Irceline publishes PM2.5 stats for Belgium. Here's [1] a pretty little chart with the annual mean PM2.5 concentration. If you switch between 2020 and 2019, the difference seems pretty small. Same for PM10 and Black Carbon. If the pandemic had a big impact on air quality, that effect seems to have skipped Belgium at least. It's a shame there's no similar dashboard for viruses and allergens.

I wonder what the PM1 and under figures would look like. I recall seeing some analysis stating that the bulk of car related PM was smaller than PM1.
That's pretty much what the black carbon component indicates.
