The U.S. Environmental Protection Agency National Air Toxics Assessment is an
evaluation of 178 high priority toxic air pollutants. This assessment gives DEQ
a better understanding of the air toxics problem in Oregon. The assessment helps
DEQ target areas of the state for developing more detailed information and air
toxics reduction strategies.
What is the National Air Toxics Assessment?
This assessment includes three types of information:
- an updated national air toxics emissions inventory
- computer modeling estimates of air pollutant concentrations
- estimates of people’s exposure to these pollutants
