Description of key information

Read across data ethylenediamine en hexamethylenediamine (source OECD SIDS):
Ethylenediamine 21 days reproduction test dapnia magna, NOEC = 0,15 mg/l
Hexamethylenediamine: applying an assessment factor of 100 to the lowest experimentally derived acute LC50 or EC50 values for algal,
daphnid, and fish species, the MTC = 14.8 mg/L/100 or 0.148 mg/L
EUSES2.1 modeling 1,4 diaminobutane: regional PEC surface water (total) calculated = 0,00036 mg/l at production 8 kton/y. The calculated environmental exposure is much lower then the expected NOEC concentration.
