Philly area off the ‘worst 25’ list for ozone pollution, but still gets failing grade - PlanPhilly

Results are in from the American Lung Association’s annual look at air pollution in American metro areas. There’s good and bad news for the Philadelphia region.

The area finally made it off the list of the 25 worst metro areas for ozone smog, but levels of particulate pollution are less promising.

“We have mixed results,” said Kevin Stewart, director of environmental health at the American Lung Association of the Mid-Atlantic.

The ALA’s 2022 State of the Air report looked at two types of air pollution: ozone and fine particulates. Both can come from cars, power plants, and other industrial sources — and both take a toll on people’s bodies. The report compared data from 2018-2020 to multi-year averages dating back to the 1990s.
