摘要
ＰＣＢ广泛存在于水体、大气、土壤等环境介质中，对藻类细胞成份、光合能力等产生影响，对鱼和水生无脊推动物的生长起抑制作用，浓度高时导致死亡，对动物的繁殖具有阻碍作用，对人体有毒害作用，可通过胎盘进入胎儿体内；已培育出一些可降解ＰＣＢ的微生物。
AbstractPCB disseminates broadly In environment media such as water,air,soil,etc,resulting in a series of ccological effects,including inhibiting growing,cell cornposition and photosynthesis ability of algae .The fresh water algae haye much more strong resistance to PCB than seawater algae.PCB will inhibit the growing of fish and aquatic invertebrate animals.It will lead them to death if the concentration is high,PCB will himder the reproduce of animals. The method of body fluid immune is highly sensitive so it will become new immune inspect method.PCB will poison the body of person.It can enter the body of embryo passing by placenta,Now,some microor-ganisms have been found,which can break PCB down.
