Seasonal Air Quality Patterns
Summer brings higher ozone levels across the state. Winter can see elevated particulate matter in valleys due to temperature inversions. Pennsylvania's location means it receives transported pollution from upwind states, particularly affecting the eastern part of the state. Spring and fall generally have the best air quality.
Health Impacts
Communities near industrial facilities, particularly in the Pittsburgh and Philadelphia areas, face elevated health risks. Valley communities can experience worse air quality during inversions. Pennsylvania's aging population is particularly vulnerable to air pollution effects.
Recommendations for Pennsylvania Residents
Pennsylvania residents should be aware of regional transport patterns that can quickly change air quality. Valley residents should monitor inversions during winter. Consider air filtration systems for homes near industrial areas. Support ongoing efforts to transition to cleaner energy sources.
