What are Air Toxics?
Air toxics are hazardous air pollutants that have a serious negative impact on human health, like causing cancer, reproductive effects or birth defects.
The U.S. Congress amended the Clean Air Act In 1990 to allow the Environmental Protection Agency (EPA) to oversee the control of 188 hazardous air pollutants (HAPs) in order to protect human health. The EPA works with local and state governments to implement technologies that control the emission of these chemicals.
Because Houston is home to many of the largest petrochemical facilities in the U.S. and the world, Houston unfortunately has many different HAPs in our air. Of the EPA’s 188 HAPs, 161 are present in varying concentrations at different locations in the Houston area.
Air toxics like 1,3-butadiene, used to produce different kinds of rubber products such as tires, and benzene, found in gasoline, can reach annual levels many times higher than in other major U.S. cities, according to a 2006 study by Rice University (view study).
Communities that are most at risk of developing health effects from air toxics are the neighborhoods located in close proximity to petrochemical plants and refineries. These areas are called fenceline communities because they are literally in the backyard of some major industrial facilities. The Manchester community located in Houston’s East End is one of these fenceline communities.
Air Alliance Houston is working with local elected officials and regulatory agencies, as well as other environmental groups to promote new technologies that can be implemented to significantly reduce the harmful emissions of air toxics.
