The Department of Environmental Protection has issued an ozone air quality alert for much of Pennsylvania.
A 2013 report by the American Lung Association has found that the air in and around Philadelphia may put people’s health at risk.
This spring, runny eyes and a stuffed up nose may not be the result of seasonal allergens.
Philadelphia and its surrounding counties are under a “code orange,” meaning the air contains unhealthy levels of ozone.
Orange means unhealthy pollution levels for sensitive people. Next would be red, which is unhealthy air for all.
