Book Description
Persistent organic pollutants (POPs), which include PCBs, DDTs, chlordane, dieldrin, and dioxins, are responsible for a large majority of the failures of Estuary waters to meet water quality standards. The San Francisco Estuary Institute (SFEI) has monitored Estuary water, sediments, bivalves, and fish since 1993. We have combined these data with simple mass balance models to develop a general conceptual model that illustrates the major factors controlling the environmental fate of these POPs and another group of organic contaminants, polycyclic aromatic hydrocarbons (PAHs).

Persistent Organic Pollutants (POPs): Analytical Techniques, Environmental Fate and Biological Effects
Author:
Publisher: Elsevier
ISBN: 0444633006
Category : Science
Languages : en
Pages : 685
Book Description
This book focuses on those organic chemicals that are regulated by the Stockholm Convention on Persistent Organic Pollutants (POPs). as well as organic chemical with the attributes of being persistent, bioaccumulative, and toxic to ecosystem and human beings, criteria used by the Stockholm Convention for screening POP candidates. Because of the unfavourable properties of POPs, numerous research efforts have been directed toward investigating their input sources, fate, and effects, with the help of continuously improving analytical technologies. The contributors to this book provide an integrated assessment of existing data, which will benefit both the scientific and management communities in planning further research projects and/or pollution control measures. Comprehensive overview of recent advances in analyzing persistent organic pollutants (POPs) Covers input sources, fate and biological effects of POPs Contains essential information for environmental management

Modelling the Sources, Fate and Environmental Behaviour of Persistent Organic Pollutants
Environmental Fate of Persistent Organic Pollutants in Lake Thun, Switzerland
The Role of the Ocean in Global Cycling of Persistent Organic Contaminants
Author: Irene Stemmler
Publisher: Springer Science & Business Media
ISBN: 3642050093
Category : Science
Languages : en
Pages : 107
Book Description
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.

Persistent Organic Pollutants

Category : Technology & Engineering
Languages : en
Pages : 468
Book Description
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.

Global Sources of Local Pollution
Author: National Research Council
Publisher: National Academies Press
ISBN: 0309144019
Category : Nature
Languages : en
Pages : 248
Book Description
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.
