摘要
采用回归分析和假设检验结合的方法,分采暖期和非采暖期对吉林省4个典型城市环境空气中总悬浮颗粒物和各类污染源中的无机组分进行了研究。结果表明:受体与污染源具有同源性。在采暖期,吉林市、白城市、通化市和四平市大气污染的主要来源是道路尘和土壤风沙尘,而建筑尘和煤灰对空气质量的影响较小;在非采暖期,4个城市的主要污染源分别是道路尘、土壤风沙尘和扬尘,而煤灰和建筑尘对4个城市空气质量的污染较小。研究结果有利于制定相应的大气颗粒物污染防治规划,以便提高污染防治的针对性、科学性和有效性,为大气污染防治规划提供科学依据。
The relationship between the inorganic components in TSP and their pollution sources in four typical cities in Jilin Province during heating and non-heating seasons are further studied by statisti- cal analysis. The results show that,during heating season, the main sources of air pollution in the city of Jilin, Baicheng, Tonghua and Siping are road dust,soil and sand blown by wind, while coal-fired dust and construction dust take a minor effect on the air pollution. During non-heating season, the main sources of air pollution in the four cities are road dust, soil and sand blown by wind, soil and sand blown by wind and particle mass, yet coal-fired dust and construction dust still have inconspicuous impact on the quality of local air in these cities. The improvement measures of treating TSP can be put forward by analyzing and comparing the current situation of pollution in these four cities statistically. The results of analysis provide the treatment of pollution validly and scientifically.
