Blood lead (Pb-b) concentrations, hematocrit (Ht), and hemoglobin (Hb) were determined in three groups of men working in different parts of a cable-producing factory. All three parameters examined, i.e., Pb-b, Ht, and Hb, in the above groups were found to be within "normal" limits. However, within each group of men studied, there was a statistically significant negative correlation between Pb-b concentrations and Ht and Hb values. This finding indicates that any increase in Pb-b concentration, even within the "normal" values, may result in a decrease of hematocrit and hemoglobin values of the same subjects.
对一家电缆生产厂不同部门工作的三组男性进行了血铅（Pb-b）浓度、血细胞比容（Ht）和血红蛋白（Hb）的测定。上述三组中检测的所有三个参数，即Pb-b、Ht和Hb，均在“正常”范围内。然而，在每组研究对象中，Pb-b浓度与Ht和Hb值之间存在统计学上显著的负相关。这一发现表明，即使在“正常”值范围内，Pb-b浓度的任何增加都可能导致同一受试者的血细胞比容和血红蛋白值下降。
