For biological monitoring of workers exposed to polychlorinated biphenyl (PCB) compounds, a gas-chromatographic method for analysis of PCBs in serum was developed. The quantitation is performed with 15 pure isomers, and extraction and concentration factors are corrected with the aid of asymmetric PCB compounds added to each specimen. By this method, humans with no known occupational exposure to PCB compounds showed PCB levels in serum that were always less than 3 micrograms/l. Workers exposed in capacitor accidents have shown maximal concentrations close to 50 micrograms/l.
为了对接触多氯联苯（PCB）化合物的工人进行生物监测，开发了一种用于分析血清中多氯联苯的气相色谱法。使用15种纯异构体进行定量，并借助添加到每个样本中的不对称多氯联苯化合物校正提取和浓缩因子。通过这种方法，没有已知职业性接触多氯联苯化合物的人血清中的多氯联苯水平始终低于3微克/升。在电容器事故中接触多氯联苯的工人显示出的最高浓度接近50微克/升。
