59.5 mg/L

Additional information

The acute toxicity of 3-aminopropyldimethylamine to aquatic invertebrates (Daphnia magna) was investigated in a 48-hour static test according to the EEC-Guideline 79/831/EEC method C.2 (BASF 1988). The stability of the target item in the test medium has not been analytically verified, but is considered to be stable due to the high water solubility (WS = 1E+06 mg/L), the moderate vapour pressure (VP = 5.9 hPa, at 20 °C) and the low Henry´s law constant (HLC, uncharged: 6.71E-04 Pa*m3/mol) of the substance. Based on nominal concentrations, the 48-hour EC50 was estimated to be 59.5 mg/L.
