EC number: 217-886-1 | CAS number: 1999-85-5
According to “The guidelines for the testing of chemicals” (HJ/T 153 -2004) and with reference to Procedure 201of the “Guidelines for Testing of Chemicals” of the OECD: “Daphnia sp., Acute Immobilisation Test” (2004) etc., this test was designed to determine the acute toxicity of test substance(meta-Diisopropanolbenzene) to Daphnia magna. The study comprised at least one range-finding test followed by a limit test to determine the 48-hour median effective concentration (EC50) of the test substance. In addition, the NOEC (no observed effect concentration) was also determined.
During the whole test period, the pH values of the control mediums and test mediums were between 7.12 and 7.65, and the Dissolved Oxygen (DO) values varied from 86% to 102% of the air saturation. During the test, the temperature of the test mediums were maintained in the range of 20.1oC to 20.8oC, and all daphnia in the control group were normal. With the same conditions, K2Cr2O7 was used as the negative control substance, and the resulting 24 h-EC50was0.65 mg/L. So the study met the acceptability criteria and was considered valid.
Under valid test conditions mentioned above, the 48h EC50is greater than 150 mg/L (nominal concentration). And 48h NOEC value (no observed effect concentration) is greater than 150 mg/L (nominal concentration). According to “The guidelines for the hazard evaluation of new chemical substances (HJ/T 154-2004)”, the test substance of meta-Diisopropanolbenzene belongs to low toxic chemical for Daphnia magna.
Under valid test conditions mentioned above, the 48h EC50is greater than 150 mg/L (nominal concentration). And 48h NOEC value (no observed effect concentration) is greater than 150 mg/L (nominal concentration).
