Maryland 8-Hour Ozone Concentrations Exceeding 2015 Health-Based Standard in ppb, Finalized Data. In 2015 EPA set the ozone standard to 70 ppb. High levels of ozone can cause health effects including increased asthma attacks and other respiratory effects. You can get more information about the health effects at http://www.epa.gov/air/ozonepollution/. This data set details which monitoring locations in Maryland exceeded the standard between 2016 and 2021 and the maximum concentrations on the dates the standard was exceeded.
