Description: Approximately three billion people use traditional, inefficient and poorly ventilated indoor cookstove systems to meet basic energy needs, resulting in household air pollution responsible for 4.3% of the global burden of disease. Hundreds of millions of dollars are being spent on improved stove design and dissemination, yet the health benefits from specific stove technologies are unknown. In this study, the health-relevant emissions profiles for a variety of stove and fuel combinations is being characterized, and the association between markers of cardiorespiratory health and exposure to emissions from a broad range of stove technologies will be explored, informing future directions for stove programs while providing needed insight into the question, “How clean is clean enough?” This study is one of the first controlled human exposure studies ever conducted on developing world biomass cookstoves.
