Basis for effect:
mortality (fish)
Details on results:
8/8 fish survived at 24 and 48h at 2 mg/L nominal concentration.
0/8 fish survived at 24 and 48h at 20 and 100 mg/L nominal concentration.
Validity criteria fulfilled:
yes
Conclusions:
The TL50 of FAT 20013/A in this fish acute toxicity test was determined to be 6.5 mg/L.
Executive summary:

The acute fish toxicity test was performed using a methodology equivalent or similar to OECD Guideline 203. Fish were exposed to FAT 20013/A for 48 hours at concentrations of 2.0, 20.0, 100.0 mg/L. 8/8 fish survived at 24 and 48h at 2 mg/L nominal concentration and 0/8 fish survived at 24 and 48h at 20 and 100 mg/L nominal concentration. Based on the findings of the study, the TL50 of FAT 20013/A in this fish acute toxicity test was determined to be 6.5 mg/L.
