2011 NATA (National Air Toxics Assessment): Assessment Results

This page provides the inventory inputs, ambient and exposure concentrations, and results for the 2011 National-scale Air Toxics Assessments. The starting point for the 2011 NATA inventory was the 2011 National Emissions Inventory. There are also links to supporting files and web pages. EPA suggests that the results of this assessment be used cautiously, as the overall quality and uncertainties of the assessment will vary from location to location as well as from pollutant to pollutant. In many cases more localized assessments, including monitoring and modeling, may be needed to better characterize local-level risk.
