Persistent Organic Pollutants (POPs) continue to be the subject of concern amongst the public, as well as the scientific and policy-making communities. These concerns are exemplified by the international efforts co-ordinated by the United Nations' Environment Programme and the +Economic Commission for Europe. Whilst the ultimate origin of this concern is the adverse effects of persistent organic pollutants in both humans and wildlife, there are other factors involved. In particular, whilst ambient concentrations of POPs in air and water present little direct hazard via inhalation and ingestion respectively, their propensity for transfer through the food chain means that species at the top of the ecological pyramid - including humans - can be exposed to concentrations of concern via their diet. Furthermore, their ability to undergo long-range atmospheric transport means that they represent a truly cross-boundary problem for mankind. Persistent Organic Pollutants focuses on the sources, atmospheric behaviour, terrestrial and aquatic food chain transfer, and human exposure and fate aspects of this important class of chemicals. Other topical issues are addressed, namely: temporal trends in contamination; their transport to polar regions; and the significance of the former Warsaw Pact nations of Central and Eastern Europe as both a global reservoir and source of POPs. Whilst the main focus is on PCDD/Fs, PCBs, and PAH; other organochlorine POPs such as DDT, lindane, and dieldrin are covered. Persistent Organic Pollutants also provides up-to-date, detailed, and authoritative coverage required by academics, environmental consultants, and policy-makers. Sufficient introductory material is also included to be of relevance to final year undergraduates, Masters and PhD students in Environmental Science/Chemistry.

Since the mid 1990s, legal action to eliminate persistent organic pollutants (POPs) has started resulting in a global Convention on POPs, the Stockholm Convention, and a regional Protocol under the Convention on Long-Range Transboundary Air Pollution (UN-ECE LRTAP Convention). POPs are characterized by long half-lives, persistence in the environment, they undergo long-range transport, accumulate in the environment and in biota, and they are toxic. The combination of these characteristics makes them a threat at the global level. This book makes the reader familiar with the goals of these two conventions, lays out characteristics of these compounds, presents results from case studies and addresses inventories, levels in humans and the environment as well as technologies to destroy them.

A variety of chemical compounds has been released into water from industrial and agricultural activities and urban wastes. Some of those chemicals are harmful to living organisms and are resistant to degradation, thus named persistent organic pollutants (POPs). In efforts to manage chemical pollutants such as POPs in Asia, the United Nations University (UNU) and Shimadzu Corporation established a pilot project in 1996, “Environmental Monitoring and Analysis in the East Asian Region”, to aid developing Asian countries with the knowledge and technology to analyse and monitor such pollutants in the environment. This book summarizes some highlights of monitoring results obtained by the project’s activities for 15 years, and reports the present status of the project, touching on the future development of the project by analysing challenges ahead of the project.

Persistent organic pollutants (POPs) are organic compounds that remain intact in the environment for long periods, become widely distributed geographically, accumulate in the fatty tissue of living organisms and are toxic to humans and wildlife. The Stockholm Convention on POPs is a global treaty to protect human health and the environment from POPs which came into force in 2004. Currently, twelve substances or substance groups are included under the Stockholm Convention, but there is a case for including new and emerging POPs such as brominated flame retardants and perfluorinated substances. This book considers these two new pollutants, together with the emerging area of chirality and its applications as an environmental forensics tool, and the topic of POPs contamination of indoor environments.

Persistent organic contaminants, which are bioaccumulative and toxic are a concern for the ecosystems and human health and are regulated under international law (global and regional conventions, besides other). If semivolatile, they cycle in different environmental compartments and follow complex transport pathways. The ocean is believed to play a key role in the cycling by accumulating and storing the contaminant and providing a transport medium. But substance fate in the marine environment is not fully understood yet. Here, the global multicompartment chemistry-transport model MPI-MCTM is used to study the fate of organic pollutants in the marine and total environment. For the first time historical emission data are used in spatially-resolved long-term simulations of an insecticide, DDT, and an industrial chemical, perfluorooctanoic acid (PFOA). The model results give new insights into the cycling of these substances as different spatial and process resolutions were tested. E.g. for DDT the model results show saturation and reversal of air-sea exchange, which was not indicated by any other study before.
