Total butyltin (BTs: MBT + DBT + TBT) concentrations in dolphin liver ranged between 110 and 11 340 ng/g (wet wt) with a mean value of 1400 ng/ g. Butyltin concentrations in bottlenose dolphins were higher than those reported from other locations. The liver of a adult male dolphin collected in 1989 had the highest BT concentration (11 340 ng/g wet wt) reported. The concentrations of butyltins increased during the early life stages until maturity, for both sexes, and then tended to remain constant. Analysis of fish muscle collected from the Gulf of Mexico indicated the existence of recent inputs of TBT. The biomagnification factor of BTs in dolphins, on average, was 1.0 with the highest value of 6.8. In addition to polychlorinated biphenyls (PCBs), the presence of noticeable concentrations of TBT and DBT, which are potential immunosuppressing agents, might have also contributed to bottlenose dolphin mortality events in the U.S. Atlantic and Gulf coasts.

For comparison, pine needle samples from the highly contaminated Linden Chemicals and Plastics (LCP) Superfund site in Brunswick, Georgia, also were analyzed. RGB concentrations in residential Kentucky ranged from 1.91 ng/g diy wt. to 12 ng/g dry wt. These sites were comparatively less polluted than those from the Superfund site, that had concentrations ranging from 15 ng/g dry wt. to 34 ng/g dry wt. Finger printing of RGB contamination sources was possible using pine needle RGB profiles. RCB-28 and RCB-52, RCB-101, RGB-153 and RGB-138 in pine needles indicated uptake of Aroclors-1016 and-1242,-1254,-1260 in Kentucky sites. Rine needles from the Superfund site and its vicinity contained higher chlorinated RGBs especially, RGB-196, PGB-199, and PGB-206 characteristic of Aroclor 1268. When the toxic equivalencies (TEQs) of RGBs were compared, Kentucky pine needles were only slightly lower (0.03-0.17 pg/g dry wt) than pine needles from the Superfund site (0.24-0.48 pg/g dry wt). Considering the homologue distribution of RGBs in pine needles from Kentucky and the Superfund site, lower chlorinated RGBs seem to have traveled farther than the higher chlorinated RGBs.

The organohalogens, including chlorinated, brominated and fluorinated compounds, are ubiquitous in the environmental landscape and biota; with human exposures occurring through multiple pathways such as direct skin contact, inhalation, drinking water, and food. Exposure to chlorinated compounds is known to cause reproductive, neurotoxic, immunotoxic, endocrine, behavioral, and carcinogenic effects in both wildlife and humans. Polybrominated diphenyl ethers (PBDEs), the perfluorinated chemicals (PFCs), triclosan, triclocarban, tetrabromobishphenol A (TBBPA) and hexabromocyclododecane (HBCD), are considered as emerging new environmental pollutants. Based on their current and probable future use and their persistent chemical properties, it can be predicted that human exposure to these compounds will continue to increase. The health effects of these emerging chemical pollutants are of concern for the twenty-first century and beyond.

Fishes treated in higher concentrations developed vertebral deformity and the deformation was prominent after 89th and I15th day. The levels of the vertebral minerals such as calcium, magnesium and phosphorus lowered in' all exposure concentrations and minerals lost were directly proportional to the toxic concentrations. Nearly 2/3 of skeletal mineral composition was eliminated in the deformed fish. Vertebral fracture was attributed mainly to the large amount of vertebral components eliminated from the vertebrae. Vertebral cadmium accumulation was also linear in relation to the experimental concentrations.

