“…Among these metals, Pb contributed most (32.4%) to the average HI of 40 TWTPs, followed by Cd (24.7%) and Cr (21.6%), which suggests that the three metals may be of serious health concerns for the local residents, since previous studies showed that Cr enrichment in the sediments of Yangtze River (Zhang et al 2009) and Huaihe River (Huang et al 2006) was widespread, and the sequence of the potential ecological risk posed by the metals in sediments of Yangtze River at Wanzhou Section was Cd > Pb > Cu > Zn > Cr (Fu et al 2009). These metals can be easily bio-accumulated in some fish species (Lombardi et al 2010;Malik et al 2010), so more concerns shoulds focus on the contamination of Pb, Cr and Cd in the source water in the region of Jiangsu.…”

In this study, we investigated the levels of eight metallic elements in source water of 40 tap water treatment plants (TWTPs) located along Yangtze River, Taihu Lake and Huaihe River in the section of Jiangsu Province, China during 2007-2009 and assessed the non-carcinogenic risks induced by the metals. Among the metals, Fe had the highest concentration (121.5 μg L( - 1)) and Pb contributed most (32.4%) to the average hazard index (HI) of 40 TWTPs, followed by Cd (24.7%) and Cr (21.6%). The average concentration of each metal was below the permissible limit of China and USA except for Pb. Both hazard quotients of individual metals and HI of total non-carcinogenic risk in each TWTP were lower than 1.0, suggesting that these pollutants posed negligible hazards to public health of local residents. Temporal and spatial comparisons showed that high HIs occurred more frequently in low water seasons, and the three TWTPs located along Huaihe River (Dongtai, Jinhu and Yishuichang) had relatively higher HIs.

“…The use of somatic indexes such as HSI, CF, and ∆K in environmental studies were considered useful tools to evaluate the influence of biotic factors in the accumulation of these types of contaminants (ADAMS; RYON, 1994;KARELS et al, 1998;COUILLARD et al, 1999;LOMBARDI et al, 2010). Azevedo et al (2009a) observed high HSI values in C. spixii from polluted sites in Santos-São Vicente estuary as compared with fish from a reference unpolluted area.…”

“…All biliary content was collect using a sterile syringe and stored at -20°C for subsequent analyses. Somatic indexes were calculated according with Vazoller (1996) and Lombardi et al (2010) The MFO system was measured in the microssomal fraction of the individual livers of C. spixi according with Livingstone (1988). Frozen livers (~1.00 g) were homogenized in buffer containing 10 mM Tris-HCl, 0.15 M KCl and 0.5 M sucrose (pH 7.6) and centrifuged three times: 500g for 15 min, 12,000g for 45 min and then at 100,000g for 90 min) Microssomal pellets were dissolved in 20 mM Tris-HCl and 20% glycerol (pH 7.6).…”

A B S T R A C TDifferent components of the mixed function oxidase (MFO) system and the levels of fluorescent aromatic compounds in bile (FACs) were measured in Cathorops spixii in order to assess the impact of polycyclic aromatic hydrocarbons (PAHs). Fish were sampled in an estuary (Santos/São Vicente) with a history of contamination by PAHs, mainly due to the presence of the industrial complex of Cubatão city and of another of low anthropogenic influence (Cananéia) on the Brazilian coast. FACs were higher in fish from the polluted site, and the PAH 5 and 6-ring metabolites were the most frequent -with 14% and 15%, respectively. Levels of the different components of the MFO system showed the same variation profile as the FACs for both estuaries. Therefore, the values found for somatic indexes and biomarkers with data of bile PAH metabolites indicate the presence of organic contaminants, especially in the area subject to the influence of the industrial complex on the Santos/São Vicente estuary. R E S U M ODiferentes componentes do sistema oxidase de função mista (MFO) e os níveis de compostos aromáticos fluorescentes em bile (FACS) foram determinados em Cathorops spixii a fim de avaliar o impacto de hidrocarbonetos policíclicos aromáticos (PAHs). Os peixes foram coletados em um estuário com histórico de contaminação por PAHs (Santos/São Vicente), devido principalmente a presença do complexo industrial na cidade de Cubatão e em outro com baixa influência antropogênica (Cananéia) na costa brasileira. FACs foram maiores nos peixes oriundos da área contaminada, sendo os metabolitos de HPAs com 5 e 6 anéis, os mais representativos com 14% e 15%, respectivamente. Os níveis dos diferentes componentes do sistema MFO mostraram o mesmo perfil de variação que os FACs em ambos os estuários. Portanto, os valores encontrados para os índices somáticos e os biomarcadores considerados, em associação com os dados de metabólitos biliares de PAHs, indicam a presença de contaminantes orgânicos, principalmente na área sob influência do complexo industrial no estuário de Santos/São Vicente.

