我国现行的铅中毒实验室诊断指标有尿铅(Pb-U)、δ-氨基乙酰丙酸(δ-ALA)、粪卟啉、点彩红细胞(或碱性粒细胞)等。近年来国内对红细胞游离原卟啉(FEP)已有研究。认为EFP与空气铅、血铅、Pb-U的相关性比δ-ALA和粪卟啉好,且操作方法简易、迅速,是一项较为理想的生物学监测指标。本文选择某蓄电池厂一组高浓度铅接触者进行FEP测定,探讨EFP在
China’s current lead poisoning laboratory diagnostic indicators are lead (Pb-U), δ-aminolevulinic acid (δ-ALA), coproporphyrin, erythrocytes (or alkaline erythrocytes) and so on. In recent years, the domestic research on erythrocyte free protoporphyrin (FEP) has been studied. It is considered that the correlation between EFP and air lead, blood lead and Pb-U is better than that of δ-ALA and coproporphyrin, and the operation method is simple and rapid, which is an ideal biological monitoring index. This selection of a battery factory a group of high-concentration lead contact FEP determination of EFP
