Description of key information

Additional information

Short-term toxicity data are available for three trophic levels (fish, Daphnia and algae) for N-methyl-N-(C18-(unsaturated)alkanoyl)glycine (EC 701-177-3). The short-term toxicity to fish was determined in two studies according to internationally accepted guidelines (OECD 203 and EU Method C.1.). It could be concluded that no effects for fish were expected up to the water solubility of the substance. The short-term toxicity to aquatic invertebrates was assessed in two studies according to OECD 202 or EU method C.2. The lowest reported effect concentration is an EC50 (48 h) of 0.43 mg/L (measured). The toxicity to aquatic algae was tested in two studies according to OECD 201 resulting in an ErC50 (72 h) > 4.4 mg/L (measured) and a NOErC (72 h) of 0.91 mg/L (measured).

Two studies determined the toxicity to microorganisms according to OECD 209. The EC50 (3 h) was > 100 mg/L and the NOEC (3h) was 10 mg/L.
