Air pollution in Europe is shortening lifespans by an average of eight months and by as much as two years in the most polluted cities and regions, according to a report from the European Environment Agency (EEA). While the European Union has cut emissions of many harmful pollutants over the last decade, the report finds that nearly a third of urban dwellers are still exposed to harmful levels of airborne particulate matter, tiny pollutants small enough to penetrate the respiratory system and cause serious health ailments. About 21 percent of city dwellers are exposed to particulate matter above EU health standards. And 17 percent were exposed to higher levels of ozone, which can cause respiratory problems. “In many countries, air pollutant concentrations are still above the legal and recommended limits that are set to protect the health of European citizens,” said Jacqueline McGlade, executive director of the EEA. According to the report, humans living in industrial regions of Eastern Europe face the highest exposure to harmful pollutants.
