Available in PDF, EPUB and Kindle. Book excerpt: Northern Lights Against POPs tells the many-faceted scientific, policy, legal, and advocacy story that led to the Stockholm convention. Unique in its perspective, scope, and breadth, it reveals the key links among environmental and health science, international politics, advocacy, law, and global negotiations. Never before have public health concerns articulated by northern Indigenous peoples in Canada and throughout the circumpolar Arctic had such a direct impact on global policy-making. Authors show how research on POPs (persistent organic pollutants) in the Arctic from the mid-1980s influenced international negotiations and analyze the potential for the convention to be effective. Contributors include elected representatives, researchers, civil servants, Indigenous people who participated in the negotiations, and scientists who provided the compelling Arctic data that prompted the United Nations Environment Programme to sponsor negotiations. Contributors include David Anderson (Minister of the Environment, Canada); Nigel Bankes (University of Calgary); John Buccini (Consultant, former chair of the Global POPs Negotiations); Sheila Watt-Cloutier (Inuit Circumpolar Conference-Canada); Barry Commoner, Paul Woods Bartlett, Holger Eisl, Kimberly Couchot (Center for the Biology of Natural Systems, Queens College, City University of New York); Eric Dewailly (Laval University); David Downie (Director of Educational Partnerships, Columbia Earth Institute, Columbia University, New York); Terry Fenge (Inuit Circumpolar Conference-Canada); Henry Huntington (Consultant, Anchorage) and Michelle Sparck (Circumpolar Conservation Union, Washington, D.C.); Harriet Kuhnlein, Laurie Chan (Centre for Indigenous Peoples' Nutrition and Environment, McGill University), and Olivier Receveur (formerly Centre for Indigenous Peoples' Nutrition and Environment, McGill University); Lars-Otto Reiersen (Arctic Monitoring and Assessment Programme Secretariat,Oslo); Henrik Selin (Massachusetts Institute of Technology); David Stone, Russell Shearer (Northern Contaminants Program, Department of Indian Affairs and Northern Development, Canada); Klaus Topfer (Executive Director, United Nations Environment Programme).

Available in PDF, EPUB and Kindle. Book excerpt: Recent advances in air pollution monitoring and modeling capabilities have made it possible to show that air pollution can be transported long distances and that adverse impacts of emitted pollutants cannot be confined to one country or even one continent. Pollutants from traffic, cooking stoves, and factories emitted half a world away can make the air we inhale today more hazardous for our health. The relative importance of this "imported" pollution is likely to increase, as emissions in developing countries grow, and air quality standards in industrial countries are tightened. Global Sources of Local Pollution examines the impact of the long-range transport of four key air pollutants (ozone, particulate matter, mercury, and persistent organic pollutants) on air quality and pollutant deposition in the United States. It also explores the environmental impacts of U.S. emissions on other parts of the world. The book recommends that the United States work with the international community to develop an integrated system for determining pollution sources and impacts and to design effective response strategies. This book will be useful to international, federal, state, and local policy makers responsible for understanding and managing air pollution and its impacts on human health and well-being.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2010-03-10 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2014 with total page 365 pages. Available in PDF, EPUB and Kindle. Book excerpt: Humanity is currently using more than 200000 synthetic organic compounds in many industrial, agricultural and domestic applications. Many of these chemicals reach the environment and have a harmful effect on ecosystems and humans. Among them, the group of persistent organic pollutants (POPs) comprises several families of compounds that have physical and chemical properties that give them the ability to be distributed and impact globally (semivolatility, high persistence and bioaccumulation capacity due to their hydrophobicity). In the present thesis, the coupling of atmospheric transport and biogeochemical cycles in the Arctic and Southern Ocean has been studied for Hexachlorocyclohexanes (HCHs), Hexachlorobenzene (HCB) and Polychlorinated Biphenyls (PCBs). Three oceanographic cruises were conducted, one in the North Atlantic and the Arctic Ocean (2007) and two in the Southern Ocean surrounding the Antarctic Peninsula (2008 and 2009). During these campaigns, air (gas and particulate), water (dissolved and particulate) and biota (phytoplankton) were sampled simultaneously allowing to report a complete picture of POPs cycling in polar areas. In the case of the Southern Ocean, the largest data set available for PCBs, HCH and HCB has been generated. The atmospheric and seawater concentrations were low, among the lowest reported for the Polar Oceans, and in the case of the Southern Ocean there is a clear historical trend of decreasing concentrations, consistent with reduced emissions in source regions. Long range atmospheric transport was identified as the main POPs input to polar ecosystems agreeing with previous works. However, it has been found that secondary local sources from soil and snow influences strongly the atmospheric concentrations overland in the Antarctic region, and over the adjacent Southern ocean in the case of HCHs. Atmospheric residence times calculated from the measurements were in agreement with the prediction from environmental fate models. The atmospheric residence times were longer for the less hydrophobic PCBs and shorter for the more hydrophobic, consistent with the role of the biological pump sequestering atmospheric PCBs. Once POPs reach the Polar regions the main route of entry of these compounds to surface waters is by atmospheric deposition, mainly by diffusive exchange between the gas and dissolved phase with minor contributions from dry deposition of aerosol bound POPs. Estimated bioconcentration factors revealed that concentration of POPs in phytoplankton were correlated with the chemical hydrophobicity, but some discrepancies with model predictions were observed. The biological and degradative pumps are identified as the two main processes that control the fate and occurrence of POPs in the surface water column, and also are able to modulate the atmospheric transport of POPs to remote areas. POPs such HCHs are prone to be efficiently degraded by bacterial communities in surface waters, depleting the seawater concentrations and increasing the diffusive air-water exchange to the Arctic and Southern Ocean. Conversely, the biological pump decreases the dissolved phase concentrations of the more hydrophobic PCB congeners increasing the air to water fugacity gradients and enhancing the diffusive air-water exchange fluxes. This is the first time that the influence of the biological pump on POP cycling is demonstrated for Oceanic waters. Finally, HCB was close to air-water equilibrium showing that neither the biological and degradative pumps are efficient sequestration processes for the highly persistent and mid-hydrophobic compounds. Overall, the results show clearly that biogeochemical processes occurring in the water column affect the atmospheric deposition and long range transport of POPs to remote regions.The magnitude of these processes may show a clear seasonality and are suitable to be perturbed under the current scenario of climate change.

