SoE2020: Ozone concentrations

While hourly ozone levels in Townsville, Gladstone and South West Queensland have never exceeded the National Environment Protection (Ambient Air Quality) Measure 1-hour average standard of 0.100ppm, in the past 14 years South East Queensland experienced exceedances on 2 days in 2011, and 1 day in 2015, 2018 and 2019. All exceedances are linked to extra emissions of photochemical smog-forming pollutants from major bushfires.
