“…The Hg levels were highest in fish from the Amazon and Pantanal, where the maximum concentrations in the muscles were 5.4 and 12.3 mg kg -1 , respectively (Alho and Vieira 1997;Dórea et al 2006).…”

“…Hg was related to both length (r 2 = 0.84) and weight (r 2 = 0.83); the slope was significantly different from zero (p \ 0.0001) for both regression lines. Weight was chosen over length to be consistent with previous studies using this species (Belger and Forsberg 2006; Dorea et al 2006).…”

“…Hg content in H. malabaricus varied across each river as follows: Corrientes: 0.15 ± 0.026 lg/g (n = 11), Napo: 0.16 ± 0.016 lg/g (n = 14) and Pastaza: 0.17 ± 0.024 lg/g (n = 10). Length and weight of fish were tested as predictors and showed similar results; since weight is more commonly used in studies of this species (Belger and Forsberg 2006;Dorea et al 2006;Lima et al 2005) we opted for this as our final predictor. Statistical results are reported with p-values of B0.01, B0.05, B0.1 and lower.…”

“…Estudos têm apontado altos teores de mercúrio (Hg) em peixes e nas populações ribeirinhas da Amazônia (HACON et al, 1997;DOREA;BARBOSA;SILVA, 2006;KASPER et al, 2007;SILVA et al, 2009). Aparentemente, uma conjugação de fatores naturais e antrópicos condiciona este resultado.…”
