Conclusions:
LC50 of FAT 21030/C was determined to be 0.63 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 21030/C for 48 hours at following concentrations: 0.2, 2, 20 and 100 mg/L.

After 48 h of exposure, no mortality was seen at 0.2 mg/L, however 100 % mortality was observed with 2, 20, and 100 mg/L test concentrations. Based on these findings, the LC50 of FAT 21030/C was determined to be 0.63 mg/L.

Description of key information

FAT 21030 was tested for short term toxicity to fish in studies where a methodology similar to OECD Guideline 203 was employed. Groups of 8 fish were exposed to FAT 21030/A, FAT 21030/B and FAT 21030/C at 0.2, 2, 20 and 100 mg/L test concentrations in three different studies. While no mortality was observed at 0.2 mg/L, remaining concentrations were very toxic to the exposed fish. At 2 mg/L,1/8, 0/8 and 0/8 fish survived in the studies with FAT 21030/A, FAT 21030/B and FAT 21030/C, respectively. The remaining concentrations of 20 and 100 mg/L lead to 100 % mortality in all three studies. The LC50s obtained with FAT 21030/A, FAT 21030/B and FAT 21030/C were 0.63, 0.63 and 0.75 mg/L, respectively.
