摘要
采用较为先进的中子活化检测方法(NAA),对韶关市区20～55岁的非神职业正常人群作了发砷含量的初步研究,结果均低于国内部分地区的发砷值水平,发砷含量中位数为0.121μg/g,几何平均数为0.118μg/g,同时提出了95％该人群的发砷值上限为0.320μg/g。
The hair arsenic levels of nonoccupq-tional esposed nornal subjects,aged 20~55 years,were analysed by neutron activation analysis in Shaoguan.The median and geometric mean are 0.121μg/g and 0.118μg/ g respectively.These results are lower than many other reports in China.This paper proposes the 95% upper Limit value of hair arsenic level is 0.320μg/g.
