New Study Shows how Air Pollution Varies Block by Block

September 7, 2021 —

The amount of air pollution in a community depends greatly on its proximity to emission sources, such as automobiles, factories, and power plants. Now, a group of researchers — led by Joshua Apte, UC Berkeley assistant professor in the Department of Civil and Environmental Engineering and in the School of Public Health — has shown that levels of air pollution vary not only by region, such as between urban and rural areas but by city block. Their results, published this week in the Proceedings of the National Academy of Sciences (PNAS), expanded on the authors’ previous research by detailing the racial and ethnic disparities in air pollution, which showed that areas with high levels of air pollution tend to be populated by people of color.
