| Abstract | High levels of air pollution are one of the most concerning health and environmental hazards in Hanoi Metropolitan Region (HMR) covering the whole Hanoi capital city and partly area of 9 surrounding provinces. This study updated the emission inventory dataset from the previous study conducted at Asian Institute of Technology (AIT) Thailand (Phuc, 2018) for 2010 with the anthropogenic emissions of CO; SO2; NOx; NMVOC; PM10; PM2.5; BC; OC; NH3; CO2; CH4 and N2O in HMR were in Gg/year of 686; 2.2; 85; 173.6; 15.9; 14.5; 2.7; 3.1; 2.5; 11,257; 8 and 143, respectively covering key sources (on-road mobile, power generation, industry combustion, biomass open-burning and residential combustion). Accordingly, the industrial stacks emission under category of large point sources (LPS) in 2010 were separated from the emissions of other sources for which prevented from a more elaborate dispersion modeling PM2.5 and other pollutants. Detail activity of the LPS emissions in the HMR domain were collected to improve the emissions input data for WRF/CAMx (Weather Forecast Research Model/Comprehensive Air Quality Model with Extension) modeling system. The results showed that the annual emissions from LPS in the domain were 0.2 Gg NMVOC, 3.3 Gg PM2.5, 5.4 Gg PM10, 0.5 Gg CO and 0.66 Gg SO2. The simulated PM2.5 concentration in HMR for the base case (2010) showed that the level of PM2.5 emission mostly exceeded WHO guideline (10µg/m3 ); however, it is under the NAAQS of Vietnam and hotspots of industrial estate in other surrounding provinces. The gridded PM2.5 were input into the BenMAP-CE (Benefits Mapping and Analysis Program - Community Edition) to quantify the associated mortality health burden as compared to the scenarios when PM2.5 in the domain would meet the WHO guideline and Vietnam NAAQS, respectively. The total mortality health burden related to PM2.5 was around 2,399 people while 264 deaths caused by lung cancer, 540 deaths caused by respiratory diseases, 506 deaths by ischemic heart diseases and 1687 deaths by cardiovascular diseases compared to WHO guideline. The findings of this study for health effects are basically similar to Phuc (2018) which the hotspot is mostly appeared in the central of Hanoi. Future studies should continuously update the emission input data for modeling to provide the science-based information for comprehensive air quality management policies in the domain. |
