The extent of human exposure to pollutants released from industrial facilities or the health outcomes of potential exposure have rarely been investigated. This paper addresses these limitations by using a new and more accurate indicator of air pollution exposure from industrial toxic emissions reported in the U.S. Environmental Protection Agency (USEPA)’s Toxic Release Inventory (TRI) database. The specific objective is to examine racial/ethnic and socioeconomic disparities in the distribution of potential exposure to industrial air pollution in Hillsborough County, Florida, located in the Tampa Bay metropolitan area. Industrial pollution sources considered in this study are facilities reporting air emissions to the TRI database in 2000. The pollution data is derived from the USEPA’s Risk-Screening Environmental Indicator (RSEI) model, which provides information on potential human health outcomes from air pollutants by including detailed data on the toxicity and dispersion of chemical releases from TRI facilities. Square grids (1 km by 1 km) from the RSEI model are spatially overlaid and statistically related to relevant variables from the US Census 2000 to determine disparities associated with toxic pollution exposure. The results indicate that although non-Hispanic Black and Hispanic populations reside in different parts of the metropolitan area, both groups are disproportionately burdened in terms of the density of TRI facilities and level of risk from toxic exposure.
