EPA Air Pollutant Monitoring - Nitrogen Dioxide (NO2)

Daily summary of air quality at specified locations in King County (Nitrogen Dioxide). Air quality monitors measure concentrations of NO2 throughout the country. EPA, state, tribal and local agencies use that data to ensure that NO2 in the air is at levels that protect public health and the environment. Nationally, average NO2 concentrations have decreased substantially over the years. The charts below show national and regional trends in NO2 concentrations.
