Description: This geospatial dataset contains ambient concentration estimates of hazardous air pollutants for the 2014 National Air Toxics Assessment (NATA). The dataset contains concentration estimates at the census tract level for all pollutants modeled for NATA. The census tract shapes and attributes are from a dataset published by ESRI in 2013 for the year 2010. The concentration estimates are based on air quality and dispersion modeling of emissions from the 2014 National Emissions Inventory (NEI).
