LC50 for freshwater fish:
748 mg/L

Additional information

The fish-acute toxicity study was conducted to Cyprinus carpio, according to the OECD Guideline 203 (1984). Fish were exposedfor 96 h in a static system to a nominal concentration range from 56 to 1000 mg/l and a control.

Analytical analysis carried out during the range finding study revealed the stability of test substance during 96 h.Moreover, the actual concentration was more than > 95 % the nominal concentration in all samples taken during the test period.

Based on these data the LC50 after 96 hours of exposure was calculated to be 748 mg/l, without mortality at 560 mg/l and 100 % mortality at 1000 mg/l.
