为了评价胎儿期接触重金属的情况,作者于1975～1976年对比利时的503名孕妇(包括474名欧洲人,29名生活在布鲁塞尔的亚非人)进行了观察。测定每100ml全血中三种重金属的浓度,并比较了其在母血与脐带血中的分布情况。分娩时母体取静脉血,新生儿收集脐带血液。欧洲孕妇年龄为16～43岁,平均26岁;亚非人18～40岁,平均26岁。结果表明:母血与新生儿血重金属含量的相关系数铅为r=+0.808(P<0.001),汞为r=+0.624(P<0.001),镉为r=+0.38(P<0.001)。曾有人报导胎儿血汞水平略高
To assess fetal exposure to heavy metals, the authors observed 503 pregnant women in Belgium from 1975 to 1976, including 474 Europeans and 29 Asian and African living in Brussels. The concentrations of three heavy metals in 100 ml of whole blood were measured and their distributions in maternal blood and umbilical cord blood were compared. Maternal venous blood taken during birth, neonatal cord blood collection. European pregnant women aged 16 to 43 years old, average 26 years old; Asian and African 18 to 40 years old, average 26 years old. The results showed that the correlation coefficients of serum heavy metals in maternal blood and neonates were r = +0.808 (P <0.001), r = +0.624 (P <0.001) and r = +0.38 (P <0.001) Some people have reported fetal blood mercury levels slightly higher
