Given the local effects of co-pollutant emissions, the trading of carbon dioxide emissions between facilities to meet global objectives may improve or worsen local air quality and public health. To gear carbon trading toward maximum environmental co-benefits, a quantitative model based on facility-level carbon dioxide emissions, air pollution dispersion and concentration-response functions is proposed and applied to the Beijing-Tianjin-Hebei region to quantify potential changes of local public health caused by carbon dioxide transactions. The results show that the polluters with the highest Population Health Damage Intensity (PHDI) are medium-sized facilities, because larger facilities either employ more effective pollutant control technologies or are located farther away from densely populated areas. Using this modeling framework, key facilities, sectors and regions can be identified for maximizing the environmental co-benefits from introduction of carbon market and avoiding undesirable environmental damage. © 2016 Elsevier Ltd.

Since there haven't been any research on the explicit analysis of the air pollution of thermal power plants in Beijing-Tianjin-Hebei region, we conducted this research to complement the great need, which was based on the power plants' emission datum consisted of CEMS, EIA, as well as follow-up inspection. With these datum we built the bottom-up emission inventory of all thermal power plants in Beijing-Tianjin-Hebei region. Making use of the WRF output data, we simulated the meso-scale meteorological field by CALMET. Then we simulated the air pollution effect of SO2, NOx, primary PM10, sulfates, nitrates under different scenarios. The simulation result showed that: In 2011, the most affected subarea of the air pollution of thermal power plants was the Southwest part of the region, the highest annual average pollutants emission records was held by Shijiazhuang. After the emission reduction action has been taken, the total amount of SO2, NOx, PM10 emitted from the thermal power plants has respectively reduced 33%, 71%, 68% of those in 2011. Another gratifying result was that the annual average concentration of SO2, NOx, primary PM10, sulfate, nitrate caused by the power plants has reduced to respectively 46.34%, 78.43%, 76.34%, 39.49%, 73.87%, significantly lower than those before the emission reduction action has been taken. ©, 2015, Chinese Society for Environmental Sciences.

Since it is difficult to measure BAP unorganized emissions directly from coke ovens, a large uncertainty exists in related studies. So with the observation data and production capacity of a coke plant in Shanghai from 1999 to 2003, we used an inverse model based on AERMOD (AMS/EPA REGULATORY MODEL) to estimate the BAP emission factor. The results show that annual concentration of three monitoring stations near this plant are 0.033, 0.0024, 0.0031 μg/m3, all exceeded the standard. The unorganized emission factor from this study was 14.71 mg/tcoke, The area where BAP concentration exceeded the standard was 125km2 surrounding the coke plant and the atmospheric environment protection zone should be set to 6300 m. © 2016, Editorial Board of China Environmental Science.

Aiming at the situation of the unclear air pollutants emission of the steel industry in the Beijing-Tianjin-Heibei Region, and lacking of research on steel industry emission inventory, an emission inventory which is routing-based, from bottom to top and high temporal and spatial resolution of steel industry in the Beijing-Tianjin-Hebei Region was developed based on the data of the steel industry research, on-line monitoring and investigation of pollution sources, considering the concrete information of process equipment, environmental protection measures, productivity of the steel industry. In the research, the air pollution emissions of steel industry in the Beijing-Tianjin-Hebei Region in 2012 were calculated: SO2 was 47.16 kt, NOx was 37.22 kt, PM10 was 34.15 kt. Sintering and blast furnace units are the main air pollution emission sources. Air pollution emissions of steel enterprises in Beijing-Tianjin-Hebei region are unbalanced and mainly concentrated in Tangshan, Handan of Heibei province. Emission load and number of steel enterprise of Tangshan and Handan exceeded over 50% of the all region. ©, 2015, Chinese Society for Environmental Sciences. All right reserved. Source
