Description of key information

A study was performed to assess the effect of the test material on the respiration of activated sewage sludge. The method followed that described in the OECD TG 209 and conducted at the GLP-facility 9reliability of the study 1, according to the scoring system of Klimisch et al., 1997). The effect of the test material on the respiration of activated sewage sludge gave a 3 Hour EC50 of greater than 1000 mg/l. The No Observed Effect Concentration (NOEC) after 3 hours exposure was 1000 mg/l.

Key value for chemical safety assessment

EC50 or LC50 for microorganisms:
1 000 mg/L
EC10, LC10 or NOEC for microorganisms:
1 000 mg/L

Additional information

Only one study is available for this endpoint and this will be submitted as a key study for triisopropylsilyl acrylate. The effect of the test material on the respiration of activated sewage sludge gave a 3 Hour EC50 of greater than 1000 mg/l. The No Observed Effect Concentration (NOEC) after 3 hours exposure was 1000 mg/l.
