The hair arsenic of the teachers of middle school was determined by neutyron activation analysis.The concentration of hair arsenic is 0.067?g/g(median)and 0.245?g/g(95% percentile);Beijing,it is 0.031?g/g(median)and 0.123?g/g(95% percentile);Shaoguan,it is 0.117?g/g(medi-an)and 0.299?g/g(95% percentile).The correlativity was showed between the hair arsenic levels and the sex,age,smoking and dietary structure(as the intakes of fish,egg,meat,vegetables).The normal reference value should be included both the lowest and highest hair arsenic levels in our country because the difference of hair arsenic level at different area had been proved.
