摘　　要：分别采集了宝鸡市3个监测点大气中总悬浮颗粒物(TSP)样品,同时收集了土壤尘、煤烟尘、建材尘、交通尘和钢铁尘5种源样品。采用X-射线荧光光谱仪分别测定受体和源样品中11种元素的质量比。应用受体模式的化学质量平衡法对宝鸡市区大气总悬浮颗粒物来源进行解析。结果显示:分析的5种源样品对TSP的贡献率分别是土壤尘41.91%、煤烟尘24.42%、建材尘20.17%、交通尘5.83%和钢铁尘3.91%。The samples of total suspended particulate （TSP） were collected at three sites in Baoji City. At the same time, the samples of 5 sources were collected, such as soil dust, coal smoke dust, building material dust; traffic dust and steel dust. Eleven elements in both source samples and receptor samples were measured by X-ray fluorescence spectrometer. The pollution sources of total suspended particles in Baoji City were analyzed by the chemical mass balance method （CMB） based on receptor model. The results show that the contribution rates of five major sources to TSP were： soil dust（41.91% ）, coal smoke dust（24.42% ）, building material dust（20.17% ）, traffic dust（5.83% ） and steel dust（3.91% ）.
