The NOEC of quinic acid is >= 5000 mg/L for Daphnia magna during the test period of 48 h. Accompanying TOC-analysis resulted in mean measured concentrations of 133.6, 572.4 and 2211.0 mg/L in the lowest, middle and highest test concentrations. This corresponds to recovery rates of 97.8, 104.7 and 101.1%, indicating that the test item was stable during the test period of 48 h.
Quinic acid was tested in a static Daphnia magna, Acute
Immobilisation Test according to the OECD Guideline 202 for 48 h. Five
nominal concentrations between 312.5 and 5000 mg/L were used. Daphnids
did not show any adverse effects (including abnormal behaviour) in the
controls and test concentrations. The NOEC of quinic acid is >= 5000
Further, in the study, published by Henschel, 1997 the EC50 of the read
across substance salicylic acid for Daphnia magna was determined
in fresh water for 48 h according to OECD Guideline. The EC50 of
salicylic acid is 118 mg/l. In the publication of Sanderson 2009, the
LC50 of the read across substance shikimic acid for Daphnia magna is
given. The LC50 of shikimic acid is 116 mg/L.
