WASHINGTON–(ENEWSPF)–March 7, 2011. The U.S. Environmental Protection Agency has awarded $32 million to fund four new Clean Air Research Centers at universities conducting cutting edge air pollution research. The research will focus on the impacts of air pollution mixtures on people’s health. It is important to understand the health risks associated with exposure to multiple air pollutants because people are exposed to more than one pollutant at a time.
