*: The abiotic O2 depletion was tested at test item concentration of 10000 mg/L. Because there was no abiotic O2 depletion found in this study, also lower concentrations of test item will not lead to O2 depletion (derived values).
N,N-Bis-(hydroxyethyl)-m-toluidin was tested in an activated sludge respiration inhibition test. The EC50 value for respiration inhibition was determined to be 2170 mg/L, the EC10 was 817 mg/L.
A method which corresponds closely to OECD 209 (1984) was used. A clear dose-response curve was found for the test item. The activated sludge showed good performance in the reference test and thus was acceptable for use. The test was performed under GLP and subject to a Quality Assurance check. Based on these reasons, the reliability of the study is evaluated as Klimisch Score 1, comparable to guideline study.
