Executive summary:

The acute fish toxicity test was performed according to a methodology similar to OECD Guideline 203 (CIBA method A-11). Zebrafish: (Danio rerio) were used in the experiment setup. Fish were tested at these different following concentrations: 100 and 1000.0 mg/L

In conclusion the results obtained were.

LC0 = 100 mg/L

LC50 = >1000 mg/L

LC100 = >1000 mg/L.

Description of key information

LC50 = >1000 mg/L

Key value for chemical safety assessment

LC50 for freshwater fish:
1 000 mg/L

Additional information

Two acute fish toxicity test were performed according to a methodology similar to OECD Guideline 203 (CIBA method A-11). Zebra fishes were used in the experiment setup. Fish were tested at these different following concentrations: 100 and 1000.0 mg/L. In conclusion LC50 = >1000 mg/L was noted.
