59.5 mg/L

Additional information

To assess the short-term toxicity of 3 -aminopropyldimethylamine towards D. magna, a 48-h static non-GLP test was performed according to EEC-Guideline 79/831/EEC method C.2, which is equivalent to OECD 202 (Daphnia sp. Acute Immobilisation Test). The stability of the test substance in the test medium has not been analytically verified, but it is considered to be stable due to the high water solubility, the low Henry´s law constant and the low adsorption potential (log Kow and log Koc < 3) of the substance. The pH values of the test solutions were not adjusted and ranged from 7.9 to 8.6, therefore staying in the limit given by the OECD guideline 202 (pH value 6 to 9). Based on nominal concentrations, the 48-hour EC50 was estimated to be 59.5 mg/L (BASF AG, 1988, report no.: 1/0556/2/87 -0556/87).

In conclusion, 3 -aminopropyldimethylamine is acutely harmful to aquatic invertebrates.
