Reducing Exposure to Airborne Chemical Toxics (REACT)

The Reducing Exposure to Airborne Chemical Toxics (REACT) study is a comprehensive air toxics study to measure levels of toxic air pollutants in the Memphis area that is funded by the U.S. Environmental Protection Agency. This study will examine and compare health risk and air quality across different communities throughout Shelby County by conducting acute (short-term) air sampling and analysis over a one-year period.  The study is a collaboration between Shelby County Health Department, the University of Memphis, and Middle Tennessee State University.

We would like to invite residents to participate in the study as a representative of your neighborhood.  When the study is completed, we will have a better understanding of the concentrations, sources, and potential health effects of air toxics in Shelby County.  Copies of the study report will be available upon request when completed.

What does it require of residents?

-          A secured (e.g., fenced) backyard.  The device sits on a tripod and is approximately 6 feet 
       tall (see REACT Flyer below for more information). 

-          Field Staff will conduct air sampling in the back yard four times (Fall, Winter, Spring, 
       Summer) during a one-year time period (Residents will not be disturbed.) Pets must be
       secured during the visits to allow field staff access to the monitoring location.  Field staff
       will set up the device one day prior to each 24-hour monitoring period and then return to
       pick up the device the following day.

-         There are no costs associated with taking part in the study

If you are interested in participating in this study, please send your contact information, including your name, home address, telephone, and e-mail to Dr. Chunrong Jia at .
