Harmful ozone pollution was the worst for almost a decade in large parts of Europe this summer, particularly during the long August heatwave, according to a preliminary assessment by the EEA. The unusually hot and sunny weather, combined with air pollutants emitted mainly by traffic, industry and vegetation, caused very long lasting and geographically extensive ‘episodes’ with high concentrations of harmful ground-level ozone. And this situation is likely to repeat itself in any future summers with above-average temperatures until measures taken under current legislation result in a much larger cut in emissions of the ‘precursor’ pollutants that cause ground-level ozone, towards the year 2010.
