Progress Summary:
The Firepower Sweep Test, developed as part of this work, better replicates the range and variability of cookstove emissions measured in field settings relative to use of the traditional Water Boil Test (WBT). The WBT under-predicts both the magnitude and variability of emissions in the field.
Our atmospheric aging experiments suggest that the radiative properties of cookstove emissions can be reliably modeled using Mie theory for OA:BC > 4, which is a safe assumption for atmospherically relevant conditions.
Our study developed a first estimate of 270,000 adult mortalities (yearly, across the globe) due to chronic exposure to ambient fine particulate matter (PM2.5) from uncontrolled combustion of domestic waste. This likely is a conservative estimate due to the resolution of the model.
A major finding of this work is that uncertainties in the concentration-response function dominate the sensitivity of estimates of mortality from exposure to PM2.5 from cookstove emissions. Estimated mortality due to exposure to cookstove emissions (both at the indoor and outdoor levels) is strongly sensitive to uncertainties in the concentration-response function and less sensitive to the concentration of exposure.
Future Activities:
We will submit journal publications on (1) results of the 2014 Front Range Cookstove Study, (2) optical properties of cookstove aerosols, (3) results of the field emissions trials, and (4) sensitivity analysis on the inputs to modeling the global burden of disease from exposure to household air pollution.
