Description of key information

The toxicity of C36-alkylenediamines to microorganisms was tested according to OECD guideline 209. The NOEC after 3 hour exposure as observed in a limit test was 999 mg a.i./L. 

Key value for chemical safety assessment

EC10 or NOEC for microorganisms:
999 mg/L

Additional information

A Respiration Inhibition Test with activated sludge according to OECD Guideline No. 209 (2010) was carried out with the test item Amines C36-alkylenedi-.Test system was activated sludge of a municipal treatment plant. The test was carried out under static conditions with the limit concentration 1000 mg/L. The respiration rates of the control, reference and test item replicates were measured after a contact time of three hours, and the inhibitory effects of the test and reference item were determined in comparison to the control respiration rates. The inhibition of respiration for the test item replicates ranged from - 1 to - 6 %. Validity criteria of the test guideline were fulfilled.

The NOEC of the test substance C36-alkylenediamimes is 1000mg/L test substance or 999 mg/L based on active ingredient content.
