The direct uptake (excluding the food chain) of different dissolved mercury compounds by female Poecilia reticulata was studied. Using radiochemical tracers the authors investigated: (1) accumulation rates as a function of the chemical form of the dissolved Hg compounds; (2) accumulation rates as a function of the Hg concentration in the water; and, (3) the release of incorporated Hg in deionized water as a function of the Hg conpound and the incorporation time. It was proposed that, in the case of the complex compounds, the complexing groups may have a screening effect, so that adsorption at the surface of the cells is insignificant or non-existent. This was supported by the finding of a direct relationship between free Hg in the water and rate of accumulation. The release of inorganic Hg was found to be about 17 times as fast as the release incorporated methyl-HgCl.
