Abstract

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.
