtidas foram satisfatórias para ambas as amostras. Para os peixes, os melhores resultados foram obtidos usando o sistema multimode e as concentrações encontradas (em mg kg-1) foram 6,43 a 24,7 para Al; 0,41 a 6,6 para Cu; 168,2 a 211,2 para Mg, e 23,1 para Zn. Para as amostras de camarão-rosa, as concentrações máximas (em mg kg-1) encontradas foram: 92,1 para Al; 1.070 para Ca; 4,57 para Cu; 87,9 para Fe; 451 para Mg; 8,9 para Mn, e 29,2 para Zn. Todas as concentrações de Cd, Cu, Pb e Zn encontradas estão dentro dos limites permitidos pela legislação vigente no Brasil, para pescados. Os resultados obtidos mostraram a adequabilidade do método utilizando a técnica de MIP OES para determinação multielementar em amostras de peixe e camarão-rosa.

“…A large portion of the world's population lives in urban centers near estuarine coastlines, which places anthropogenic pressure on water resources due to the demands and wastes of such populations (Cunha et al, 2005;Carmo et al, 2011;Barbosa, 2006). It is estimated that approximately 75% of the world's population will be living within 160 km of a coastline by the year 2025 (Moura, 2009).…”

The present study evaluates physicochemical variables, perform a microbiological analysis as well as determine heavy metal concentrations in the water and muscle tissue of fishes from the Cachorros River. The analysis of metal concentrations in the estuarine water revealed high levels of Fe and Al, with values above the limits established by Brazilian legislation. The concentration of total coliforms and thermotolerant coliforms tended to be higher in the rainy season. Regarding metal concentrations in the muscle tissue of fishes, high levels of Pb and Cd were found, especially in carnivorous and detritivorous species, with values above the limits established by national legislation. Two-factor analysis of variance revealed that only Pb demonstrated a significant interaction between seasonality and the feeding habits of the fish fauna, with higher concentrations of this metal in the dry season among detritivorous species in comparison to herbivorous species. The present findings demonstrate the contamination pattern that has been occurring in the Cachorros River, as evidenced by the concentration of trace metals in both the water and muscle tissue of fishes, which are an important source of protein as well as an economic resource for the population of this river basin.
