Analysis of air-toxics emissions, exposures, cancer risks, and controllability in five urban areas. Volume 1. Base year analysis and results
This report is the first phase of a study to define the multiple-source, multiple pollutant nature of the urban air-toxics problem (also known as 'urban soup') and to discern what control measures (or combinations of measures) can best be employed to mitigate the urban air-toxics problem. The report documents the base year analysis, involving dispersion modeling of emissions data for 25 carcinogenic air toxics in five U.S. urban areas and a subsequent exposure/risk assessment to estimate aggregate cancer incidence. Aggregate (multi-source, multi-pollutant) cancer incidence (or population risk) across the 5 cities in this study averaged about 6 excess cases per million persons, ranging from about 2 to 10 in individual cities. The most-important pollutants contributing to aggregate incidence are polycyclic organic matter, 1,3-butadiene, formaldehyde and hexavalent chromium. The most-important sources are road vehicles, comfort and industrial cooling towers, chrome platers, solvent use, and fuel combustion, including wood stoves.
