tailieunhanh - Principles and Practices of Air Pollution Control: Student Manual

Fossil fuel combustion for transportation contributes to air pollution, and air pollution degrades human health. However, the path from transportation to human health costs is anything but straightforward. Which pollutants are produced in which proportions depend on a number of factors, including the vehicle and fuel used and the driving conditions of a particular trip. These emissions are dispersed into the ambient air according to atmospheric conditions, which also influence the extent to which they react to form secondary pollutants. The degree to which people may be exposed to these primary or secondary pollutants depends on. | United States Environmental Protection Agency Air Pollution Training Institute APTI Environmental Research Center MD E142-01 Research Triangle Park NC 27711 July 2003 Principles and Practices of Air Pollution Control Student Manual APTI Course 452 Third Edition United States Air Pollution Training Institute APTI April 2003 Environmental Protection Agency Environmental Research Center MD E142-01 Research Triangle Park NC 27711 Air 2 Principles and Practices of Air Pollution Control vpRơrc3 Student Manual APTI Course 452 Second Edition Authors Dr. William Franek PhD PE Mr. Lou DeRose .
