Nine lead-workers, with an exposure time of 26 years, are investigated 10 years, after they had retired. There are no differences in the blood-count, hemoglobin, blood-lead level, urin-delta-aminolevulinic-acid, urincoproporphyrin and delta-aminolevulinic-acid-dehydratase-activity in their blood, upon comparison with a control group without lead-exposure. The mean urinary excretion of lead (0.119 mumol/g Kreatinin = 24 microgram/g Kr.) was 8 times higher than of reached by the controls (0.014 mumol/g Kr. = 2.7 microgram/g Kr.). The injection of CaNa2-EDTA increased the lead excretion to 0.197 mumol/g Kr. = 40.8 microgram/g Kr., in the control group 0.123 mumol/g Kr. - 25.7 microgram/g Kr. (62%). Therefore these two investigations are recommended for detection of previous lead exposure.
对9名铅作业工人进行了调查，他们的接触时间为26年，退休10年后接受调查。与无铅接触的对照组相比，他们血液中的血细胞计数、血红蛋白、血铅水平、尿δ-氨基乙酰丙酸、尿粪卟啉和δ-氨基乙酰丙酸脱水酶活性均无差异。铅的平均尿排泄量（0.119微摩尔/克肌酐=24微克/克肌酐）比对照组（0.014微摩尔/克肌酐=2.7微克/克肌酐）高8倍。注射CaNa2-EDTA后，铅排泄量增加到0.197微摩尔/克肌酐=40.8微克/克肌酐，对照组为0.123微摩尔/克肌酐-25.7微克/克肌酐（62%）。因此，建议进行这两项检查以检测既往铅接触情况。
