Abstract: 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.
