Description of key information

Depending on local conditions and existing concentrations, disturbances in the biodegradation process of activated sludge are possible

Key value for chemical safety assessment

EC50 for microorganisms:
40 mg/L

Additional information

Tridecylamine, branched and linear (CAS 86089-17-0) is a mixture of C13 isomers (branched and linear; 99.8 -100%).

The assessment of the toxicity of Tridecylamine, branched and linear (CAS 86089 -17 -0) to aquatic microorganisms is based on the experimental data from a non-GLP short-term respiration inhibition test performed by BASF AG (1992; report no.: 92/1297/08/3) following OECD TG 209. Activated domestic sludge was used as inoculum. The 30-min EC50 was stated with ca. 40 mg/l (BASF AG, 1992, Rep. no. 407). In accordance to this in another study using non-adapted industrial sludge an EC50 of 46 mg/L was determined (nominal concentrations; BASF AG, 1983). The study was comparable to OECD TG 209.

Based on the experimental data, it can be concluded that depending on local conditions and existing concentrations, disturbances in the biodegradation process of activated sludge are possible.
