Description of key information

Read across data ethylenediamine (source OECD SIDS): chronic toxicity to fish, NOEC>10 mg/l, 28 days growth of species gasterosteus aculeatus.
EUSES2 modeling 1,4 diaminobutane: regional PEC surface water (total) calculated = 0,00036 mg/l at production 8 kton/y. The calculated environmentalexposure is much lower then the expected NOEC concentration.

Key value for chemical safety assessment
