In the last decades, concern has been raised regarding the use of polybrominated diphenyl ethers (PBDEs) due to its increased environmental occurrence and its possible toxicological impact in humans and wildlife. As a result, two of the commercial PBDE products have recently been banned within the EU, while the use of the third product (DecaBDE) is still approved. A dynamic, fugacity-based, regional multimedia fate and transport model (POPCYCLING-Baltic) has been used to assess the historical behaviour and the potential future fate of polybrominated diphenyl ethers (PBDEs), exemplifying different emission scenarios following the introduction of restricting measures. The past, current and future consumption and emission of PBDEs were estimated, and the environmental fate of individual compounds was modelled. The possible impact on the Arctic region is also discussed. Uncertainties in the estimates and data gaps were identified

Persistent Organic Pollutants (POPs) are toxic, resistant to degradation, bioaccumulative, and display wide spatial distribution. They accumulate in humans and wildlife, and have been linked to cancer, as well as reproductive and immunological disorders. In 2001 a global treaty on POPs was agreed, to minimise and ultimately eliminate the release of POPs into the environment. The Stockholm Convention lists 12 groups of chemicals, and as of late 2008, a further 12 chemicals are under consideration for inclusion. This book addresses all of these chemicals, but focuses particularly on currently listed POPs that are still of major concern (e.g. polychlorinated biphenyls - PCBs), as well as new and emerging POPs that have been the subject of an explosion of scientific interest in the last decade, i.e. brominated flame retardants (BFRs) and perfluorinated chemicals (PFCs). Other chapters address the challenges posed by the presence of POPs in the developing world; how the properties of chiral POPs can provide unique insights into their environmental sources, fate and behaviour; and issues arising from the presence of POPs in urban and indoor environments. Persistent Organic Pollutants provides a much-anticipated reference source for a wide audience including academics, industrial scientists and regulators.

The proposed book features a systematic and thorough treatment of the dominant persistent organic pollutants (POP's) encountered in the tropical marine environment of the Indian Sundarban mangrove wetlands, a UNESCO World Heritage Site. Chapters provide a comprehensive and realistic account of the world’s most hazardous organic compounds. Readers will discover a detailed account of the characteristics, potential point and non-point sources, analytical techniques and the ecotoxicological relevance of selected POPs, namely organochlorine pesticides, polychlorinated phenyls (PCBs), and polycyclic aromatic hydrocarbons (PAHs). These pollutants are of considerable interest because their exposure could cause immunologic, teratogenic and neurological problems in humans and other living beings. The book is intended to serve as a reliable and up-to-date reference source for students, teachers and researchers engaged in the field of chemical oceanography, ecotoxicology and pollution management.

Vols. for 1963- include as pt. 2 of the Jan. issue: Medical subject headings.

This book addresses the multidisciplinary challenges in biodiversity conservation with a focus on wildlife crime and how forensic tools can be applied to protect species and preserve ecosystems. Illustrated by numerous case studies covering different geographical regions and species the book introduces to the fundamentals of biodiversity conflicts, outlines the unique challenges of wildlife crime scenes and reviews latest techniques in environmental forensics, such as DNA metagenomics. In addition, the volume explores the socio-economic perspective of biodiversity protection and provides an overview of national and international conservation laws. The field of conservation medicine stresses the importance of recognizing that human health, animal health, and ecosystem health are inextricably interdependent and the book serves as important contribution towards achieving the UN Sustainable Developmental Goals, in particular SDG 15, Life on Land. The book addresses graduate students, scientists and veterinary professionals working in wildlife research and conservation biology.

Persistent Organic Pollutants (POPs) are chemicals that resist environmental degradation and cause deleterious effects on the environment and human wellbeing. Once released into the environment they can travel long distances and persist for longer duration. This book highlights the complex area of POPs in simple language and deals with the fundamentals of the chemicals, their sources, and impacts on human health. The book also unfolds several other aspects like new and advanced analytical detection methods, gaps in management, effectiveness of the Stockholm convention, and the role of the global monitoring plan on POPs for crucial and holistic understanding about POPs. It also investigates how to minimize the impact of POPs and the major gaps and challenges in sound management of POPs. With its comprehensive approach, this book is an indispensable source of knowledge for those studying and working to mitigate the effect of POPs in the environment.

The human footprint on the global environment now touches every corner of the world. This book explores the myriad ways that environmental archives can be used to study the distribution and long-term trajectories of chemical contaminants. The volume first focuses on reviews that examine the integrity of the historic record, including factors related to hydrology, post-depositional diffusion, and mixing processes. This is followed by a series of chapters dealing with the diverse archives and methodologies available for long-term studies of environmental pollution, such as the use of sediments, ice cores, sclerochronology, and museum specimens.
