Researchers clear the air on power plant emissions

The 猫咪社区 team compared SOA emissions (crosses) with terpene emissions (shaded areas) to gain a better understanding of the impact of power plants on air quality,

Government regulators are not measuring the full effect of power plants on air quality, according to a team of 猫咪社区 researchers, because they fail to account for the interaction of power-plant emissions with natural emissions from a surprising source—trees.

In some cases, the impact of these so-called “secondary organic aerosols” is almost twice as strong as the pollution that is currently measured at the smokestack, calling into question the adequacy of conventional methods for measuring air quality.

The  by Prof. [chemistry and environmental studies], Prof.  [political science and environmental studies], Kristin Bott [Instructional Technology Services], Marisa Hazell ’15, and Raphaela Hsu-Flanders ’16, published in the June 2015 issue of Environmental Science & Policy, shows that the impact of trees on air pollution is much more complicated than you might think.
