This study assesses the sources, magnitudes, and chemical compositions of household air pollution (HAP) and personal exposure in traditional Tibetan households. We measured 24-hour personal exposures to fine particles (PM2.5) and kitchen area black carbon (BC) concentrations, using MicroPEMs and microAeths, respectively. Particulate polycyclic aromatic hydrocarbon (PAH) and chemical element concentrations were quantified via post analysis of a subset of MicroPEM sample filters. Household surveys regarding participant demographics, cookstove usage, household fuel, cooking behaviors, and lifestyles were also collected. The results reaffirm that burning firewood and yak dung, mainly for cooking, leads to high PM2.5 and BC exposures.
About the speaker
Dr. Saikawa conducts research on the environment and has worked on diverse project that cover 1) atmospheric chemistry (modeling aerosoles and tropospheric ozone); 2) environmental health (assessing the adverse health impacts of air pollution); 3) biogeochemistry (modeling global spoil nitrous oxide emissions); 4) climate science (estimating emissions of non-CO2 greenhouse gases), and 5) environmental policymaking processes).
