Abstract
Air toxics, defined as pollutants known to cause, or that are suspected of causing, cancer or other serious health effects, are emerging as an issue for transportation planners. Air toxics from highway vehicles and nonroad equipment, including aircraft, locomotives, marine vessels, and construction machinery, contribute significantly to the risk of cancer and other health problems. This article presents a guide to air toxics, exposure research, and related federal controls, and outlines strategies that can be applied readily at the local level. (Author/publisher)
