Household air pollution (HAP) is the eighth leading risk factor for global disease burden, contributing to 2.9 million yearly premature deaths. Nearly 80% of the sub-Saharan population and about 90 million households in Nigeria use biomass as their primary fuel for cooking and energy needs, which can adversely impact their health. Exposure to air pollution has been linked to adverse pregnancy outcomes like stillbirth, preeclampsia, preterm birth, low birth weight, reduced fetal head circumference, miscarriage, and intra-uterine fetal growth retardation (IUGR).

While there have been substantial efforts to quantify the health burden of exposure to PM2.5 from solid fuel use (SFU), the sensitivity of mortality estimates to uncertainties in input parameters has not been quantified. Moreover, previous studies separate mortality from household and ambient air pollution. In this study, we develop a new estimate of mortality attributable to SFU due to the joint exposure from household and ambient PM2.5 pollution and perform a variance‐based sensitivity analysis on mortality attributable to SFU.

Residential solid biomass cookstoves are important sources of aerosol emissions in India. Cookstove emissions rates are largely based on laboratory experiments conducted using the standard water-boiling test, but real-world emissions are often higher owing to different stove designs, fuels, and cooking methods. Constraining mass emissions factors (EFs) for prevalent cookstoves is important because they serve as inputs to bottom-up emissions inventories used to evaluate health and climate impacts.
