Sources and emissions of fugitive particulate matter
Additional Document Info
2017 by Nova Science Publishers, Inc. There are substantial evidences that airborne particulate matter (PM) contribute to haze, acid rain, global climate change, asthma and other respiratory ailments, cardiopulmonary disease, and decreased life expectancy. Most common sources of airborne PM (primary or secondary) are of natural (e.g., desert sand, sea spray, pollen) and anthropogenic (e.g., vehicles, industry) origin. Not much can be done to control the former sources, but a lot of efforts have been put forward to control the anthropogenic PM emissions via advanced air pollution control methods (e.g., cyclones, filters). However, many recent studies have reported that a large fraction of airborne PM could be attributed to fugitive PM, in other words, PM that is caused by wind shear, material transfer processes or other mechanical processes such as agriculture, road traffic, construction and industrial activities. This chapter discusses the main sources of fugitive PM (fPM), presents state-of-the-art methods for the calculation of their emissions, and concludes with a brief review of fPM health effects.