Available in PDF, EPUB and Kindle. Book excerpt: This book addressed an in-depth comprehension of the classifications and characterizations of POPs, which have become global issues due to bioaccumulation, persistency, and toxicity. It represents the milestones of the development of pesticide application, industry, and management. Banned SC-POPs have special investigations. It discusses air-sea exchange, ocean currents, phase distribution, speciation, adsorption, desorption, and degradation as the key processes that control POP's fate. The book explores several aspects of POP chemistry that have a direct influence on their biochemical and toxicological consequences. The book illustrates the dynamic equilibriums influencing the proportion of a POP's gaseous, liquid, and solid phases. The book discussed POP migration by referring to the grasshopper effect. It also explores the impacts of climate change on emissions and the fate of POPs through a global-scale multimedia fate model. Additionally, it displays the impact of potential global change scenarios on POP bioaccumulation patterns. The book is directed at giving a deep discussion of the method's QA/QC process for POP determination and has verified the accuracy and precision of the procedures. As a distinctive point, it discusses many aspects concerning the toxicity of POPs. It reports mechanisms describing the toxicity of POPs on immune systems, carcinogenesis, endocrine, neural, and reproductive systems. The book keeps an eye on a model describing the global distribution and toxicity of PAHs. Among the exclusive points in the book is the evaluation of the recent ecological status in Egypt relative to POPs through a time-scale overview and recent case studies. It provides thematic literature related to DDC research in Africa through the WoS and Scopus databases from 1949 to 2021. The book emphasizes models for predicting the annual contribution rate of POPs as a way to raise public awareness about POPs. The greatest challenge for the book is how to motivate the audience to be aware of these hazardous materials in marine ecosystems. Moreover, this book will be of great interest to academics, professionals, practitioners, post-graduate students, and undergraduates because it gives a clear overview of POPs in the marine environment. It also provides decision-makers with a realistic perspective of the environmental file, allowing them to address environmental issues and directing stockholders to safer locations for environmental activity. From a future perspective, the regulation of pervasive POPs, with special reference to recently evaluated harmful substances (PFASs), has faced significant challenges in the wake of pressure from regulators.

This book was released on 2004 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: Monitoring is recognized as an essential tool for identifying status and spatial and temporal trends of persistent organic pollutant (POPs) in the atmosphere. To investigate the origin and long-range transport behavior of POPs in air, a novel passive air sampler (PAS) was developed based on the polystyrene/divinylbenzene co-polymeric resin XAD. The PAS was characterized by sorption measurements of chlorobenzenes onto XAD at various temperatures, wind tunnel experiments and computer simulations of the uptake kinetics, and field calibration experiments under Arctic and temperate conditions. The performance of this PAS was evaluated by comparing PAS-derived concentrations with those measured by conventional HiVol samplers. These studies demonstrated the usefulness of XAD-based PAS for atmospheric POP monitoring. A PAS network was established across North America, consisting of 40 stations covering 72 degrees of latitude (10° to 82°N) from the Arctic to Costa Rica and 72 degrees of longitude (53° to 125°W) from Newfoundland to Vancouver Island. Four of these stations constituted an altitudinal transect in the southern Canadian Rocky Mountains, covering an elevational range of more than 1500m. Annually averaged air concentrations of organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), and polybrominated diphenyl ethers (PBDEs) were determined in 2000/2001 at these stations, as was the enantiomeric composition of chiral OCPs. The distribution patterns of the POPs were found to depend on their physical-chemical properties, their emission history, and the environmental conditions. Evidence for global fractionation along latitude and altitude was observed. Multivariate statistical analysis allowed for a better understanding of the observed composition patterns of PCBs and PBDEs. Estimation of the long range transport potential of OCPs, empirically from network concentrations, and theoretically from model calculations yielded a comparable classification. In order to have consistent input data for these model simulations, a complete set of partitioning properties (aqueous solubility, octanol-water partition coefficient, vapor pressure, Henry's law constant, octanol-air partition coefficient) for fourteen OCPs was derived by compiling, evaluating, selecting, and adjusting all measured values reported in the literature. Large scale PAS networks are suitable for monitoring compliance with, and effectiveness of, regulatory control measures, and for establishing experimentally the atmospheric long-range transport behavior of POPs.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
