Additional information

PNEC aquatic for this assessment entity is based on the lowest LC/EC50 value for Methyl Anthranilate, which is the experimental fish 96h LC50 value of 9.1 mg/L (see aquatic toxicity endpoint summary for details). The terrestrial and soil PNECs have been derived from PNECaquatic using the equilibrium partitioning method. PNEC STP is based on information content from a ready biodegradation test for Methyl Anthranilate. Absence of microbial toxicity can be inferred from biodegradation studies, e.g. if a compound degrades well in a ready biodegradability test, or does not inhibit degradation of a positive control at a certain concentration, this concentration can be used as a NOEC value. Methyl Anthranilate was found to be readily biodegradable and had no inhibitory effect at a test concentration of 100 mg/L.
