宣化城区大气TSP浓度特征及来源分析

Analysis of Air TSP Concentration Features and Sources in Urban Area of Xuanhua

以宣化区大气环境监测数据为基础 ,评价了宣化城区非采暖期和采暖期TSP污染的现状 ,分析了TSP污染的日变化特征。根据X荧光分析测定的TSP元素成分 ,采用因子分析法探讨了TSP污染的来源。宣化城区TSP在非采暖期以冶金行业排放为主要来源 ,采暖期则以燃煤为主要来源。最后 。

Based on air environmental monitoring data,current status of TSP pollution in urban area of Xuanhua City,Hebei Province in both non\|heating period and heating period was evaluated,and the daily variation feature of TSP concentration analyzed.Acording to element composition of TSP determined by using X\|ray fluorescence,the method of factor analysis is adopted to explore sources of TSP.Metallurgy industry is the main source of TSP in non\|heating period,while fuel coal is the main source in heating period.Finally,some viable countermeasures for TSP pollution control were proposed for the sources.
