Fathead minnows (Pimephales promelas) were exposed for 96hours under flow-through conditions to 5 mean measured concentrations of Hexylcinnamaldehyde in a solvent ranging from 0.12 to 2.3 mg/L. No effects were observed up to the aqueous solubility limit of the substance.
Fathead minnows (Pimephales promelas) were exposed for 96hours under
flow-through conditions to 5 mean measured concentrations of
Hexylcinnamaldehyde in a solvent ranging from 0.12 to 2.3 mg/L.
The 96hour LC50 value was 1.7 mg/L, with 95% confidence limits of 0.93
and 2.3 mg/L.
The no-mortality concentration and the NOEC were both 0.93 mg/L.
No effects were observed up to the aqueous solubility limit of the
substance. Any mortality or effects observed were therefore due to
physical effects due to the solvent artificially maintaining the test
substance in an emulsion that was stable under the conditions ofthe
study (flow-through conditions) but not possible to maintain under
