Scientists at the National Institute of Environmental Health Sciences (NIEHS) conducted research on the effects long-term exposure to air pollutants has on the health and found it increases the risk of respiratory illnesses such as allergies, asthma, chronic obstructive pulmonary disease, and lung cancer. Children and the elderly are particularly vulnerable to the health effects of ozone, fine particles, and other airborne toxicants. As a result of this research, more stringent air quality standards have been put in place that promote a higher quality of life, protect the health of children, the elderly and other vulnerable populations, and reduce the costs associated with respiratory disease.
