Mercury transfer from river sediments (treated with labelled mercuric chloride) to freshwater fish (Lebistes reticulata) (wet weight, 29 to 869 mg) was observed for 150 days. Release rate from the sediment indicates a half-life of 12 to 20 years. The amount taken up by the fish varied widely (up to 600 percent differences), but half-lives for clearance were all between 38 and 75 days. No correlation was found between mercury uptake rate and either size or sex of fish.
