[Objective] The purpose of this paper is paper was to master the spatial and temporal distribution of total antimony content in fresh vegetables in Hunan Province. [Method] Fresh vegetable samples were collected in 14 areas of Hunan Province and Xikuangshan Street. The content of antimony was detected by Hydride Generation-atomic fluorescence spectrometry. The spatial and temporal distribution of total antimony in fresh vegetables in different areas and seasons were compared. [Result] In 703 vegetable samples,the reference range( P5-P95) of total antimony content was ND-0. 25mg/kg,and the median was 0. 018 mg/kg;and the median of total antimony content in Xiangtan City and Xikuangshan Street were 0. 046 and 0. 041 mg/kg respectively,significantly higher than those in other areas. The differences among groups were statistically significant( P < 0. 05). The reference range of total antimony content in spring samples was ND-0. 24 mg/kg,and the median was 0. 023mg/kg; the reference range of total antimony in autumn samples was ND-0. 088mg/kg,and the median was0. 007 4 mg/kg. [Conclusion] The reference range of total antimony content in Hunan Province is ND-0. 25mg/kg,and the median is 0. 018 mg/kg. The content of total antimony content in Xiangtan City and Xikiangshan Street is higher. And the total antimony content in spring samples are higher than those in autumn samples.

The content of total antimony content in Xiangtan City and Xikiangshan Street is higher. And the total antimony content in spring samples are higher than those in autumn samples.
