Description of key information

3hr EC50: >100 mg/l (activated sludge respiration inhibition, OECD 209)

Key value for chemical safety assessment

Additional information

An activated sludge respiration inhibition 3hr EC50 value of >100 mg/l (loading rate) was determined in a reliable study conducted according to an appropriate test protocol, and in compliance with GLP. This indicates that the test substance was not toxic to waste water (activated sludge) bacteria at a loading rate of 100 mg/l.
