Right so Neil honed in on this little counter intuitive snippet from
that abstract, kerosene can be cleaner than LPG but is this with an
optimally performing LPG stove?

Has anyone with access to the full report garnered anything else, like
why does a forced draught or insulation increase carbonyls or PAHs, I
can well understand (and Tami mentioned it in the past) that a fan can
loft ultrafine particles of ash but how could increasing turbulence
with a fan or temperature with insulation lead to higher emissions of
PAH's. I would expect more compounds containing carbonyl groups to get
oxidised to CO2 with increased temperature and mixing.
