A.S. Series 78-6
Elevated levels of mercury exist in various segments of the environment largely from past industrial and agricultural activities. Bacterial conversion of inorganic mercury to the biologically more important methylmercury promotes accumulation in animal bodies. Concentrations tend to increase as methylmercury is passed up the food chain through aquatic organisms to fish and water fowl and eventually to humans. It is this form of mercury, i.e., methylmercury, that has been implicated in egg shell thinning and lowered reproduction in birds.
