英文摘要：

Because of its merits of rapid analytical speed,high sensitivity and high accuracy,gas chromatography-mass spectrometry is used more and more widely in element speciation analysis.In this study,the interface design methods of GC-MS were briefly reviewed.Moreover,the existing forms and speciation analysis significance of arsenic,selenium,mercury and lead were introduced,and the application of GC-MS in speciation analysis of arsenic,selenium,mercury and lead were reviewed.Finally,the development tendency and limitation of this combined technology was prospected.
