Description of key information

TheDaphnia magna immobilization test was performed for the test chemical by following the OECD guideline 202. the test chemical was poorly soluble in water, and acetone has been used as the carrier solvent. the test was performed for the period of 48 hours. The test was conducted by taking the five different test concentrations i.e., 1.2, 2.5, 5, 10, 20, 30, and 40 mg/L, along with solvent control (K2Cr2O7).

On the basis of mobility of daphnia, the test chemical EC50 was determined 48.1 mg/L with confidence intervals of 39.3 and 58.9.

On the basis of mobility of daphnia, the test chemical EC50 was determined 48.1 mg/L with confidence intervals of 39.3 and 58.9. Based on the median effective concentration of test chemical it can be classified into aqucatic chronic 3 category.
