Causative agents were considered to be cocontaminants of PCBs such as polychlorinated dibenzofurans that are secondarily formed during heating of PCBs congeners in commercial PCB mixtures and require a second look at PCB toxicity.
成因制剂被认为是多氯联苯的污染物, 比如聚氯乙烯二苯呋喃, 而后者是商业多氯联苯混合物中多氯联苯的同系物在加热的过程中二次形成的, 并要求我们再审视一下多氯联苯的毒性.
cocontaminants of PCBs是（多氯联苯）是一种化学制剂。
