作者在全国统一质控标准指导下，测定了３３０名接铅工人和１００名未接铅者的血铅、尿铅、叶啉代谢指标和其他相应的生物学指标，采用现代统计学方法和ＳＡＳ软件包编制程序，以曲线拟合和判别分析为手段，制订出血铅和尿铅的标准值：本地正常上限值１．４３和０．２５ｔＬｍｏｌ／Ｌ，可接受上限值１．９３和０．３５μｍｏｌ／Ｌ，中毒诊断值３．０２和０．５６μｍｏｌ／Ｌ。同时研究了空气铅浓度与生物学指标间，血铅与其他指标间的相关性，评价了其特异性、敏感性、准确性、漏诊率和误诊率。为修订国家标准提供参考数据。
Under the guidance of the unified national quality control standards, the authors measured the blood lead, urinary lead and leaf morphine metabolism index and other corresponding biological indicators of 330 lead workers and 100 non-lead workers. By using modern statistical methods and SAS Software package compilation program to curve fitting and discriminant analysis as a means to develop the standard values of lead and lead in hemorrhage: the local upper limit of normal 1.43 and 0.25tLmol / L, the acceptable upper limit of 1.93 and 0.35μmol / L, the diagnostic value of poisoning 3.02 and 0.56μmol / L. At the same time, the relationship between lead concentration in air and biological indexes, blood lead and other indexes was studied, and its specificity, sensitivity, accuracy, missed diagnosis rate and misdiagnosis rate were evaluated. Provide reference data for revising national standards.
