Additional information

The determination of the inhibition of mobility (acute toxicity) of the freshwater Daphnia magna exposed to the test item N-[2-(piperazin-1-yl)ethyl]C18-insaturated-alkylamide for a duration of 48 hours was performed following the method C2 described in Directive 92/69/EEC of the European Commission and in the guideline 202 (part I) of the OECD.

The 48-hour EC50 of N-[2-(piperazin-1-yl)ethyl]C18-insaturated-alkylamide to D. magna under static conditions was 0.44 mg a.s./L (median lethal concentration).
