Ambient air pollutant concentrations in Shijiazhuang
Dec. 18, 2013
Rapid increase in air pollutant ambient concentration in China made the Swiss Agency for Development and Cooperation (SDC) to launch a Sino-Swiss Cooperation in order to facilitate the know-how exchange regarding climate and clean air legislation. On behalf of SDC, INFRAS in collaboration with Schwank Earthparnter AG and Meteotest is supporting this partnership with expertise in air pollutant concentration modelling. In this regard, emission inventories have been developed for the chinese city Shijiazhuang. Furthermore, SO2, NO2, PM10 and PM2.5 ambient concentrations have been modelled, by means of the Swiss modelling tool PolluMap. As NO2 ambient concentration levels are comparable with european cities, SO2 and PM ambient concentrations are remarkably higher than in Europe (SO2: 50-100μg/m3, PM10: 100-150 μg/m3). Furthermore, sensitivity analysis have been conducted in order to highlight the impact of possible future measures (retrofitting of coal fired power plants, particle filters installed in diesel-engine motor vehicles).
