Impact of Improved Cookstoves on the Level of Household Exposure to CO and PM<sub>2.5</sub> in Sub-Saharan Cities: The Case of the City of Ouagadougou

Air pollution is one of the major global threats to human health. In Burkina Faso, more than 80% population uses solid fuels as main source cooking energy. This paper reports a comparative study on exposure household carbon monoxide (CO) and particulate matter (PM2.5) emitted by improved cookstoves (ICS) or traditional (TCS). A cross-sectional was conducted in city Ouagadougou for 4 months during rainy season (July October) households with an outdoor kitchen. The investigation involved 92 where air pollutants, such PM2.5 CO were measured Indoor Pollution Meters (IAP meter). These measurements focused concentration levels pollutants cooking. results this show high all type stoves.
