Quantification of Indoor Air Pollution & Estimating its Health Effects in Northwest Bangladesh, 2011.
Leah T. Le, et al. ETHOS Conference, Kirkland, Washington, January, 2011.
Stoves Used
- Improved stoves designed by Bangladesh Council of Science and Technology (BCST)
- Iron gate and chimney
- 3 model types: 1-pot, 2-pot, and 3-pot stance
- Thermal efficiency tested by Appropriate Rural Technology Inc. (ARTI)
- Water boiling test
Conclusions
- 59% & 23% reduction in PM2.5 & CO emission,respectively, from improved stoves after 1 year. But not significant
- Predominate chemical species: EC, OM, Chlorine, and Potassium
- As long as they continue to be exposed to such CO & PM2.5 concentrations, cooks are potentially suffering from mild symptoms every day, all year, every year.
- Fuel use patterns and cooking practices seen in this population are likely to be comparable to much of Bangladesh.
