Urinary arsenic levels of 2065 nonoccupational exposed subjects in Henan were determined by spectrophotometric analysis. The results showed: (1) The difference was not significant among Zhengzhou, Luoyang, Anyang, Xinyang and Shangqiu (0.01 < P < 0.025). (2) The difference was not significant among different ages(0.01 < P < 0.025) and between sexes(P > 0.05). (3) The distribution was positive skewness. The median of urinary arsenic was 17.8 micrograms/L. The arithmetic mean was 20.7 micrograms/L. The standard deviation was 15.2 micrograms/L. The geometric mean was 17.3 micrograms/L. (4) It is suggested that the reference upper limit value of urinary arsenic for nonoccupational exposed subjects in Henan in 56 micrograms/L.
采用分光光度分析法测定了河南2065名非职业暴露人群的尿砷水平。结果显示:(1)郑州、洛阳、安阳、信阳和商丘之间差异无统计学意义(0.01<P<0.025)。(2)不同年龄组之间差异无统计学意义(0.01<P<0.025),男女之间差异无统计学意义(P>0.05)。(3)分布呈正偏态。尿砷中位数为17.8微克/升,算术均数为20.7微克/升,标准差为15.2微克/升,几何均数为17.3微克/升。(4)建议河南非职业暴露人群尿砷参考上限值为56微克/升。
