Figure Twenty-sixth highest ozone 2010, based on daily running 8h max with percentage of valid measurements 75 % in μg/m3
The map shows the proximity of measured O3 concentrations to the target value set in the European Union's Air Quality Directive. At sites marked with dark orange and red dots, the daily maximum 8-hour mean O3 concentration exceeds the 120 μg/m3 threshold on more than 25 days per year (the policy target is set at max. 25 days of exceedance per year, averaged over 3 years).

Figure Number of days on which ozone concentrations exceeded the long-term objective for the protection of human health during summer 2014 (provisional data)
The long-term objective (LTO, i.e. the maximum daily 8-hour mean concentration of ozone should not exceed 120 μg/m3) was exceeded in almost all Member States and in 81% of all reporting stations - except Croatia, Estonia, Ireland, Romania and Serbia.

Figure Number of days on which the 2012 target value for the protection of human health was exceeded (summers of 2012, 2013 and 2014)
The 2012 target value was exceeded in 14 reporting EU Member States (Austria, Bulgaria, Croatia, Cyprus, the Czech Republic, France, Germany, Hungary, Luxembourg, Poland, Portugal, Slovakia, Slovenia and Spain) and in two of the other reporting countries with enough data in the three years period (Serbia and Switzerland).

Highlight More efforts required to reduce ozone pollution in Europe
Ground-level ozone is one of the most harmful air pollutants in Europe today. A new report by the European Environment Agency (EEA) shows that despite efforts to reduce ozone pollution, in 2010 levels continued to exceed the long-term objective established in EU legislation to protect human health. EU Member States will also face difficulties in meeting the target value, applicable as of 2010.
