本文对居住在上海地区271名非铅接触者采用阳极溶出伏安法测定了血铅含量.居住在市区的血铅正常值95％上限为31.2微克/100毫升,郊区的血铅正常值95％上限为19.5微克/100毫升,两者有显著差异。男女性别和年龄之间均无显著差异.调查结果表明,正常人血铅浓度的中位数与环境中铅的污染有着密切关系.
In this study, blood lead levels were determined by anodic stripping voltammetry in 271 non-lead contacts living in Shanghai.The upper limit of 95% of the normal blood lead for living in urban areas was 31.2 μg / 100 ml, and the normal blood lead level The upper limit of% is 19.5 μg / 100 ml, with a significant difference between the two. There was no significant difference between men and women in gender and age.The survey results showed that the median of blood lead levels in normal people is closely related to lead pollution in the environment.
