“…Os estudos de Lemier e colaboradores, na Amazônia, abordando o papel do Se com relação ao Hg, foram realizados na Região do Rio Tapajós, na Amazônia Central (Lemire et al, 2006;Lemire et al, 2008;Lemire et al, 2010;Lemire et al, 2011 Madeira, e onde se observa que as crianças com dieta nativa têm níveis maiores deste elemento que as crianças localizadas mais perto de áreas urbanas, com uma influência de alimentos industrializados na dieta (Rocha et al, 2014 (Grandjean et al, 1999;Cordier et al, 2002 Norte (Verdon et al, 1991;Rosenberg et al, 1997;Mailman et al, 2006 La Grande complexo hidroelétrico (Schetagne et al, 2000;Hylander et al, 2006).…”

“…Existem estudos que reportam, também, um incremento nas áreas à jusante de hidrelétricas, podendo atingir concentrações que representem um risco para a saúde das populações que dependem do consumo do peixe para sua subsistência (Verdon et al, 1991;Boudou et al, 2005;Hylander et al, 2006 (Veiga et al, 1994;Malm, 1998;Roulet et al, 1999;Wasserman et al, 2001;Lacerda e Malm, 2008).…”

“…When a reservoir is created, submerged vegetation and organic material start to slowly decompose (Rodgers et al 1995), leading to a rise in the dissolution rate of organic carbon, increased release of mercury bound to organic material and higher net mercury methylation rates (Chan et al 2003). A deeper water column and increased decomposition creates anoxic conditions which are ideal for mercury methylation (Hylander et al 2006). A study of reservoirs up to 67 years old suggested that it may take 20-30 years before mercury concentrations return to pre-dam levels (Hylander et al 2006).…”

“…Due to current and past high mercury load in the Brazilian Amazon, the human exposure through fish consumption is a concern, especially for women in reproductive age as well children due to the impact of mercury on their neurodevelopment (Mozaffarian, 2006). The risk of elevated mercury concentrations in fish has become one of the most important issues in assessing the environmental impact of hydroelectric reservoirs (Hylander et al, 2006). However, in Brazil, few studies regarding mercury contamination have been carried out in areas of constructed reservoirs.…”
