The EC50 results obtained after 48 h acute test for gemifloxacin and gatifloxacin was 489.2 mg l−1 and 330.8 mg l−1 respectively. Adverse effect on reproducibility was observed on 21st day of exposure as a chronic toxicity test. The survival of Daphnia magna reduced to zero after exposure of 94.5 mg l−1 and 202.5 mg l−1 of gemifloxacin and gatifloxacin respectively.
