Asphalt adds to air pollution

[Still Waters]

Asphalt is a near-ubiquitous substance—it's found in roads, on roofs and in driveways—but its chemical emissions rarely figure into urban air quality management plans.

A new study finds that asphalt is a significant source of air pollutants in urban areas, especially on hot and sunny days.

Yale researchers observed that common road and roofing asphalts produced complex mixtures of organic compounds, including hazardous pollutants, in a range of typical temperature and solar conditions. The results of their work, from the lab of Drew Gentner, associate professor of chemical & environmental engineering, appear Sept. 2 in the journal Science Advances.

Interesting,

I just read jeans and other clothing with plastic fibers are polluting water.

We humans are really a mess.

Unintended consequences.  We do things without understanding all the impacts.
