[Stoves] CO, personal exposure, rural Kyrgyzstan

Dear Andrew

The measurements are pre-intervention. We should have the 'after' in two weeks plus‎.

The peaks are indeed ‎100 ppm and during the last day it was above 50 most of the time. The peaks are refueling episodes, de-ashing and ignitions.

If it was very cold, the long continuous highs are associated with leaks from the stove through poor joints, poorly fitting doors, cracked cast iron, and corroded mild steel. Lack of chimney draft is a major issue so that air is not pulled in, smoke is pushed out.

There is little correlation between PM and CO but that said, it is fuel-dependent. The discontinuities ‎change with the fuel.

Regards
Crispin

The image is a bit blurry but CO seems to nudge 100ppm at peak, what
do the peaks correspond to?

Is there a correlation between pm2.5 and CO?

Is this before or after intervention?
