Blood lead levels during pregnancy and in neonates immediately after birth have been evaluated, showing higher values in mothers compared to neonates (5.81 +/- 3.05 vs 4.87 +/- 3.60 micrograms/100 ml) and a positive correlation between maternal and neonatal levels (r = 0.82). On the basis of the results derived from the population examined, it has been observed that 6% of newborns have blood lead levels higher than 10 micrograms/100 ml a value recently identified by the Centers for Disease Control (CDC, Atlanta, USA) as a limit for toxicity in children. Moreover, neonatal Pb levels were higher than those found in infants from 6 to 12 months (4.87 +/- 3.60 vs 2.24 +/- 0.54 micrograms/100 ml). During the first week of life there is a steady decrease of blood lead levels, together with increasing renal lead excretion. This study was carried out at the "Dipartimento di Biomedicina dell'Età Evolutiva" University of Bari, southern Italy.
研究评估了孕期及新生儿出生后即刻的血铅水平，结果显示母亲的血铅水平高于新生儿（分别为5.81±3.05微克/100毫升和4.87±3.60微克/100毫升），且母亲与新生儿的血铅水平呈正相关（r = 0.82）。根据所检测人群的结果发现，6%的新生儿血铅水平高于10微克/100毫升，这一数值最近被美国亚特兰大疾病控制中心（CDC）确定为儿童中毒的限值。此外，新生儿的血铅水平高于6至12个月婴儿的血铅水平（分别为4.87±3.60微克/100毫升和2.24±0.54微克/100毫升）。在出生后的第一周内，血铅水平持续下降，同时肾脏铅排泄增加。本研究在意大利南部巴里大学的“进化生物学系”开展。
