Description of key information

The 72h EC50 was > 1000 mg/l

Key value for chemical safety assessment

EC50 for freshwater algae:
1 000 mg/L

Additional information

The results from a fully completed GLP study for toxicity to aquatic algae according to OECD201 revealed that the 72h EC50 was > 1000 mg test item/L. A NOEC could not be derived because the growth inhibition showed an invers dose-response relationship. The test concentration of 120 - 580 mg/l showed a growth inhibition of 14 - 17 %. At 1000 mg/L 6 % growth inhibition could be observed.
