Review on the State of Air Pollution in East Asia

The “Review on the State of Air Pollution in East Asia (The RSAP)” aims at synthesizing best scientific knowledge on the present status on air pollution and its environmental impacts, focusing mainly on East Asia. It is expected to be a basis for discussions on the future development and expansion of scope for the EANET. The present status of Particulate Matter (PM) and Haze, Oxidants, and Acidification and Eutrophication, including their environmental impacts, are reviewed in Chapters 2, 3 and 4, respectively. In addition to these issues, air toxics such as Persistent Organic Pollutants (POPs) are also reviewed in Chapter 5, reflecting recent international concerns. Chapters 6 and 7 present a review of emission inventories and mitigation technology of air pollutants. Finally, a review on climate-air pollution interaction and co-benefit/co-control approaches, which have recently been raised by UNEP/WMO and for which international policy initiatives have already started, are included in Chapter 8. Prior to the above-mentioned chapters, Chapter 1 introduces an overview of the RSAP. This chapter is a brief on the status of air pollution in East Asia in the last couple of decades and its contribution to global anthropogenic air pollution. This chapter shows a total air pollution scheme identifying processes such as emissions, transport, chemical and physical transformation, cloud uptake and deposition, and includes environmental impacts and the behaviors of each pollutant in the process.
