I thought this was well-known? I live in Montréal and there are pretty serious regulations on wood burning stoves [1-2]. I grew up in a wood heated house and I sure love sitting by the stove, but that was in the country with extremely low housing density. I'm not super convinced about indoor air pollution, with the right stove? French links, Google translate should get the gist [1] http://www1.ville.montreal.qc.ca/banque311/content/po%C3%AAle-et-foyer-au-bois-r%C3%A8glement-sur-les-appareils-et-les-foyers-%C3%A0-combustible-solide http://www1.ville.montreal.qc.ca/banque311/content/po%C3%AAl...

You still need to open them to fuel them, and people do that fairly frequently, which floods the space with particulates. > The results showed the burners were usually lit for about four hours at a time, and during this period the level of harmful particles in homes was three times higher than when stoves were not being used. https://www.theguardian.com/environment/2020/dec/18/wood-burners-triple-harmful-indoor-air-pollution-study-finds https://www.theguardian.com/environment/2020/dec/18/wood-bur...

  Presumably when the stove is not in use the amount of harful particles is very low. So a three times increase of a very small number is also very small.

    The paper says that short-term peaks are linked to health issues (from page 2): > epidemiologists are increasingly recognising that exposure to high intensities of PM over much shorter periods of time—hours rather than days—is linked to a range of health issues .Indeed, Lin et al. found a significant association between hourly peakPM2.5andmortality rates across six Chinese cities. Similarly, a systematic review of 196 articles found a positive relationship between short term PM exposure and cardiovascular, respiratory, and cerebrovascular mortality https://www.mdpi.com/2073-4433/11/12/1326# https://www.mdpi.com/2073-4433/11/12/1326#
