Mike Henry joined Mote Marine Laboratory in the summer of 1987 as a staff chemist. He now works in the Ecotoxicology program. This Program assesses what toxic substances are found in the marine environment, where they come from and where the go. Working closely with the other program areas, Mike is involved with extensive field studies backed up by controlled laboratory studies that address chemical changes and metabolic products produced by marine organisms exposed to toxins. A major focus of this program is the analysis of natural biotoxins and pesticides in water, air and marine animals, providing information required to understand how marine life and humans are exposed to biotoxins and in what amounts.
