Fine particulate matter results from natural sources and transportation, study shows

Research funded by the Asphalt Institute determines that, in the Dallas-Fort Worth metropolitan area, the dominant sources of fine particulate matter known as PM2.5 are from natural sources and transportation.

Fine particulate matter (PM2.5) is a potential air pollutant regulated at Dallas-Fort Worth (DFW) facilities, including asphalt facilities. PM2.5 is regulated based on research showing potential contribution to juvenile asthma and other lung-related health effects. PM2.5 emissions at an asphalt facility in the DFW area are stringently regulated by the Texas Commission on Environmental Quality (TCEQ) or the City of Dallas. Even though the sources are regulated, and PM2.5 emissions are limited by control technology required by the permit, local environmental groups have caused unwarranted public scrutiny to force the closure of asphalt facilities in the DFW area based on their potential PM2.5 and other emissions.
