Finding F-0356

“Similarly, HCHO levels drop from 1.9 μg m−3 in C1 to 0.9 μg m−3 in C4, a 52.6% decrease, further supporting the superior combustion efficiency of groundnut-rich blends.”

Structure

Source
Biomass fuel
Factor
Formaldehyde (CH₂O)
Intervention
Clean fuels
Setting
laboratory cookstove test, IN
Study design
laboratory combustion tests of fuel cakes made from cow dung and groundnut shell in four blends (C1 100 % cow dung to C4 25 % cow dung and 75 % groundnut shell) in a rural cookstove: calorific value and emissions of PM2.5, CO2 and formaldehyde (class 4)
Effect
difference
Caveat
fuel blend filed under clean-fuels; laboratory test, not household exposure
