Exposure to NET60

The evolution of the percentage of the population that is exposed to daily maximum 8-hour mean ozone concentrations above 120 µg/m³ shows that the last 10 years were favourable ozone years. In this period, no one has been exposed to maximum 8-hour mean ozone concentrations above 120 µg/m³ on more than 25 days. In 2016, 78% of the population was exposed to maximum 8-hour mean ozone concentrations > 120 µg/m³ on 10 or fewer days. By contrast, 1990, 1995, 2003 and 2006 were very unfavourable in terms of population exposure to high ozone concentrations. In those years, the majority of the population (above 80%) was exposed to maximum 8-hour mean concentrations above 120 µg/m³ on more than 25 days.
