Description of key information

No inhibitory effects of the test item on microorganisms were measured in a respiration inhibition test with sludge: (IC50/EC50 (0.5 h) > 100 mg/mL). 

Key value for chemical safety assessment

Additional information

In a respiration inhibition test (Notox BV 1993c) activated sludge was inoculated with the test item resulting in concentrations of 3.2, 10.0, 32.1, 50.2, and 100.4 mg/L. The incubation period was 0.5 hours. A negative control and a positive control was included in the study. Under the conditions of this study an IC50 (0.5 hours) of >100.4 mg/L was estimated for the test item. The positive control 3,5-Dichlorophenol induced the appropriate response. In conclusion, the test item was not toxic to waste-water bacteria. This study was performed according to OECD 209 and GLP.
