摘要
研究血铅低于０．４８μｍｏｌ／Ｌ时新生儿的神经行为发育是否仍受到不良影响。方法调查１３１例新生儿，用新生儿２０项行为神经评分法检测新生儿神经行为发育，石墨炉原子吸收光谱测定脐带血中铅的含量。结果血铅≥０．２９μｍｏｌ／Ｌ的新生儿其神经行为发育明显落后于血铅＜０．１４μｍｏｌ／Ｌ者，两者比较差异有显著意义。结论血铅水平低于０．４８μｍｏｌ／Ｌ时，仍可对婴幼儿神经行为发育产生不良影响。
Objectives To study the effects on the neuro behavioral development of neonates exposed to low levels of lead in utero.Methods 131 neonates were selected and their umbilical blood lead level was determined by Atomic Absorption Spectrometer. The neurobehavioral cognitive performance of neonates was evaluated by Neonatal Behavioral Neurological Assessment (NBNA).Results NBNA scores in neonates with blood lead levels greater than or equal to 0.29 μmol/L were markedly lower than those with less than 0.14 μmol/L, and the difference was highly significant.Conclusion Blood lead levels of less than 0.48 μmol/L could still have harmful effects on the development of children.
