目的为探讨出生前后低水平铅暴露对新生儿出生体重的影响。［方法］用原子吸收分光光度计 测查了 １５６例婴儿出生时血铅水平，并就低水平铅暴露（＜ ０． ４８μｍｏｌ几）对婴儿的出生体重的影响进行统计学分析。 结果血铅≥０．４８μｍｏｌ／Ｌ的新生儿体重明显低于血铅水平＜ ０． ４８μｍｏｌ／Ｌ者，分别相差 ２３０ｇ和 ４９３ｇ，差异有非常 显著意义（Ｐ＜０．０１）。结论当新生儿脐血铅水平≥０．４８μｍｏｌ／Ｌ时，确能对胎儿发育产生不良影响。
Objective To investigate the effect of low level lead exposure before and after birth on newborn birth weight. [Method] The blood lead levels of 156 infants were measured by atomic absorption spectrophotometer and the effects of low level lead exposure (<0.48 μmol few) on the birth weight of infants were statistically analyzed. Results The body weight of newborns with blood lead ≥0.48μmol / L was significantly lower than that of blood lead <0. 48μmol / L, respectively, a difference of 230g and 493g, the difference was significant (P <0.01). Conclusion When the neonatal umbilical cord blood lead levels ≥ 0.48μmol / L, can have a negative impact on fetal development.
