Man-made pollutants significantly influence how tree emissions form aerosol particles

The southeastern United States is a natural laboratory for scientists studying how chemicals emitted by human activities and trees interact with each other and affect air quality and climate. A new study has found that certain emissions from cars and coal-fired power plants promote processes that transform naturally occurring emissions from trees into organic aerosols. Organic aerosols make up a substantial fraction of ambient particulate matter (PM) that can affect climate, air quality and human health.

Georgia Tech City Planning Students Lend Expertise to Neighborhood in Need

Students from Georgia Tech’s School of City and Regional Planning are offering their expertise this semester by working with Atlanta area communities to develop a long-term plan for their neighborhoods.

Professor Nancey Green Leigh and her class of graduate students are partnering with Georgia Conservancy and community leaders of Neighborhood Planning Unit (NPU) G located on the west side of Atlanta close to the intersection of Interstate 285 and Hollowell Parkway to improve the area.
