Résumé
2.8 billion people burn solid fuels for cooking (Bonjour et al., 2013) and the resulting air pollution is the third leading risk factor for the global burden of disease, contributing to 4 million premature deaths per year (Lim et al., 2012). There are also impacts on global and regional climate systems, and ecological health. This dissertation investigates aspects of these issues as part of REACCTING (Research on Emissions, Air quality, Climate, and Cooking Technologies in Northern Ghana), a 200-home cookstove intervention study in the Kassena-Nankana (K-N) Districts of Northern Ghana that took place from 2013-2016. It contributes quantitative results from the REACCTING study, and novel exposure estimation techniques to improve intervention assessment, in five chapters. First, traditional and intervention stove use results are presented from both electronic stove usage monitors and surveys. Stove use patterns are explained, and improvements to stoves and measurement techniques are proposed. Second, origins and exposure of PM2.5 are assessed. Personal, kitchen area microenvironment, and ambient organic PM2.5 data were analyzed using positive matrix factorization, to better understand source types and relative importance at the different scales. Third, personal carbon monoxide exposure results are presented for intervention participants. Fourth, methods and results are presented for a proximity assessment system used to enrich personal exposure measurement data. Fifth, a laboratory assessment is presented for a widely used electrochemical carbon monoxide (CO) exposure monitor to better understand its strengths and limitations as relevant to this stud
