Bommanna G. Loganathan, Ph.D., is a professor of environmental/analytical chemistry at the Murray State University (MSU), Kentucky, USA. His current research involves investigations on the distribution, environmental transformation, and fate of persistent organic/organometallic pollutants in the environment and their effects on wildlife and human health. A major focus of his research is to evaluate status and trends of classical as well as emerging pollutants in man-made freshwater lakes such as Kentucky Lake in comparison with natural lakes and marine ecosystems, and to assess the effects of these compounds on human natural killer cells’ ability to kill cancer cells using in vitro assays. He is the author/co-author of over one hundred publications in peer reviewed journals and book chapters. Paul K.S. Lam is Chair Professor of biology at the City University of Hong Kong. He is currently Vice-President (Student Affairs) and Director of State Key Laboratory in Marine Pollution. Prof. Lam has extensive research experience in marine environmental research. He is particularly interested in the responses of organisms to toxic chemicals and algal toxins, as well as the risk assessment of these compounds. He is the author/co-author of over 240 publications in international refereed journals. Prof. Lam has been responsible for over 30 major government consultancy projects in the environmental field, including assessments of risks to Hong Kong cetaceans and waterbirds due to toxic contaminants.
