摘要
In order to determine the toxicity of three camptothecin formulations on Chlorella vulgaris,10-day tests were employed and data were determined every day.The results showed that 0.2% camptothecin EC had the highest toxicity to C.vulgaris in the 10d with EC50 values between 0.0368 mg.L-1 and 0.2547 mg.L-1,with the lowest value on the 3rd day.The toxicity of 0.5% camptothecin Na + SL was low,with their EC50 value between 0.6659 mg.L-1 and 2.3104 mg.L-1.The toxicity of 0.5% camptothecin K + SL increased gradually from the 2nd to the 8th days,with the lowest EC50 value of 0.4684 mg.L-1 on the 6th day.EC50 increased rapidly from 0.8024 mg.L-1 to 5.8423 mg.L-1on the 9th day.The results also showed that 0.5% camptothecin K + and Na + SL had the lowest toxicity,while the 0.2% camptothecin EC had the highest toxicity.
