Description of key information

A limit test with a nominal concentration of 12 mg/L was performed. This concentration was chosen according to the OECD Series on Testing and Assessment No. 126 “Threshold approach for acute fish toxicity”. It was the lowest EC50 determined in the algal growth inhibition test.
No fish died or showed any abnormal behaviour during the 96 hours exposure period. Therefore the LC50 is > 12 mg/L.
The analytical determination of decamethylenediamine resulted in 11.8 mg/L at the start and 11.5 mg/L at the end of the experiment. Therefore the concentration analysed was always > 80% of the nominal concentration.

Key value for chemical safety assessment

LC50 for freshwater fish:
12 mg/L
