非职业人群全血中锑暴露水平的研究

目的研究非职业人群血锑暴露水平,为防控重金属锑污染及健康危害提供基础数据。方法随机选择427例非职业人群为调查对象,采集全血标本,经微波消解,采用氢化物发生-原子荧光光谱法测定全血中总锑水平,并采用统计学方法计算其特征参数。结果非职业人群血锑水平检出率为93.4%,其平均数为19.60μg/L,中位数为18.70μg/L,P5~P95范围为ND~45.00μg/L。其性别间比较,差异无统计学意义(P0.05),但各年龄组间比较,血锑水平呈上升趋势,差异有统计学意义(P0.05)。结论湘潭地区非职业人群的血锑暴露水平略高于国内其他地区,可能与饮食习惯和环境重金属污染有关。

The investigation on exposure level of antimony in blood of non-occupational exposed subjects

Objective To investigate exposure level in non‐occupational workers and to provide basic date for prevention and control of antimony pollution .Methods A total of 427 non‐occupational exposed subjects were selected .The whole blood from all the subjects were collected .After microwave digestion ,the antimony extracted from the blood ,which was detected by Hydride Gen‐eration‐atomic fluorescence spectrometry .Statistical method was used for the characteristic parameters analysis .Results The detec‐tive rate of antimony in non‐occupational workers was 93 .4% ,and the mean level was 19 .60 μg/L ,the medium level was 18 .70 μg/L ,The interquartile range was ND to 45 .00 μg/L(P5 - P95) .The difference of the antimony level between the gender had no sta‐tistical significance(P> 0 .05) .Along with the age ,the level of antimony also increased .And the differences of antimony between the different age groups had statistical significances(P < 0 .05) .Conclusion The exposure level of antimony in non‐occupational population in Hunan province is slightly higher than other districts in China ,which is possibly related to the diet habit and polluted environment .
