Potential Sources of Air Pollutant in Panjin

Abstract

The Hybrid Single Particle Lagrangian Integrated Trajectory (HYSPLIT), potential source contribution function (PSCF) were used to identify the transport pathways and identify potential sources of air pollution in Panjin. Three haze events were occurred in the campaign: period 1 (Nov. 2-3), period 2 (Nov. 6-14) and period 3 (Nov. 29-30) during November, 2015. The back-trajectories and PSCF analysis of three haze episodes show different air transport paths, however, Inner Mongolia and Liaoning province mostly affects the air quality of Panjin. Thus, it is necessary to enlarge degree of pollution prevention and treatment in Inner Mongolia and Gansu province to improve air quality at Panjin.
