Short-term toxicity to fish

2 -Aminoethyldiethylamine is with high probability acutely not harmful to fish.

Key study: Leuciscus idus, DIN 38 412 -L15 (equivalent to OECD 203), non-GLP, no analytical verification (BASF AG, 1987, report no.: 10F0143/875047): 96 -h LC50 = 100 to 215 mg/L (nominal, CL not determined, non-neutralized test solutions); 96 -h LC50 > 464 mg/L (nominal, CL not determined, neutralized test solutions)

Supporting study: Leuciscus idus, DIN 38 412 -L15 (equivalent to OECD 203), non-GLP, no analytical verification, read-across to CAS 104 -78 -9 (BASF AG 1988, report no.: 10F0561/875051): 96 -h LC50 = 146.6 mg/L (geomentric mean, nominal, CL not determined, non-neutralized test solutions); 96 -h LC50 > 464 mg/L (nominal, CL not determined, neutralized test solutions)
