摘要
研究了稀有鲫（Ｇｏｂｉｏｃｙｐｒｉｓｒａｒｕｓ）作为亚慢性毒性试验材料的可能性，测定了铬、铜、锌、镉和五氯酚对稀有鲫的７ｄ亚慢性毒性，它们对稀有鲫的无可观测效应浓度（ＮＯＥＣ）分别是２５００、１０、２００、２０和８０μｇ／Ｌ。最低可观察效应浓度（ＬＯＥＣ）则分别为５０００、２０、４００、４０和１６０μｇ／Ｌ。试验结果表明，稀有鲫是一种较好的亚慢性毒性试验材料。
This paper deals with the evaluation of Godiocypris rarus as a test organism for sub-chronic toxicity test.The 7-day subehronic toxicity of chromium,copper,zinc,cadmiumand pentachlorophenol(PCP) to Gobiocypris raurs were determined. The no observed effectconcentration(NOEC )of Cr￣(6+),Cu￣(2+),Zn￣(2+),Cd￣(2+) and PCP were 2500,10,200,20,80μg/L and lowest observed effect concentration(LOEC)were 5000,20,400,40,160 μg/L,respectively. The results indicate that Gobiocypris rarus is a suitable organism for 7-daysubchronic toxicity test.
