Asphalt roads are a significant source of air pollution in ...

2020-9-2  Asphalt may be a significant, yet overlooked, source of air pollution in urban areas. In a new paper published on 2 September in Science Advances, scientists reveal that common road and roofing asphalts emit hazardous pollutants, especially, on hot sunny days (1).. A considerable proportion of air pollutant in cities is believed to come from sources other than fossil-fuel guzzling vehicles.

2020-9-3  To assess the impact of such non-combustion sources, the researchers collected fresh asphalt, a material found in roads, roofs and driveways, and heated it to different temperatures. They found that when asphalt is exposed to moderate solar radiation it results in a 300% increase in seconadry organic aerosols (SOA).
