The US Environmental Protection AGency (EPA) awarded $3.6 million in four grants to universities to research the relationship between the chemical composition of particulate matter (PM) and health effects. PM is a complex mixture that consists of direct emissions and reaction products formed in the atmosphere.
Grants were awarded to:
- Georgia Institute of Technology, Atlanta, Ga, $899,956
- North Carolina State University, Raleigh, N.C., $893,439
- University of California, Davis, Calif., $900,000
- University of Iowa, Iowa City, Iowa, $899,401
The health effects of exposure to ambient PM include premature death, aggravation of respiratory and cardiovascular disease, aggravated asthma, acute respiratory symptoms, chronic bronchitis, decreased lung function, and increased risk of heart attacks.
