“…The contents of protein and fat on fish vary significantly throughout the dry and rainy seasons. 14 Nevertheless, no methylmercury seasonal variability was observed in the muscle tissue of Serrasalmus rhombeus (Piranha) collected during the dry and rainy seasons at the Madeira river basin. A comparison of means using Student's t-test showed that mean MeHg for on dry and rainy seasons (0.69 AE 0.32 and 0.56 AE 0.27 mg kg À1 wet wt) presented no significant difference (t = 0.764; P b 0.23).…”

“…14 Tucunare (Ciclha temensis) and pescada (Plagioscion squamosissimus) seemed to be good indicator species for mercury pollution in the Tucuruí reservoir. 14 The carnivorous fish samples from the Bento Gomes river and the Fazenda Ipiranga lake at the Pantanal watersheds, which presented very low MeHg concentrations, can be considered as natural background ( 0.20 mg kg À1 wet wt 29 ). At the Pantanal watershed, high biological production might allow a large dilution capacity for any mercury present in the drainage.…”

“…Em outro trabalho, também realizado com peixes coletados no Rio Madeira porém em área de mineração (região do Rio Beni), a concentração de Hgtotal em peixe variou de 0,33 a 2,30 mg/kg (excedendo o valor limite permitido), enquanto nos onívoros e naqueles que se alimentam de lama os teores variaram de 0,02 a 0,19 mg/kg 17 . Muitos outros trabalhos [18][19][20][21][22][23][24] apresentam os teores de Hgtotal em peixes na faixa de 0,01 até 2,7 mg/kg.…”

“…Valores semelhantes foram encontrados em 2001 na mesma região 24 . Em geral, os valores de Hgtotal em peixes dos rios da Amazônia excedem 0,5 mg/kg [14][15][16][17][18][19][20][21][22][23][24][25] . Guimarães e colaboradores 26 encontraram um valor médio de Hg em peixes de rios do Amapá de 0,45 mg/kg, com valores máximos de até 0,65 mg/kg.…”
