The EPA identified 68 area source categories of urban air toxics. Health effects of urban air toxics. Air toxics tend to pose greater risks in urban areas because these areas have large populations and a higher concentration of emission sources. Combined exposures from all sources of air pollution, including major stationary sources, smaller area sources, indoor sources and mobile sources can increase public health risks from air toxics. National Air Toxics Program: The Integrated Urban Strategy Report to Congress. 15The sum of hazard quotients (HQs) for multiple chemicals where the HQ is the ratio of a level of exposure for a single substance to a reference level (e.g., a reference concentration) for that chemical derived from a single exposure.   Reducing emissions of urban air toxics has been a priority for EPA since the passage of the Clean Air Act Amendments in In the last two decades we've seen significant reductions in urban air toxics as a result of EPA regulations and enforcement actions, as well as the implementation of state and local programs to address emissions from both mobile and stationary sources. National Air Toxics Program The Integrated Urban Strategy Report to Congress 6‐12 long‐term effect of exposure to a carcinogen. Further work in the Office of Research and Development examined the role of tolerance as a factor that could reduce the impact of acute VOC exposure.

On Aug , the U.S. Environmental Protection Agency (EPA) released the Second Integrated Urban Air Toxics Report to Congress - the final of two reports required under the Clean Air Act (CAA) to inform Congress of EPA’s actions and progress in reducing public health risks from urban air toxics.; Using national emissions and air quality data, the report shows the substantial progress. Measurement and Modeling of Exposure to Selected Air Toxics for Health Effects Studies and Verification by Biomarkers EPA Grant Number: RC Subproject: this is subproject number , established and managed by the Center Director under grant R (EPA does not fund or establish subprojects; EPA awards and manages the overall grant for this center).

Reports describing prior OAQPS applications of the pNEM to carbon monoxide and ozone are available. APEX serves as the human inhalation exposure model within the Total Risk Integrated Methodology (TRIM) model .
