2016 State of the Air in Arkansas
The ADEQ Office of Air Quality has prepared a 2016 retrospective report describing the state of air quality in Arkansas during the past decade. The report includes trends in observed air quality data for common outdoor pollutants—ozone, particulate matter, carbon monoxide, nitrogen dioxide, sulfur dioxide and lead—and their precursors. Additionally, the report includes general information about each pollutant, including its primary sources, physical characteristics, and health effects. The report also contains information about trends in emissions of pollutants in Arkansas, their effect on ambient air concentrations of pollutants, and the effects of various state and federal air quality programs on emissions and ambient pollutant concentrations over time.
Available data indicates that ambient concentrations of most pollutants have decreased during the time period evaluated in the report and that all monitoring locations in Arkansas are currently exhibiting design values well below national ambient air quality health-based standards for all pollutants.
