Description of key information

Brooke et al. (1984 and 1984b) were selected as key studies. Conditions of both of these studies were the same: Pimephales promelas were exposed to vanillin  under flow-through conditions. The 96H-LC50 was 57 mg/L in the first study and 123 mg/L in the second, based on measured concentrations. No discussion about the differing results was provided by the authors. A geometric mean of these 96H-LC50 was calculated at 83,7 mg/L.

Additional information

Another 96H-LC50 value on the same fish was in the same range : 112 to 121 mg/L. A 24H-LC50 on Oryzias latipes has been reported at 117 mg/L. Both of these publications have been selected as supporting studies.

Vanillin is considered to be harmful to fish.
