摘要
研究了三氯异氰尿酸(TCCA)和盐酸环丙沙星(CPFX)对小球藻、大型溞和稀有鮈鲫的急性毒性。毒性试验结果表明,TCCA和CPFX对小球藻的96hEC50分别为0.31mg·L-1和20.61mg·L-1、对大型溞48hLC50分别为0.19mg·L-1和135.15mg·L-1,TCCA对稀有鮈鲫96hLC50为1.76为mg·L-1,CPFX对稀有鮈鲫不产生急性毒性。对于TCCA,大型溞最敏感,小球藻次之,稀有鮈鲫最不敏感;对于CPFX,小球藻最敏感,大型溞次之,稀有鮈鲫最不敏感。
The acute toxicity of two sorts of pharmaceuticals, Trichloroisocyanuric acid and Ciprofloxacin hydrochloride to Chlorella vulgarrs, Daphnia magna and rare minnow （Gobiocypris rarus） were studied in this article. The result showed that 96hEC50 of TCCA and CPFX to Chlorella vulgarrs were 0.31mg·L^-1 and 20.61 mg·L^-1, 0.19mg·L^-1 and 135.15mg·L^-1 for 48hLC50 of TCCA and CPFX to Daphnia magna and 1.76 mg·L^-1 for 96h LC50 of TCCA to rare minnow, respectively. No acute toxicity of CPFX was found on rare minnow. For the toxicity test of TCCA, Daphnia magna was most sensitive, rare minnow was the least; for CPFX, Chlorella vulgarrs was the most sensitive, and rare minnow was the least.
