Pay attention at the back Desai senior

I was making the point that the sooty black PM we have coming from
burning biomass (or badly burning kerosene or bituminous coal for that
matter) have adsorbed on their surfaces the Poly Cyclic Aromatic
Hydrocarbons that are amongst the most worrying  for the  lung and
possible carcinogens.

As such they are a subset of all PM2.5 and presumably among the most
toxic outsde of industrial exposure to asbestos fibrils, thus taking
on board that all PM2.5 do not have the same toxicity.
