Lead was measured in the milk of 39 lactating women to determine if the concentration posed a toxicological hazard to nursing infants. Blood and hair of these women were also analyzed for lead to establish possible correlations with milk, and to indicate body burdens. The women were categorized as rural or urban residents so that all mean values of lead could then be correlated with their locations. The mean levels of lead in milk, blood, and hair were 3, 119 ng/ml and 2002 ng/g (ppb), respectively. Lead levels in milk were not considered high enough to pose any threat to the nursing infant. Furthermore, the levels in blood and hair were below values typically cited as average. The three biological parameters did not correlate significantly with each other or with the location of these women. Therefore, it does not appear that the women in this study have high body burdens of lead, or that the nursing infant is at any risk of lead exposure via milk.
对39名哺乳期妇女的乳汁进行了铅含量测定,以确定其中的铅浓度是否会对哺乳婴儿造成毒理学危害。还对这些妇女的血液和头发进行了铅分析,以建立与乳汁中铅含量的可能关联,并表明身体负担情况。这些妇女被分为农村或城市居民,以便所有铅的均值都能与她们的居住地点相关联。乳汁、血液和头发中的铅平均水平分别为3 ng/ml、119 ng/ml和2002 ng/g(ppb)。乳汁中的铅含量被认为不足以对哺乳婴儿构成任何威胁。此外,血液和头发中的铅含量低于通常引用的平均值。这三个生物学参数彼此之间以及与这些妇女的居住地点均无显著相关性。因此,本研究中的妇女似乎没有高铅身体负担,哺乳婴儿也没有因乳汁接触铅的任何风险。
