Toxicity and Organ Distribution of Mercury in Freshwater Fish () after Exposure to Water Contaminated Mercury (HgII).

The purpose of this study was to investigate the toxicity and the distribution of mercury (Hg) in the main tissues of freshwater fish (Oreochromis niloticus) after being exposed to water containing Hg(II). A sample group of 10 fish, of mean weight 80-100 g wet weight, were exposed to different concentrations of Hg (0.0012; 0.
