| 摘 要： | 本研究表明:汉沽污水库进水口污水对鱼类毒性很大,它对白鲢、鲤鱼和鲫鱼24小时半数致死浓度分别为3％、30％和58％(V/V)。汉沾污水库对化工废水有一定自净能力,净化后的水质是有益于鲫鱼生存、发育和繁殖的。污水库中的鲫鱼对DDT积累不明显;对666虽有积累但不超过食用标准(2ppm);对汞的积累量较高,100天内鲫鱼肌肉汞含量超过食用标准(0.3ppm)26倍。鲫鱼对汞、DDT、666均有排除能力,其排除速率的快慢顺序为:666>DDT>Hg。

| Abstract: | This study indicates that the wastewater import of Hangu stabilization pond is very harmful to fish. A value of 24 Lc50 of the influent for siver carp (Hypophthalrnichys molitrix)carp(Cyprinus carpio)and crucian carp(Carassiws aur-atus)was measured as 3 %,30% and 58% in V/V respectively.Hangu stabilization pond has ability to self-purification for chemical industry wastewater. After stabilization, the water quality of pond was good for survival, growth and breeding of crucian carp.It isn't obvious for the c... |
