  • Title: [Influence of prenatal exposure to low levels of lead on the neuro-behavioral development of neonates].
    Author: Ma Y, Ye G, Tang S.
    Journal: Zhonghua Yi Xue Za Zhi; 1997 Oct; 77(10):774-5. PubMed ID: 9772526.
    Abstract:
    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 mumol/L were markedly lower than those with less than 0.14 mumol/L, and the difference was highly significant. CONCLUSION: Blood lead levels of less than 0.48 mumol/L could still have harmful effects on the development of children.
