Additional information

Reliable measured and modeled BCF data for o-tert-amylphenol and its structural analogues o-tert-butylphenol and o-sec-butylphenol are available and included in the dossier. Chemical Evaluation and Research Institute Japan (2008) provide a measured BCF value of 78 for the common carp exposed to the read across substance o-tert-butylphenol. Consequently, this value will be taken for the aquatic bioaccumulation in aquatic organisms endpoint.

Reliable modeled BCF value for o-tert-amylphenol, using the measured log Kow of 4.0 was estimated to be 121 L/kg wt for earthworm. These data indicate that there is very low potential for bioaccumulation of o-tert-amylphenol in terrestrial organisms.
