       本研究基于Models-3/CMAQ空气质量模式和IER综合暴露响应模型评估了融合在线监测排放信息长三角排放清单的改善程度及超低排放政策的环境与健康效益。融合在线监测数据的排放清单更能反映实际排放特征明显改善区域空气质量模拟效果在长三角地区,若仅电力部门实施超低排放控制政策,空气环境质量改善和人体健康风险降低的效果非常有限超低排放政策扩大到水泥、钢铁和工业锅炉等非电行业减排效益明显提升,PM2.5暴露的人群死亡率下降约5.5%。因此,加强对多类排放源协同控制进一步降低空气污染和健康风险的重要途径

       祝贺张妍!

 

  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.
