Whilst being UK centric and relating to diesel exhaust plus a bit of
blurring between NOx and particulates some explanation is given for
lumping all PM 2.5 into the measurements.

The thing is as I understand it PM2.5 from naturally aspirated biomass
stoves are bound to contain Polycyclic Aromatic Compounds and thus
likely to be in the more damaging class of particulates?
