Researchers have long linked asthma — a serious and life threatening chronic respiratory disease that affects the quality of life of more than 23 million Americans — with exposure to air pollution. Air pollution can make asthma symptoms worse and trigger asthma attacks. The estimated six million children in the United States with asthma are especially vulnerable to air pollution.
The Environmental Protection Agency (EPA) studies the link between air pollution and asthma so that action can be taken to reduce the health burden associated with the disease. Childhood asthma research at the EPA covers a variety of topics including the impact of certain air pollutants on asthma, how exposure to air pollution may contribute to asthma, and which children may be particularly vulnerable.
