Topics covered in Volume 2 include lessons learned from three decades monitoring contaminants in Pacific Basin wildlife samples from the USA’s Marine Environmental Specimen Bank (Chapter 1); spatial and temporal trends of brominated flame retardants (Chapter 2), PCBs, pesticides, and dioxins/furans, in the environment and biota in the USA, Colombia (Chapter 3), China (Chapter 4), Korea (Chapter 5), and Japan (Chapter 6 and Chapter 7); emission of emerging pharmaceutical contaminants in the USA (Chapter 8) and Vietnam (Chapter 10); and possible application of bio-analytical assays in the biological impact assessment of persistent organic pollutants in Mangrove sediments in Southeast Asia with particular reference to Malaysia (Chapter 9). The collection of chapters in these volumes may serve as a reasonable representation of current and future trends of POCs in the Pacific Basin countries. It is hoped that the book can inspire students and researchers, as well as professionals, to facilitate the understanding of the environmental and biological behavior of these persistent chemicals and to help in the development of strategies and practices for protecting the global environment for future generations.
