Land use policies and practices in urban areas, including zoning, facility siting and built environment features more generally, play a role in neighborhood-level exposures to hazardous air pollutants or air toxics. Urban air toxics are suspected of contributing to adverse health outcomes including asthma, low birth weight, and cancer. However, few cities have networks of street-level hazardous air pollutant monitoring, limiting the ability of community members and environmental health professionals from making informed intervention decisions. This paper suggests that land use information can act as a proxy for air toxics monitoring data. Using a set of publicly available data that provide detailed information on point sources from facility location, size, and chemical use, mobile source contributions from truck routes and intersection traffic counts, and area sources from manufacturing land use data, we develop a dispersion model of air toxics using GIS spatial analytic tools across New York City neighborhoods. Our land use-air toxics model builds on the National Air Toxics Assessment, but improves these modeled data by including neighborhood specific inputs that allow for census-tract level analyses - - a key limitation of the NATA data for most urban areas. The paper describes the importance of land use data for understanding air toxic exposures, especially in the absence of monitoring data, how urban planners and public health professionals can use readily available land use data to estimate air toxic hazards at the census-tract level, and offers policy recommendations for analyzing the built environment and air toxics in urban neighborhoods.
