Epidemiology studies have proven causation between air pollution and cardiovascular disease. I am majored in public health and I was wondering whether it would be possible to access the benefits of this project in terms of public health. For example, one cohort study has quantified that the long-term hazard ratio (e.g. 10-year risk) of having cardiovascular events is 1.24 for every 10 microgram increase in PM2.5. In this project, improved charcoal stoves reduce indoor PM2.5 concentration by more than 300 microgram. I did some preliminary calculation: corresponding hazard ratio is about 16.49. That means, given 10 years, people living with traditional charcoal stoves are 16.49 times more likely to have cardiovascular events than people living with improved charcoal stoves! That could be a huge contribution to local public health.
However, this is just a preliminary estimation. Judging from standard public health approach or epidemiology method, aforementioned estimation is not accurate. If you are interested, you can contact me and I can find epidemiological study on indoor air pollution and make better estimation.
