摘　　要：目的了解我国南方某多氯联苯(PCBs)高暴露地区的产妇及其婴儿体内PCBs的蓄积水平。方法采集在当地某医院中符合条件的50对母婴对的母乳和脐带血,用GC-MS法进行PCBs含量的测定。结果母乳中13种PCBs总浓度的最大值为237 ng/g类脂,几何均数为138 ng/g类脂。脐带血中13种PCBs总浓度的最大值为102 ng/g类脂,几何均数为56.9 ng/g类脂。Objective To comprehend the accumulate levels of PCBs both in parturients and infants in a high exposure area of South China. Method Respectively collecting 50 samples of mother＇s milk and cord blood from 50 pairs of mothers-infants and determining the levels of 13 kinds of PCBs in those samples by GC-MS method. Result The maximum concentration of those 13 PCBs in mother＇s milk was 237 ng/g lipoid, the geometric mean was 138 ng/g lipoid; while the maximum and geometric mean concentrations of the 13 PCBs in cord blood were 102 ng/g lipoid and 56.9 ng/g lipoid respectively. Conclusion The study showed that both of mothers and infants in this area had a high level accumulation of PCBs.
