Portland State study: urban cyclist uptake of air toxics can double in high-traffic areas

A Portland State University (PSU) study published in the new edition of “Environmental Science & Technology,” found Portland cyclists can inhale up to twice the concentration of air pollution on high-traffic streets than on low-traffic streets.

The concentration of volatile organic compounds (VOCs) in cyclist breath after riding on streets with high vehicle traffic was 40 to 100 percent higher than on low-traffic routes. The ambient levels of VOCs on the high- traffic streets were 100 to 200 percent higher than on streets with less traffic.
