The Arctic is a vital region that helps preserve the balance of the global climate. The Arctic environment is particularly sensitive to short-lived climate pollutants, including black carbon, due to their strong warming effect. With ambitious policy action to reduce air pollutants, Arctic Council countries would obtain a positive effect on health and the environment throughout their territory, while also helping to slow down climate change by reducing emissions of black carbon. This report calls for ambitious policy action to reduce air pollution in Arctic Council countries, highlighting the environmental, health, and economic benefits from policy action.

A variety of air pollutants are emitted into the atmosphere from human-caused and natural emissions sources throughout the United States and elsewhere. These contaminants impact sensitive natural resources in wilderness, including the national parks. The system of national parks in the United States is among our greatest assets. This book provides a compilation and synthesis of current scientific understanding regarding the causes and effects of these pollutants within national park lands. It describes pollutant emissions, deposition, and exposures; it identifies the critical (tipping point) loads of pollutant deposition at which adverse impacts are manifested.

th Towards the end of the 19 century some researchers put forward the hypothesis that the Polar regions may play the key role in the shaping of the global climate. This supposition found its full confirmation in empirical and th model research conducted in the 20 century, particularly in recent decades. The intensification of the global warming after about 1975 brought into focus the physical causes of this phenomenon. The first climatic models created at that time, and the analyses of long observation series consistently showed that the Polar regions are the most sensitive to climatic changes. This aroused the interest of numerous researchers, who thought that the examination of the proc esses taking place in these regions might help to determine the mechanisms responsible for the "working" of the global climatic system. To date, a great number of publications on this issue have been published. However, as a re view of the literature shows, there is not a single monograph which comprises the basic information concerning the current state of the Arctic climate. The last study to discuss the climate of the Arctic in any depth was published in 1970 (Climates a/the Polar Regions, vol. 14, ed. S. Orvig) by the World Survey of Climatology, edited by H. E. Landsberg. This publication, however, does not provide the full climatic picture of many meteorological elements.

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.

An important purpose of The Handbook of Environmental Chemistry is to aid the understanding of distribution and chemical reaction processes which occur in the environment. Volume 4, Part B of this series is dedicated to Air Pollution Control Equipment, Materials Damage, Peroxyacyl Nitrates, Semivolatile Compounds in the Atmosphere, and Arctic Haze.

“A slender but punch-packing overview of the environmental destruction of the Far North” from the award-winning environmental reporter (Kirkus Reviews). Traditionally thought of as the last great unspoiled territory on Earth, the Arctic is in reality home to some of the most severe contamination on the planet. Awarded a major grant by the Pew Charitable Trusts to study the Arctic’s deteriorating environment, Los Angeles Times environmental reporter Marla Cone traveled across the Far North, from Greenland to the Aleutian Islands, to find out why the Arctic has become so toxic. Silent Snow is not only a scientific journey, but a personal one with experiences that range from tracking endangered polar bears in Norway to hunting giant bowhead whales with native Alaskans struggling to protect their livelihood. Through it all, Cone reports with heartbreaking immediacy on the dangers of pollution to native peoples and ecosystems, how Arctic cultures are adapting to this pollution, and what solutions will prevent the crisis from getting worse.
