I was dismayed to learn recently that Government measures to reduce air pollution have been put on hold during the coronavirus lockdown. While it may well be that there is less pollution from traffic and manufacturing during the lockdown, around where I live at least, wood-smoke pollution seems to be increasing, with smoke coming out of chimneys from domestic wood-burning stoves more than usual and lots of people having barbecues and bonfires. Since many of us are stuck at home all day we will be breathing more of the resulting smoke than we would normally.

Given that it is known that smoke is injurious to lung health even in normal times, and that pollution-damaged lungs can increase the severity of Covid-19, it would surely be good if everyone made an effort to refrain, as far as possible, from smoke-producing activities during the lockdown?
