Yale study finds asphalt a significant source of air pollution, especially on hot, sunny days

Green Car Congress

A new study now finds that asphalt is a significant source of air pollutants in urban areas, especially on hot and sunny days. Yale researchers found that common road and roofing asphalts produced complex mixtures of organic compounds, including hazardous pollutants, in a range of typical temperature and solar conditions.
