TRANSPORTATION-RELATED AIR QUALITY. IN: HANDBOOK OF TRANSPORTATION ENGINEERING
This chapter describes how air pollution is the presence of undesirable material in the air in sufficient quantities to pose health risks to humans, damage vegetation, negatively impact ecological systems, reduce visibility, or damage property. A number of naturally occurring processes contribute to air pollution, such as dust, forest fires, and volcanoes. In urban area, the majority of pollution originates from human activity and includes stationary sources, such as factories or power plants; area sources including facilities such as dry cleaners; and mobile sources. Mobile sources include automobiles, trucks, buses, aircraft, trains, marine activity, farming equipment, construction equipment, lawn mowers, etc. Mobile sources contribute approximately 60 percent of carbon monoxide (CO), 50 percent of nitrogen oxides (NOx) and 40 percent of volatile organic compounds (VOC) in urban areas, the majority of which is attributed to highway vehicles. In certain urban areas, CO emissions from mobile sources have been estimated as high as 95 percent.
