#ISESISIAQ2019 key results reported by S. Chillrud (scholar.google.com/citations?hl=e…) on Stove intervention study in Ghana.
Ambient PM2.5 exposure was around 35-50 ug/m3. Highest exposure was measured for women who did tons of cooking, showed high compliance wearing the personal exposure monitors. those who used an LPG stove arm were exposed to only 9 ug/m3 over ambient.
whereas those who cooked with the traditional 3 stone stove where exposed to 52 ug/m3 above ambient, so found an 83% reduction when using the LPG stove.
LPG stove was very popular - used a lot. Biolite (modified biomass stove) was not used as much, probably not liked so did not reduce PM exposure at all.
IMPORTANT: Biomass improved stove not effective at reducing exposure confirming need to move towards clean fuel interventions-must provide developing communities access to alternative fuel sources such as LPG in place of biomass. #ISESISIAQ2019 @EllisonCarter
