Stovers,

I found the message below about air quality to be extremely 
interesting.   It comes from Kirk Smith's Google Group, which is "stove" 
(without the final s in our Stoves Listserv.)   The address is at the 
end if you want to subscribe to it.  (only a few messages per month, 
without discussion back and forth.)

Two trips, within and going out of India.  Note nearly 3 orders 
magnitude difference in exposure rates at different points. I suppose 
the very clean aircraft air is partly due to  good filtering, but also 
because of clean outside air at 36,000 ft/k

[Using what is turning out to be a nicely functioning portable monitor 
reading in ug/m3 of PM2.5 (The Oceans, made in Hong Kong and retailing 
for $120 in Delhi). /Sorry to those who do not usually frame PM2.5 
numbers in your head—remember the WHO level is 10 in these units, US 
standard is 12, and India’s is 40.  These are annual levels to stay 
healthy based on somewhat different criteria in each case.}/

At take-off, it slowly declined and by the time the seatbelt light went 
off it was 1 (yes 1 and probably actually near zero since the device has

Outside our flat: 280

Inside flat with two air cleaners going: 120

_Delhi to Toronton to SFO_

Wake up in morning: 420 in living room, moved air cleaners from bedroom

Web indicated nearby ambient monitor had reached over 600 during night

After two hours, it came down outside to about 260 outside and about 65 
in the flat

Gave away our air cleaners to friends in early eve and the level inside 
rose to about 200

Get into taxi at 9:30 when it was 290 outsides

Inside airport it was about 90

Went to 1 during the rise to flight altitude after takeoff and stayed 
there for 14 hours

6 in the jetway in Toronto

1-3 in various parts of the Toronto terminal.

Note, the web showed the nearest government ambient monitor to read 21

Jetway 6

Flight to SFO: 1

SFO terminal: 3

Outdoors at terminal 10
