- Abstract:
-
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 report produced from this project presents data for samples of periphyton and water collected in 1995 and 1996 from Water Conservation Areas, the Big Cypress National Preserve, and the Everglades National Park in south Florida. Periphyton samples were analyzed for concentrations of total mercury, methylmercury, nitrogen, phosphorus, organic carbon, and inorganic carbon. Water-column samples collected on the same dates as the periphyton samples were analyzed for concentrations of major ions.
- Purpose:
-
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?
- Supplemental_Information:
-
This project is now part of the Aquatic Cycling of Mercury in the Everglades (ACME) project

-
When possible, periphyton was collected by manually lifting floating periphyton mats from the water and transferring them to plastic bags. If the periphytic algae was attached to submerged aquatic plants, the plant stems were cut and the whole unit of plant and periphytic algae was collected.
Periphyton samples were air-dried in the laboratory in a laminar flow hood to maintain a stream of filtered air across them. Whole samples from each site were ground and aliquants were removed for analysis. Total mercury was determined by cold vapor absorption spectroscopy. Methylmercury and other organomercury compounds were extracted using supercritical fluid carbon dioxide and quantitated using liquid chromatography with electrochemical detection.
