基于连续在线监测的长三角地区超低排放控制政策的环境和健康效益研究论文被ACP接收(Our work on the Air quality and health benefits from ultra-low emission control policy indicated by continuous emission monitoring: A case study in the Yangtze River Delta region, China was accepted by Atmos Chem Phys)

  The Models-3/CMAQ (Community Multi-scale Air Quality) system and the Integrated Exposure Response (IER) model were applied to evaluate the improved emission estimates with online monitoring data and the environmental and health benefits of ultra-low emission control policy for the Yangtze River Delta (YRD) region. Incorporation of online monitoring data in the emission inventory could better reflect the actual emissions of specific sources and clearly improve the regional air quality simulation performance. Very limited benefits on regional air quality and human health were found when the ultra-low emission control policy was conducted only in the power sector in YRD. If the policy could substantially be expanded to non-power industries like cement, iron & steel, and industrial boilers, the benefits were significantly larger, with the attributable deaths due to PM2.5 exposure reduced by 5.5%. Therefore, coordinated control of multiple sources is effective for further reducing air pollution and health risk. 

  Congratulations to Yan Zhang!

  The spatial distributions of the relative changes (%) in the simulated monthly SO2, NO2, O3 and PM2.5 concentrations in October between Cases 2 and Case 3, Case 4 in the YRD region. Note Case 2 was set as the base case for policy comparisons, and only the coal-fired power sector meet the ultra-low emission limits and the policy was strictly implemented for the industrial sector as well in Case 3 and 4, respectively.
