RECENT EVIDENCE ON THE DISTRIBUTION OF AIR POLLUTION EFFECTS

This study associates levels of exposure to ozone and fine particulate matter in the South Coast Air Basin of California with resident income, race, age and education. A Regional Human Exposure Model provides the basis for estimating exposure not only on location or residence, but also on mobility within the Basin and time spent in various activities indoors and outdoors. The results are consonant with earlier research in most respects, except that population density is negatively related to exposure. Ethnic minorities and children receive the greatest exposure levels. The highest income group exhibits a strongly negative association with exposure.
