Study on the Inventory of Air Pollutants in Ports of Beijing-Tianjin-Hebei Region

According to the 2014 national transportation statistics compilation, the throughput and port machinery classification data of the port-based cargo types in the Beijing-Tianjin-Hebei region in 2014 were obtained. Based on the relevant research results, the calculation methods and related parameters of port heavy trucks, other port machinery, unorganized emissions of particulate matter, and unorganized emissions of VOCs were determined. To calculate the list of atmospheric pollutants in the Beijing-Tianjin-Hebei regional port in 2014, The emissions of SO2, NOx, PM10, PM2.5, VOCs and CO from Tianjin Port, Qinhuangdao Port, Huanghua Port and Tangshan Port were 260.6t, 3784.5t, 2524.1t, 2376.4t, 986.6t and 3068.9t respectively. Combined with the overall planning and layout plan of the Beijing-Tianjin-Hebei Port, the GIS technology was used to grid the inventory data to obtain a spatialized list with a resolution of 3km×3km. To further study the differences in emissions of different pollutants in different ports and the distribution of air pollutant emissions in the port to laid a scientific data foundation. (paper)
