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. Additional information Air pollution by ozone across Europe during summer 2010
