Description of key information

The EC10 and EC50 of the substance to activated sludge (domestic sewage treatment plant) is higher than 1000 mg/L (nominal), which was the highest concentration in the test.

Key value for chemical safety assessment

EC10 or NOEC for microorganisms:
1 000 mg/L

Additional information

A study was condcuted according to EU test guidance 88/302/EEC part C and OECD guideline 209 in compliance with GLP.

No inhibition compared to blanks were observed at any concentration tested. The EC10 and EC50 of the substance to activated sludge (domestic sewage treatment plant) is higher than 1000 mg/L (nominal), which was the highest concentration in the test.

EC50 > 1000 mg/L. The substance is not considered to inhibit the respiration of sewage sludge micro-organisms.
