Tissue-specific mercury concentrations in two catfish species from the Brazilian coast
Brazilian Journal of Oceanography, 2012 Some regions of Brazil have particularly high levels of mercury (Hg) emissions due to industrial activities, and their fish species may therefore suffer high levels of contamination through bioaccumulation. In this paper we assess Hg contamination in the
