Why is the DEARS important to understanding air quality?
The study is contributing to our understanding of how air quality information collected at the community level compares to actual human exposures. This is accomplished by comparing air quality measurements taken at a centrally located community monitoring site to data collected in neighborhoods, in and around individual homes, as well as, to personal exposure measurements. Additionally, by completing questionnaires and surveys, the DEARS participants provided EPA scientists with a better understanding of the activities that affect individuals exposures to air pollutants. Ultimately what scientists learn from the DEARS will help EPA, and others protect human health and the environment.
