目的掌握湘潭地区的非职业人群血汞含量,为防控重金属汞的污染及健康危害提供依据。方法采用多阶段整群随机抽样法,抽取372名非职业人群的全血样本,经微波消解,以原子荧光光谱法测定全血中汞含量,并与其他地区的文献资料进行比对。结果非职业人群血汞含量中位数(P50)、5%位数(P5)、95%位数(P95)分别为2.31、0.01、6.79μg/L,其性别差异无统计学意义(P>0.05);但各年龄组血汞含量有下降趋势,差异有统计学意义(P<0.05)。结论该地区非职业人群的全血中汞含量水平较高,原因与实验室间差异、饮食习惯和环境重金属污染有关。
Objective To understand the content of blood mercury in non-occupational population in Xiangtan area and provide the basis for prevention and control of heavy metal mercury pollution and health hazards. Methods A multistage cluster random sampling method was used to collect whole blood samples of 372 non-occupational groups. Microwave digestion was used to determine the content of mercury in whole blood by atomic fluorescence spectrometry and compared with other regions. Results The median (P50), 5% (P5), 95% (P95) of blood mercury levels in non-occupational groups were 2.31,0.01,6.79μg / L, respectively. There was no significant difference in gender (P> 0.05). However, the blood mercury levels in all age groups showed a decreasing trend with a significant difference (P <0.05). Conclusion The levels of mercury in whole blood of non-occupational population in this area are higher, due to the differences between laboratories, dietary habits and environmental heavy metal pollution.
