多氯联苯(PCB)和多溴联苯(PBB)都是亲脂性的,不易被代谢。在人体组织中的半减期长,在被污染的水中饲养的鱼脂肪组织中其浓度相当高。多数密执安居民体内有低浓度PCB和PBB。有报告指出,这些物质可通过胎盘。本文对313名妇女及其新生儿进行了这方面的研究。PCB和PBB用填充柱气相色谱法测定
Polychlorinated biphenyls (PCBs) and polybrominated biphenyls (PBBs) are lipophilic and are not readily metabolized. Half-lives in human tissues are long and their concentrations are relatively high in fish adipose tissue reared in contaminated water. Most Michigan residents have low concentrations of PCBs and PBBs. It has been reported that these substances can pass through the placenta. This article conducted a study of 313 women and their newborns in this area. PCB and PBB were measured by packed column gas chromatography
