Seasonal Air Quality Patterns
Summer brings highest ozone levels, particularly affecting the northeastern part of the state. Winter can see particulate matter issues in valleys and urban areas. Lake Erie can moderate air quality in northern regions but also contribute to specific weather patterns that affect pollution dispersion.
Health Impacts
Ohio's older industrial cities have communities with elevated pollution exposure. The transition away from coal has improved air quality but legacy health impacts persist in some areas. Urban-rural disparities in air quality are notable across the state.
Recommendations for Ohio Residents
Ohio residents should monitor air quality forecasts during summer months. Those living near industrial areas should be aware of specific local sources. Support clean energy transitions that will continue to improve state air quality. Consider indoor air filtration in urban areas.
