Air pollution has started to fall in many UK cities in response to the lockdown measures introduced as a result of the coronavirus crisis. The trend mirrors that seen across continental Europe as people have spent less time in vehicles, offices and factories and more time at home.
Data collected by the National Centre for Atmospheric ScieStudence shows marked reductions in nitrogen dioxide (NO2) and in particulate matter (PM2.5). And the falls look set to continue.
Professor Ally Lewis, director of science at the NCAS said:-
“If you look at traffic volumes, they’re still going down. And so we probably haven’t reached the bottom yet. ” few days ago, we were talking about journeys by car going down by about a third, and now it’s nearly a 50-60% reduction. So, it’s possible if transport keeps declining, the signal we detect could get even larger,” he told the media.
