Cycling and Speciation of Mercury in the Food Chain of South Florida
Methylmercury, a neurotoxin, is found in the game fish of south Florida. Samples of periphyton, the assemblage of microalgae that live in shallow submerged substrates which is home to, and food for, creatures that are the foundation of the food chain, have concentrations of methylmercury that range from non-detectable to tenths of a part per million on a dry weight basis.
The goal of this project is to answer the question, "How does mercury produced in the aquatic environment enter the food chain and become part of the body burden of animals such as game fish in south Florida?"
