摘　　要：采用电感耦合等离子体质谱法测定空气滤尘中22种金属元素含量,并分别用富集因子法及主成分分析法对对其统计分析。结果表明Mo、Ba、W等十四个金属元素为轻微富集,Hg、Tl、Bi等五个为重富集重金属元素,Ti为极重富集重金属元素。并由主成分分析知载荷值较高的金属元素分布与人们生活中液化天然气、家用电器、实验仪器的使用以及室内装修密切相关。由此本研究揭示了室内空气滤尘重金属污染来源,为室内空气重金属污染评价方法提供了参考。Inductively coupled plasma mass spectrometry was used to determine the content of 22 metal elements in air filter dust,and the concentration factor method and principal component analysis method were used to analyze the content statistically.The results showed that 14 metal elements such as Mo,Ba and W were slightly enriched,5 heavy metal elements such as Hg,Tl and Bi were heavily enriched,and Ti was extremely heavily enriched.The principal component analysis showed that the distribution of metal elements with high load value was closely related to the use of liquefied natural gas,household appliances,experimental instruments and interior decoration.Therefore,this study revealed the source of heavy metal pollution in indoor air filter dust,and provided a reference for the evaluation method of indoor air heavy metal pollution.
