"Decoding the Hazards of Philadelphia's Worst Air Quality Day in a Decade"

Philadelphia is experiencing a serious air quality event due to smoke from wildfires in Canada, with health officials warning of "code red" conditions. The air particles affecting people are known as PM 2.5 particles, which can cause coughing, discomfort, and adverse health effects for those with heart or lung disease. To protect health, people should avoid going outside, close windows, and use HEPA air purifiers. Masks such as N95 or KN95 can help reduce particulate matter. Parents of kids with asthma should be alert to symptoms and consider treating their children early.
