Additional information

One key study (K1) is available for this endpoint. In this study, the ability of heptanoic acid to immobilise Daphnia magna was tested in a GLP guideline study according to OECD TG 202 at concentrations of 0 ; 18 ; 32 ; 56 and 100 mg/L. The EC50(48 h)-value was estimated to be 72 mg/L.
