Description of key information

In 2004, the assessment of the inhibitory effect of ATG and MeaTG on the respiration of activated sewage sludge was carried out by Clarke according to OECD TG 209 and GLP requirements. Based on the results of this study, the effect of the test material on the respiration of activated sewage sludge microorganisms gave a 3-hour EC50 of 530 mg/L and greater 1000 mg/L for MeaTG. The No Observed Effect Concentration (NOEC) after 3 hours exposure was 32 mg/L for both substances.

Key value for chemical safety assessment

EC50 for microorganisms:
530 mg/L
EC10 or NOEC for microorganisms:
32 mg/L
