Description of key information

One long term toxicity test with daphnia has been performed. The NOEC for adult mortality is 320 µg/L based on the test substance (90.4% diamine and 9.6% primary alkyl amine). 100% adult mortality was observed at the next higher concentration of 1000  µg/L. The EC50 for adult mortality is 566  µg/L. No effects on reproduction were observed upto 320 µg/L. The effects are expressed as nominal values because the tests were performed with river water as they are intended to be used in an evaluation of the environmental risks based on the Bulk approach.

Key value for chemical safety assessment

EC10, LC10 or NOEC for freshwater invertebrates:
320 µg/L