“…The highest average concentration of copper was registered at the CP4 production center, at 0.0515 mg/L. The values above this concentration become toxic to fish and other aquatic organisms, even more so if they act synergistically with zinc (Lombardi et al, 2010;Sakulsak, 2012) (Table 5).…”

The bioaccumulation of the heavy metals Cu, Zn, Fe and Pb was determined in the livers, kidneys and muscles of Oncorhynchus mykiss trout at seven production centers in the province of Yauli, Junín-Peru. The determination and quantification of total heavy metals in water samples collected monthly from the production sites and in 28 trout that averaged 250 g and 27 cm was performed by atomic absorption spectrophotometry, according to the methodology recommended by FAO. Levels of Zn, Fe and Pb were found to exceed the environmental quality standards established by the Peruvian Ministry of the Environment for the rivers of the coast and highlands, as well as the quality standards of the European Union for the cultivation of trout, while levels of Cu conformed with those standards. Concentration of Cu, Zn, Fe and Pb in the livers, kidneys and muscles exceeded the maximum permissible limits established by the European Union for fish meat and by the Mexican official standard, NOM-027-SSA1-1993, for fresh, refrigerated and frozen fishery products, in the case of Pb. The correlation between the concentrations of copper, zinc, iron and lead in the water and the concentrations of these metals in the livers, kidneys and muscles is low and not significant, except for copper, which had a significant correlation.Keywords: atomic absorption spectrophotometry, bioaccumulation, heavy metals, trout. Bioacumulação de metais pesados em Oncorhynchus mykiss para exportação dos centros de produção dos Andes Centrais do Peru RESUMOA bioacumulação de metais pesados de Cu, Zn, Fe e Pb no fígado, rim e músculo da truta Oncorhynchus mykiss foi determinada em sete centros de produção na província de Yauli, Junín-Peru. A determinação e quantificação do total de metais pesados em amostras de água coletadas mensalmente nos locais de produção e em 28 trutas de 250 g e 27 cm em média foram realizadas por espectrofotometria de absorção atômica, de acordo com a metodologia recomendada pela FAO. Com exceção do Cu, alguns níveis de Zn, Fe e Pb foram encontrados na água em padrões de qualidade ambiental superiores aos estabelecidos pelo Ministério do Meio Ambiente do Peru para os rios do litoral e planalto, e aos padrões de qualidade da União Europeia para o cultivo da truta. A concentração de Cu, Zn, Fe e Pb no fígado, nos rins e nos músculos excedeu os limites máximos permitidos pela União Europeia para a carne de peixe; e pela NOM-027-SSA1-1993 mexicana para os produtos frescos da pesca, refrigerados e congelados, no caso de Pb. A correlação entre a concentração de cobre, zinco, ferro e chumbo em água e a concentração destes metais no fígado, rim e no músculo, é baixa e não significativa, exceto para cobre que teve correlação significativa.Palavras-chave: bioacumulação, espectrofotometria de absorção atômica, metais pesados, truta.
