Key value for chemical safety assessment

EC10, LC10 or NOEC for freshwater invertebrates:
0.07 mg/L

Additional information

Test was conducted with Amides, C18-unsatd., N-[3-(dimethylamine)propyl] according to approved guidelines with GLP accreditation with deviations reported and justified. A certificate of analysis was present and chemical analysis in keeping with the bulk approach was conducted with a validated analytical method. Validity criteria and guideline recommendations for a valid test were met with the exception of chemical analysis at the end of the test which is not required as part of the bulk approach.

The exposure of the test organisms to the test chemical was in keeping with the bulk approach and use of nominal concentrations for endpoint calculations is justified. The data generated in this study can be considered an accurate representation of the chronic toxic effects of the test substance to Daphnia magna in the concentration range tested. Based on the observed results the NOEC for this substance based on reproduction is 0.07 mg/L.

The adult mortality endpoint was not considered reliable due to physical effects being the most likely cause of the effects.
