Earth Week: New research links lung cancer to air pollution in Philadelphia
Air in the Philadelphia region is ranked as the 12th most polluted in the country by the American Lung Association. Toxins in the air, mainly from traffic and industry, are known to cause lung cancer. Trevor Penning, a pharmacology professor in the Perelman School of Medicine, developed hazard indices for 421 zip codes using satellite imagery for particulate matter and volatile organic compounds. Penning traced 70,000 lung cancer cases between 1998 and 2017 to air pollution in certain zip codes in the Philadelphia region, finding that the highest polluted areas track with the I-95 Corridor.
