为了解新生儿脐带血血铅浓度及其环境影响因素，在南通市收集脐带血标本１３９份。用火焰原子吸收法测定血铅浓度，并以访谈式问卷调查的形式对相应的１３９名产妇进行了环境因素的调查，用多因素统计分析的方法，分析对脐血铅水平有影响的环境因素。结果：１３９例脐带血铅浓度呈正偏态分布，范围在０．０１２９～０．４６６９μｇ／ｍｌ，中位数为０．１４２７μｇ／ｍｌ，脐带血铅水平超过目前认为的安全界限０．１μｇ／ｍｌ的占７３．４％。研究还发现，高龄孕妇、孕妇被动吸烟、饮茶、用陶瓷杯饮水、上下班途中时间长是胎儿期铅暴露的危险因素，而孕妇多食豆制品为保护性因子。
In order to understand neonatal umbilical cord blood lead concentration and its environmental factors, cord blood samples collected in Nantong 139. The levels of blood lead were measured by flame atomic absorption spectrometry. The environmental factors were investigated in the form of interviews with 139 maternal women. The multivariate statistical analysis was used to analyze the environmental factors influencing lead levels in umbilical cord blood . Results: The blood lead levels of 139 cases were positively skewed and ranged from 0.0129 to 0.4669μg / ml with a median of 0.1427μg / ml. Cord blood lead levels exceeded the currently accepted safety margin of 0.1μg / ml Accounted for 73.4%. The study also found that pregnant women, pregnant women, passive smoking, drinking tea, drinking water with a ceramic cup, work long hours on the way to the risk of fetal lead exposure, while pregnant women eat soy products as a protective factor.
