Comprehensive Impact Assessment for Control of Precusors of Ozone and Fine Particle
Absrtact |
Analysis of the concentration of water-soluble ions in fine suspended particulates from 105 to 108 years showed that the concentration of PM2.5 in Taiwan has decreased, so the concentration of major ions has also decreased. The analysis of the daily reverse trajectory of ozone events shows that the reason for the excessive O3_8hr in the western half of Taiwan is transmission within an hour, and the ozone sensitivity is controlled at the same time as the two pollutants of VOCs and NOx. However,match simulation to get priority control NOx.The combination of simulation results and combined with TEDs emissions. The plan proposes to prioritize the control of large trucks (diesel), self-use minibuses (gasoline) and four-stroke locomotives in the line source, and achieve the priority control of the line source through the emission reduction of the vehicle type, and then target the point source and the area source. List the industries that require priority control. In point sources, priority should be given to the power supply industry, non-hazardous waste treatment industry, plastic-related manufacturing, and steel-related industries. In terms of non-point source pollution, it is recommended to target ship and commercial emissions and surface coating industry. According to CMAQ, the impact of the power industry is simulated. Regarding the contribution of ozone, regardless of coal-fired and gas-fired power plants, the contribution ratio is the largest contribution ratio in the southwestern half of the coast. Discussion on the trend of changes in
