“…In the absence of consumption of fish with high concentrations of MeHg the mean concentration of total mercury in whole blood is probably of the order of 5-10 g/L (IPCS, 1991). In persons with occupational exposure levels ranging from 20 to 100 g/L are common and they may be even increased to levels above 500 g/L with heavy consumption of contaminated fish (Schü tz, 1994). The higher total mercury levels observed in the control group probably mainly reflect a higher proportion of fish eaters in the control group.…”

“…If blood is used for the biological monitoring of exposure to Hg(0) vapor and total mercury in blood is measured, the confounding exposure to methyl mercury (MeHg) from the consumption of MeHg-contaminated fish, the major source of exposure to MeHg, should be taken into consideration (IPCS, 1991;Barrega rd, 1993, Schü tz, 1994. The problem of interference from MeHg is not so important when analyzing urine since about 90% of the total excretion of MeHg in man is by fecal route (Berlin, 1986;IPCS, 1991).…”

“…Alguns estudos que mostraram a interação, função protetora, do selênio com o mercúrio: em algas, camarões, caranguejos, ostras, peixes (Eisler 1985) e mamíferos (Dietz et al 2000, Wagemann et al 2000, Cardellicchio et al 2002, Chen et al 2002, Endo et al 2002. Esse efeito é devido à existência de uma interação entre o mercúrio e as selenoproteínas, que influi tanto no metabolismo quanto no efeito tóxico do metilmercúrio nos organismos marinhos (Schultz et al 1994), demetilando o metilmercúrio e formando os grânulos inertes de HgSe, que se depositam principalmente no fígado e rins dos mamíferos (Endo et al 2002). Conseqüentemente, a toxicidade do metilmercúrio tende a diminuir (Schultz et al 1994).…”

Conseqüentemente, a toxicidade do metilmercúrio tende a diminuir (Schultz et al 1994). A biota aquática, especialmente os mamíferos marinhos, apresenta uma significante correlação entre as concentrações molares de Hg e de Se no tecido muscular e no fígado (Palmisano et al 1995, Dietz et al 2000, Kehrig et al 2004.…”
