Study finds gasoline exhaust contributes more to formation of secondary organic aerosols than diesel

Green Car Congress

Contrary to expectations, exhaust from gasoline vehicles contributes more to the production of secondary organic aerosols (SOA) than exhaust from diesel vehicles, according to a new study by scientists from the Cooperative Institute for Research in Environmental Sciences (CIRES), NOAA’s Earth System Research Laboratory (ESRL) and other colleagues.

CMU study finds SOA levels in cities like LA will remain high despite cleaner cars; nonlinear relationship between SOA and NOx

Green Car Congress

The findings of a study by researchers at Carnegie Mellon University, with colleagues at UC Berkeley, suggest that changing atmospheric NO x levels over the next two decades will likely significantly reduce the effectiveness of stricter new gasoline vehicle emissions standards in reducing concentrations of secondary organic aerosol (SOA).

U Toronto studies find traffic emissions spread farther than thought; 25% of cars causing 90% of pollution

Green Car Congress

A trio of recently published studies from a team of University of Toronto engineers has found that air pollution could be spreading up to three times farther than thought, contributing to varying levels of air quality across cities. We used to think that living near a major road meant that you lived near a lot of air pollution.