Global Contamination Trends of Persistent Organic Chemicals provides comprehensive coverage of spatial and temporal trends of classical and emerging contaminants in aquatic, terrestrial, and marine ecosystems, including the Arctic and Antarctic ecosystems. Compiled by an international group of experts, this volume covers:
Spatial and temporal trends of polychlorinated biphenyls (PCBs), chlorinated pesticides, polychlorinated naphthalenes (PCNs), polychlorinated dibenzo-p-dioxins/furans (PCDD/DFs), polybrominated diphenyl ethers (PBDEs), hexabromocyclododecanes (HBCDs), perfluorinated compounds (PFCs), synthetic musks, polynuclear aromatic hydrocarbons (PAHs), and octyl- and nonylphenols
Environmental and biological matrices used for the trend studies were atmosphere, water, soil, sediment, bivalve mollusks, fish, marine mammals, terrestrial mammals, and human breast milk
Spatial and temporal trend studies presented from Australia, Brazil, China, Estonia, Ghana, Hong Kong, India, Italy, Japan, Korea, Norway, Poland, Sweden, the United States, coastal and open ocean environments, and the Arctic and Antarctic regions
POCs have been the subject of an intensive regional, national, and international effort to limit their production and use, and to mitigate the disposal of these chemicals. Since POCs are prevalent in air, water, soil, and tissues of organisms (including wildlife and humans) throughout the world and do not degrade, they cause long-term effects in organisms. Trend monitoring studies are essential to make clear the behavior and fate of these compounds and to protect our environment and living resources. Relevant to professionals and students alike, Global Contamination Trends of Persistent Organic Chemicals facilitates the understanding of environmental and biological behavior of these chemicals and the development of strategies for protecting the global environment for future generations.
amounts of contaminants. Water reclamation is an absolute necessity today because we have contaminated our surface water, and even groundwater in some cases, to a point that it is not clean enough for drinking or cooking. Most importantly, we have to use water judiciously and reclaim water that is contaminated. This book provides information on various global water challenges and solutions.
We face many water challenges in terms of availability, quality, and sustainability (Chapter 1). There is an urgent need to find ways to make water more sustainable. To achieve this objective, we will have to address scientific, technical, economic, and
social issues. Chapters 2 and 3 raise our awareness of water issues, as well as the impact of climate change. Water challenges, including sanitation issues in Central America, South America, and Africa, are covered in Chapters 4, 5, and 6. Water pollution in various rivers in India is encompassed in Chapters 7, 8, and 9. The currently implemented solutions are discussed in some detail. Water scarcity in the Middle East provides an interesting study in that part of the world (Chapter 10). The impact of firefighting foams on water in Japan is discussed at some length in Chapter 11. Overcoming the water treatment challenges in various European countries is covered in Chapters 12, 13, and 14.
Chapter 15 discusses the role of immobilized microorganisms and aggregates in wastewater treatment. Reducing the effect of drought on soil in northeast Brazil is covered in Chapter 16. Promoting biodiversity through the maintenance of healthy wetlands can provide beneficial and sustainable ecosystems; however, it can also have adverse consequences on human health (see Chapter 17 for a study in Australia). Nanotechnology solutions to global water challenges are provided in Chapter 18. As a result of their exceptional adsorptive capacity for water contaminants, grapheme based nanomaterials have emerged as a subject of significant importance in the area of membrane filtration and water treatment. Global fresh water is finite, and its supply
is severely strained by competing forces of an expanding world population on the one hand, and alterations in the water cycle as a result of climate change on the other (Chapter 19).
The two volumes are based on the successful symposium on “Status and Trends of Persistent Organic Chemicals in the Environment”. The symposium took place at PACIFICHEM 2015, International Chemical Congress of Pacific Basin Societies, December 15-20, 2015 in Honolulu, Hawaii. The symposium brought together an impressive group of leading experts in the field, covering a broad spectrum of expertise in contamination status and temporal trends of POCs from countries in the Pacific Rim. Eighteen platform presentations and nine posters were presented. The presentations created an exciting and dynamic forum for highlighting current contamination profiles and as well as future trends, which formed the foundation of this two-volume book published by the American Chemical Society.
Topics covered in Volume 1 include an overview of POCs contamination status and trends in the Pacific Basin Countries (Chapter 1); human exposure to brominated flame retardants (Chapter 2); persistent toxic substances in Vietnam (Chapter 3); dietary exposure to a variety of organohalogen pollutants and heavy metals in Tokyo, Japan (Chapter 4) and Georgia, USA (Chapter 5); e-waste and associated environmental contamination in the Asia/Pacific Region (Chapter 6), including a case study on dioxin and furan exposure to e-waste workers in India (Chapter 7); POCs in sediments (Chapter 8), soil and atmosphere of South Korea (Chapter 9); and new research on sequestration and redistribution of emerging and classical persistent organic pollutants by polystyrene (Chapter 10).
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.
