Air Quality
Outdoor air quality is affected by multiple pollutants from a variety of sources. Air quality in Cincinnati is monitored daily by the Southwest Ohio Air Quality Agency for ground-level ozone, particle pollution (particulate matter), carbon monoxide, sulfur dioxide, nitrogen dioxide, and pollen and mold. The Agency also regulates industrial air emissions for Butler, Clermont, Clinton, Hamilton, and Warren counties.

-
Support and fund the development of natural corridors and tree barriers along streams and rivers, interstates and highways.
-
Strengthen air emissions regulations.
Air Quality Studies in Cincinnati: Cincy Air Watch
Cincy Air Watch is a joint effort with the Office of Environment and Sustainability (OES) and the Cincinnati Health Department (CHD) to support the 2023 Green Cincinnati Plan strategy to “increase air quality studies, education, and reduce pollution from air emissions in the city.” Through this project, PurpleAir monitors were installed in Cincinnati neighborhoods and the data is provided publicly in real-time. The initiative aims to enhance local community awareness of local air quality conditions and to investigate the relationship between air quality, asthma, tree canopy coverage, and heat island effects.
