Abstract
Regional and global air pollution contributes to poor air quality and adversely affects human health. However, chemical transport models still lack schemes in representing appropriate emissions to better simulate atmospheric chemistry and air quality, such as snowpack. In addition, the linkage between global sector-based anthropogenic emissions and human health effects associated with long-term exposure to ambient air pollutants, such as BTEX (Benzene, Toluene, Ethylbenzene, Xylene), PM2.5 (particles with an aerodynamic diameter ≤ 2.5 μm) and ozone (O3), are not well documented. Our work firstly implemented a scheme of source parameterization of snowpack-induced nitrogen oxides emissions in GEOS-Chem, which ultimately improved the tropospheric O3 simulating performance of the model by 1.57% and explained the discrepancies of tropospheric O3 distribution in polar regions. Our work focuses on the GEOS-Chem and CAM6-Chem simulated pollution impacts on BTEX, PM2.5 and O3 air quality and human health in terms of adverse birth outcomes like preterm births and premature deaths due to non-communicable diseases (NCDs) like stroke, chronic obstructive pulmonary disease (COPD), lung cancer, ischemic heart disease (IHD), and lower respiratory infections (LRIs). Our country-level analysis found that, global annual average BTEX exposure was up to 30 μg/m3 in 2015 that causes 2.01 million preterm births each year with large impacts in India, China, Pakistan, Indonesia, Bangladesh, United States and so on. Lastly, we investigated the long-term impacts of solid biofuel burning on PM2.5 and O3 air quality, as well as non-communicable diseases (NCDs) during 2000-2019. We found that solid biofuel emission supplied up to 23.6 μg/m3 PM2.5 and 13.7 ppbv O3 in 2010 and caused 1.11-1.43 million premature deaths due to NCDs annually during 2000-2019. Large air quality and human health impacts of solid biofuel burning were observed in China, India and Rest of Asia due to their large dependencies on solid biofuel for cooking and heating. This dissertation entails original works those are critically important to understand the air quality and human health impacts of natural and anthropogenic emissions.
