Reactions: air pollution decreased in Europe in the last two decades, but increased by ozone in southern regions
Research led by ISGlobal and the Barcelona Supercomputing Center (BSC-CNS) shows that air pollution in 35 European countries - including Spain - has decreased in terms of levels of suspended particulate matter (PM2.5 and PM10) and nitrogen dioxide (NO2). However, ozone (O3) pollution increased in southern Europe, as shown by daily data collected between 2003 and 2019 and published in the journal Nature Communications. The study also looked at the number of days on which limits for two or more pollutants were exceeded simultaneously: despite improvements, 86.3% of the European population experienced at least one day with compound pollution per year.
