摘要

[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.
