Abstract

There are several basic principles that apply to the clinicopathologic syndrome produced by polychlorinated biphenyls (PCBs). They are as follows: The degree of halogenation and position of the halogen atoms determine the potency of PCB, PBB, CDD, CDF and CN; in a given species of animals, the clinicopathologic syndrome induced by PCB is comparable to that induced by polybrominated biphenyls (PBB), chlorinated dibenzo-p-dioxins (CDD), chlorinated dibenzofurans (CDF), and chlorinated naphthalenes (CN) when an equitoxic dose is achieved; The clinicopathologic syndrome is different in each species of animals; Different species of animals vary in their susceptibility to intoxication; intoxication is more readily effected in young animals that in adults; at lethal doses the time between exposure and death is prolonged (greater than 2 weeks).

摘要

有几条适用于多氯联苯(PCBs)所产生的临床病理综合征的基本原则。具体如下:卤化程度和卤原子的位置决定了多氯联苯、多溴联苯、二恶英、呋喃和氯化萘的毒性;在给定的动物物种中,当达到等毒性剂量时,多氯联苯诱发的临床病理综合征与多溴联苯(PBB)、二氯二苯并对二恶英(CDD)、二氯二苯并呋喃(CDF)和氯化萘(CN)诱发的临床病理综合征相当;临床病理综合征在每种动物物种中都有所不同;不同动物物种对中毒的易感性各不相同;幼龄动物比成年动物更容易发生中毒;在致死剂量下,接触与死亡之间的时间会延长(超过2周)。
