作者报道了一位从1982年5月4日至5月20日期间每天8小时接触铅尘的受孕女工,虽然在本例未见有铅中毒的症状,但在其他接触者中则可见到。作者对母亲及其胎儿做了铅含量的监测,监测的时间从终止接触时开始并连续进行六个月直至含量正常。因铅从血液中消除的半减期大约要20天,估计在终止接触时母体铅负荷为1200 ppb,但测定结果表明胎儿组织样品中铅含量为0.4(脑)和0.07(肝)μg铅/g干重,胎儿铅主要贮存在骨骼、血液 The authors reported that a pregnant female worker exposed to lead dust 8 hours a day for the period from May 4 to May 20, 1982, had no symptoms of lead poisoning in this case but was seen in other contacts. The authors monitored mothers and their fetuses for lead levels, starting from the termination of contact and continuing for six months until normal levels were achieved. Approximately 20 days after the half-dead due to elimination of lead from the blood, it is estimated that the lead load at the termination of contact is 1200 ppb. However, the measurement results indicate that the lead content in fetal tissue samples is 0.4 (brain) and 0.07 (liver) μg lead / g dry weight, fetal lead stored mainly in the bones, blood
