摘要：Through the probe into a certain petrochemical enterprise and its ambient atmospheric particle samples, the temporal and spatial distribution characteristics of the particles of different sizes were discussed. Besides, the concentration relationship among several kinds of particles was also analyzed. Combined with the Pearson correlation analysis and factor analysis of atmospheric particles, the petrochemical enterprise was considered as an important source. The concentration distribution of particles demonstrated prominent differences in period (heating period and non-heating period) and location (distance from the petrochemical enterprise) as well as the meteorological conditions (dominant wind direction). The Pearson correlation coefficients among particles and fine particle proportion around the petrochemical enterprise were both high, which indicated that the source of the particles might be the petrochemical enterprise. Through the Principal component analysis and factor analysis of atmospheric particulate matter around the petrochemical enterprise, the conclusion was made that these pollutants mainly came from wastewater treatment plant, aromatic hydrocarbon equipment and the fugitive emission sources in the petrochemical enterprise.
