Description of key information

The assessment of the inhibitory effect of MeaTG on the respiration of activated sewage sludge has been assessed through a test in accordance with OECD TG 209 and GLP requirements.
Nominal concentrations of 3.2, 10, 32, 100, 320, and 1000 mg ai/L were tested.
The effect of the test material on the respiration of activated sewage sludge micro-organisms gave a 3-Hour EC50 of greater than
1000 mg ai/l. The No Observed Effect Concentration (NOEC) after 3 hours exposure was 32 mg ai/l.
EC50 -30min was greater than 1000 mg/L.

Key value for chemical safety assessment

EC50 for microorganisms:
1 000 mg/L
EC10 or NOEC for microorganisms:
32 mg/L
