Fundamental QSARs for Metal Ions
CRC Press – 2013 – 302 pages
Fundamental QSARs for Metal Ions describes the basic and essential applications of quantitative structure–activity relationships (QSARs) for regulatory or industrial scientists who need to predict metal ion bioactivity. It includes 194 QSARs that have been used to predict metal ion toxicity and 86 QSARs that have been used to predict metal ion bioconcentration, biosorption, and binding. It is an excellent sourcebook for academic, industrial, and government scientists and policy makers, and provides a wealth of information on the biological and chemical activities of metal ions as they impact health and the environment. Fundamental QSARs for Metal Ions was designed for regulatory and regulated organizations that need to use QSARs to predict metal ion bioactivity, as they now do for organic chemicals. It has the potential to eliminate resources to test the toxicity of metal ions or to promulgate regulations that require toxicity testing of metal ions because the book illustrates how to construct QSARs to predict metal ion toxicity. In addition, the book:

"Fundamental QSARs for Metal Ions, by authors who have made substantial contributions in the field, is an advanced-level, comprehensive treatment of the subject … Anyone wishing to undertake QSAR analysis would be well advised to consult Fundamental QSARs for Metal Ions. The references and the QSAR equations number in the hundreds with the latter incorporating dozens of different metal ions and their descriptors. …
The slow progress regarding an understanding of metal-ion toxicity should not deter the use of QSAR analyses in the future. … So, let the QSAR studies continue with Fundamental QSARs for Metal Ions as the indispensable guide and reference work …"

John D. Walker has fourty-four years of professional academic, industrial and government experience in environmental toxicology and chemistry. Since 1989 he has been Director of the Toxic Substances Control Act Interagency Testing Committee (ITC), The ITC is an independent advisory committee to the U.S. Environmental Protection Agency (U.S. EPA) Administrator with representatives from 14 U.S. Government organizations. The ITC’s statutory responsibility is to identify industrial chemicals that are likely to harm humans or the environment and recommend them for testing to develop data needed to assess their risks. Prior to being selected as the ITC’s Director John was a senior scientist with the U.S. EPA, a regulatory toxicologist with the U.S. Food and Drug Administration, an environmental scientist with Lockheed Martin and a Research Associate at the University of Maryland.
John received his bachelor’s degree in chemistry and biology magna cum laude from Kent State University where he was elected to Phi Beta Kappa. He studied microbiology at the University of Dayton where he was elected to Sigma Xi and studied aquatic toxicology at the Ohio State University’s Franz T. Stone Laboratory while earning his Ph.D. His M.P.H. is from the Johns Hopkins University School of Public Health.
John is a Charter Member of the Society of Environmental Toxicology and Chemistry (SETAC), an Emeritus Member of the American Society for Microbiology and the American Academy of Microbiology and a former Editor of SETAC’s International Journal, Environmental Toxicology and Chemistry. John co-authored the Laboratory Manual for Marine Microbiology and edited the book, QSARs for Pollution Prevention, Toxicity Screening, Risk Assessment and Web Applications. He has authored or co-authored 160 peer-reviewed publications and has written 140 abstracts of presentations for national and international professional society meetings. John was the first recipient of the American Fisheries Society/U.S. EPA Science Achievement Award in Biology/Ecology and has been awarded 5 U.S. EPA Bronze medals. He was awarded the U.S. EPA’s Unsung Hero
Award for his work with Special Olympics. John is married with four children and two grandchildren.
Michael C. Newman is currently the A. Marshall Acuff Jr. Professor of Marine Science at the College of William and Mary’s Virginia Institute of Marine Science, where he also served as Dean of Graduate Studies for the School of Marine Sciences from 1999 to 2002. Previously, he was a faculty member at the University of Georgia’s Savannah River Ecology Laboratory. His research interests include quantitative ecotoxicology, environmental statistics, risk assessment, population effects of contaminants, metal chemistry and effects, and bioaccumulation and biomagnifications modeling. In addition to more than 125 articles, he has authored five books and edited another six on these topics. The English edition and Mandarin and Turkish translations of Fundamentals of Ecotoxicology have been adopted widely as the textbook for introductory Ecotoxicology courses.
He has taught at universities throughout the world, including the College of William and Mary, University of CaliforniaSan Diego, University of Georgia, University of South Carolina, Jagiellonian University (Poland), University of Antwerp (Belgium), University of Hong Kong, University of Joensuu (Finland), University of KoblenzLandau (Germany), University of Technology, Sydney (Australia), Royal Holloway University of London (UK), Central China Normal University, and Xiamen University (China). He has served numerous international, national, and regional organizations, including the OECD, U.S. EPA Science Advisory Board, Hong Kong Areas of Excellence Committee, and the U.S. National Academy of Science NRC. In 2004, the Society of Environmental Toxicology and Chemistry awarded him its Founders Award, "the highest SETAC award, given to a person with an outstanding career who has made a clearly identifiable contribution in the environmental sciences."
