摘要
目的研究怀孕30周孕妇和其新生儿脐带血镉的含量,分析有关影响因素。方法收集66名孕妇静脉血和其新生儿脐带血各40μl,采用原子吸收光谱仪测定血镉的含量,并分析孕妇家庭和社会环境等有关因素30个项目。结果孕妇和新生儿脐血镉的平均水平分别为(2.38±0.86)μg/L和(1.66±0.62)μg/L。血镉水平≥2μg/L的人数,孕妇为42例,新生儿为17例,各占63.64%和25.76%,二者之间正相关有统计学意义(r=0.58,P<0.01)。结论孕期被动吸烟、孕期喝牛奶、孕龄、新生儿性别对脐血镉水平有显著影响。妇幼工作者应对围生期的镉损伤给予高度重视。
Objective To examine the blood cadmium of the woman at 30 weeks of gestation and its umbilical cord blood, and analyze some relevant influential factors. Methods The venous blood of 66 pregnant women and the umbilical cord blood were collected for 40μl respectively, the blood cadmium was detected by atomic absorption spectrometry and the family-socio-economic conditions of each woman were analyzed. Results The blood cadmium levels of pregnant women and of umbilical cord were （2.38±0.86） μg/L and （1.66±0.62）μg/L, the case of the blood cadmium ≥2 μg/L were 42 and 17 respectively. Between them there was a positive correlation （r = 0. 58, P （0.01）. Conclusions Passive smoking, drinking milk during pregnancy, antepartum period and neonate sex were the factors affecting the cadmium levels of umbilical cord blood. Cadmium damage of prenatal period should be paid great attention by women and children health workers.
