Ozone pollution still high

Air pollution by ground-level ozone continued to affect many countries across Europe during summer 2014, according to a new briefing published by the European Environment Agency (EEA). Almost all reporting countries exceeded at least once the long-term objective set by EU legislation, while the stricter alert threshold was exceeded only on four occasions.

Even though the ozone levels significantly exceeded the EU standards during summer 2014, the number of exceedances was lower than in many previous years, in line with the long-term downward trend observed over the last 25 years. Exposure to high concentrations of ground-level ozone can cause and aggravate cardiovascular and respiratory diseases and also damage vegetation such as forest trees and agricultural crops. More detailed information on ozone measurements in each country as well as background information on ozone is available in the EEA briefing.
