Lead concentrations in whole blood and saliva were examined in 16 females and 13 males living in Klity village, a highly contaminated area from lead mining, Thailand. The geometric mean for the lead content in the blood was 24.03 microg/dl (range 11.80-46.60 microg/dl) while the lead content in the saliva was 5.69 microg/dl (range 1.82-25.28 microg/dl). No significant differences were found between the concentrations of lead in blood and saliva in relation to the age of the subject. Males were found to have higher blood lead levels than females. The coefficient of correlation gamma between salivary and blood lead levels was -0.025. Our data suggests that saliva is not suitable material for biological monitoring with respect to lead exposure.
对居住在泰国铅矿开采高度污染地区克利蒂村的16名女性和13名男性的全血和唾液中的铅浓度进行了检测。血液中铅含量的几何平均值为24.03微克/分升（范围为11.80 - 46.60微克/分升），而唾液中的铅含量为5.69微克/分升（范围为1.82 - 25.28微克/分升）。在受试者年龄方面，血液和唾液中的铅浓度未发现显著差异。发现男性的血铅水平高于女性。唾液和血铅水平之间的相关系数γ为 -0.025。我们的数据表明，就铅暴露而言，唾液不是适合进行生物监测的材料。
