At fist we discuss the methylmercury contamination which happened in Japan, as well as the strong measures taken in order to revert the process. The results of the main researches in Brazil, including the mercury concentrations for the most affected regions by gold mining activities are presented. Samples of blood, urine and hair from prospectors and the riverine population, and mercvury content of fish, were compared with those of the Japanese outbreak. The study includes the amazonian regions close to the rivers Madeira, Tapajos, Negro, Teles Pires, Fresco (Xingus's tributary) and Mato Grosso swamplands (Pantanal). This study deals with many subjects of interest such as fish trophic levels, correlation between Hg intake via fish ingestion and Hg in hair samples, biomagnification and finally the percentages of the organic form of the metal. Although the Hg contamination is high in the Amazon for the fish and populations ans is a reason for concern, according to the critical values of WHO, it is not high enough to consider Minamata disease as an imminent risk to Brazil. |
