Metals in Aquatic Systems: A Review of Exposure, Bioaccumulation, and Toxicity Models (Metals and the Environmental Series)

Combining critical evaluations with a literature review, this work identifies and critiques fate and transport models for evaluation of exposure levels of metals in surface waters and sediments, examines strengths and weaknesses of bioaccumulation and toxicity models with respect to metals and metal compounds, and looks at chemical equilibrium models and their capabilities. Other models discussed include stand-alone hydrodynamic and sediment transport models. Paquin is an engineer in the private sector. Annotation ©2004 Book News, Inc., Portland, OR (booknews.com)

Paul Paquin, a Principal Engineer at HydroQual, Inc., Mahwah, New Jersey, has spent nearly 30 years developing fate and transport models of organic chemicals and metals and supervising model applications in exposure assessments for natural waters. He is currently working on a physiologically based model of metal bioaccumulation to develop a framework for relating organ-specific metal accumulation levels that arise from waterborne and dietary exposure to effects.

Kevin Farley is Associate Professor and Co-Chair of the Environmental Engineering Department, Manhattan College, Riverdale, New York, and a consultant to HydroQual, Inc., focusing on water quality modeling, fate and bioaccumulation of toxic chemicals in aquatic systems, and modeling of chemical fate and bioaccumulation of PCBs, mercury, dioxins, and PAHs in New York Harbor.

Robert Santore is an environmental scientist in the area of environmental and aquatic chemistry and chemical modeling. Mr. Santore developed the CHESS model to investigate the effects of atmospheric pollution on forest health and soil chemistry in the Adirondack Mountains of New York State. Recently, he has worked to evaluate the bioavailability and toxicity of heavy metals to aquatic organisms for HydroQual, Inc. in Camillus, New York.

Christos Kavvadas is an environmental engineer at HydroQual, Inc., Mahwah, New Jersey, with duties that include combined sewer-overflows field testing and data analyses; evaluation of measures for control of floatable materials; mathematical modeling of streams, estuaries, and reservoirs to evaluate the water quality impact of conventional and water quality pollutants; and data analyses for copper, silver, and zinc for evaluation of water quality criteria.

Kevin Mooney works for General Electric Company in Pittsfield, Massachusetts, studying the impact of conventional pollutants, organic chemicals, and metals in freshwater and estuarine systems through the application of mathematical and statistical analyses. His recent focus is on largescale field and analytical programs incorporated in mathematical modeling studies and ecological and human health risk assessments.

Richard Winfield has conducted environmental engineering studies since 1969, first in research, followed by consulting, then industry, and currently the EPA in New York. His water quality engineering analyses have been recognized by the International Association of Great Lakes Research and the American Society of Civil Engineering.

Kuen-Bing Wu, a Senior Project Manager at HydroQual, Inc., Mahwah, New Jersey, has more than 15 years of experience in the fate and transport modeling of conventional pollutants, organic chemicals, and metals in natural water systems. Mr. Wu is currently working on projects involving the development of the Biotic Ligand Model for copper, silver, cadmium, and nickel.

Dominic Di Toro, a principal consultant at HydroQual, Inc. and Distinguished Professor of Civil and Environmental Engineering at the University of Delaware, is an expert in the development and application of water quality models. He has served in a senior technical review capacity on EPA’s water quality criteria and sediment quality guideline development efforts, and has participated as expert consultant and principal investigator for industry and governmental agencies.
