Los Angeles air pollution declining, losing its sting
The cleanup of California’s tailpipe emissions over the last few decades has not only reduced ozone pollution in the Los Angeles area. It has also altered the pollution chemistry in the atmosphere, making the eye-stinging “organic nitrate” component of air pollution plummet, according to a new study led by a scientist from NOAA’s Cooperative Institute for Research in Environmental Sciences (CIRES) at the University of Colorado Boulder. Read More ...
