- Executive summary:
A short term toxicity to fish with FAT 20044/A was carried out in trout fishes. 8 fishes were used per concentration (100, 200 & 1000 mg/l) were used in this study. There were no mortalities found at any concentration used. Based on the study results, the TL0, TL50 and TL100 of FAT 20044/A in trout fishes was >1000 mg/l.
