Additional information

None of the studies available in literature has been quoted as reliable, because of lack of data or uncertainty about the exposure.

Nevertheless, for a weight of evidence approach, these values have been retained indicating that terrestrial toxicity is not of concern for vanillin:

NOEC-42d (mortality) = ca. 10000 mg/kg dw soil on Eisenia foetida,

EC50 - 3d (seedling emergence) = 647 mg/l on Lactuca sativa

NOEC - 3d >(various growth parameters) = 304 mg/l on Echinocloa crusgalli

Furthermore, terrestrial compartment is not expected to be a compartment of concern since vanillin is expected to mainly distribute in water (98,6%) and poorly in soil (1,3%) according to McKay level I model distribution. If present in soils, vanillin (and its degradation compound, vanillic acid) have been demonstrated to be biodegraded, thus limiting the exposition through soil compartment.
