Executive summary:

FAT 41001/F was assessed for toxicity to Daphnia (aquatic invertebrates) in an immobilization test. This test was conducted in accordance with OECD test guideline 202. The test concentration used was 0, 0.01, 0.1, 1, 10, 100 mg/L. Based on the findings of this study, the EC50 in Daphnia magna after 48 h : >100 mg/L

Description of key information

The test item had no acute toxicity effects on Daphnia magna with an 48-hour EC50 >100 mg/L.
