Research in the environmental health area addresses numerous aspects affecting aquatic systems including environmental chemistry, ecotoxicology, risk assessment, and multiple stressors  acting on an interconnected system in a changing world. Activities include the exploration of the sources, transport, fate, bioavailability, and impacts of contaminants in ecosystems and on public health as well environmental factors impacting seafood and water supplies.

Principal Investigators

Dr. Robert Hale: brominated diphenyl ethers, polychlorinated biphenyls, land-applied sewage sludge, polycyclic aromatic hydrocarbons, pesticides and organochlorines, and marine plastics.

Dr. Michael Newman:  ecotoxicology, risk assessment, inorganic contaminants in aquatic systems, toxicity models, and water quality.

Dr. Juliette Smith: ecology, ecotoxicology, and chemistry of natural toxins produced by harmful algal blooms (HABs).

Dr. Michael Unger:  tributyltin, polycyclic aromatic hydrocarbons, kepone, and pesticides.
