“…As variáveis da água influenciam a imobilização dos contaminantes no sedimento ou sua liberação e disponibilização para a coluna de água. A eutrofização interfere na ciclagem e no transporte destes contaminantes nos sistemas aquáticos (SCHAANING et al, 1996, SKEI et al, 2000COELHO et al, 2005;HE et al, 2008).…”

“…Wujiangdu and Yinzidu Reservoir;Feng et al, 2009aFeng et al, , 2009bMeng et al, 2010b). Furthermore, total-Hg concentrations in the Hongfeng Reservoir impacted by a coal-fired power plant were elevated and slightly increased with depth in water columns (He et al, 2008a(He et al, , 2008b. The Baihua Reservoir, which has a recent history of Hg pollution caused by waste water discharges from the Guizhou organic chemical plant (GOCP), utilising metallic Hg as a catalyst to produce acetic acid, exhibited high levels of total-Hg in the water body and in underlying sediments (Feng et al, 2003c(Feng et al, , 2004dHou et al, 2004;Yan et al, 2005).…”

“…In a comparison between an up to 30 years old reservoir (Wujiangdu Reservoir) and newly constructed ones (Hongjiadu and Suofengying Reservoirs), the latter category exhibits slightly lower MMHg concentrations (Yao et al, 2011). He et al (2008a) conducted a long-term monitoring study of the Hg load in inflows and the outflow of the Hongfeng Reservoir and found a good comparison concerning the MMHg concentration in the flows with the exception for the summer period when the MMHg level in the outflow was up to 6 times higher than that in inflows ( Fig. 7A and B).…”

“…25 Eutrophication may affect the biogeochemical cycling of mercury in reservoirs, playing an important role in its transport and immobilization. 45 These process changes strongly affect the chemical forms of mercury that can determine the bioavailability of mercury in water. Fish in eutrophic lakes, however, were often found to contain less mercury than those in oligotrophic lakes.…”

“…This phenomenon has been explained by the increasing algal biomass in eutrophic systems reducing mercury accumulation at higher trophic levels through the dilution of mercury in consumed algal cells. 45 The aquatic system of Balbina reservoir presents black waters and acid pH (see Table 1) that are rich in natural organic matter. A number of studies have demonstrated that MeHg bioaccumulation is higher in lower pH aquatic systems, 46 such as Balbina reservoir.…”
