I have already shown how that calculation is made: a cigarette exposes the smoker to 40-45 mg of PM2.5. The actual exposure for an adult living 24/7 in 160 micrograms/m^3 (bad days in Delhi) is 1/28th of a cigarette‎ per day.

Crispin would you reprise that explanation and source again for me please.

Some while back I  posted a link to a graph of particulate pollution
in UK and how ithe source from agriculture declined sharply when open
field straw burning ceased. What intrigued me was how a pollution
event that lasted only a few days affected the figures for a whole
year. It also made me wonder if  a heavy exposure for a few days was
better or worse than a continuous average exposure to the same amount?
