The direct uptake of different dissolved mercury compounds by female POECILIA RETICULATA was investigated using Hg 203 labelled Hg(NO/sub 3/)/sub 2/ and CH/sub 3/HgCl dissolved in deionized water at concentrations of 0.1, 1, 5, 10, and 20 ng Hg/ml. Accumulation curves showed the uptake of mercury, 1 ng/ml, in the CH/sub 3/HgCl solution was about four times as fast as in the Hg(NO/sub 3/)/sub 2/ solution. In the presence of EDTA, cysteine, or glutathione the accumulation rates decreased. In general, the higher the Hg concentration as CH/sub 3/HgCl in the water, the higher the contaimination of the fish. The accumulation rate increased with increasing Hg concentration in the water, but the relative accumulation rate decreased with increasing contamination of the water. A brief explanation of the findings is included. (ND)
