[Stoves] benefits from reduced indoor air pollution.

I've changed the subject from the thread where I took Cripin's quote
from to try and shift the discussion to more technical matters

Firstly is there any reason given for men's higher exposure? Perceived
wisdom is that young children were more at risk (at a given level of
exposure) as their immune systems were naive  plus presumably their
cell divisions are more active and hence open to more chance of
disruption.

Anyway does anyone think that the recent US EPA step 2 rules for
pollutant emissions via chimneys/flues venting outside are at all
relevant as a target for stoves?

They seem to be independent of thermal power  in that they accepts
2-2.5 grams particulates per cubic meter irrespective of heat
liberated and also susceptible to dilution or have I missed something?
