Additional information

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

Reliable modeled BCF value for o-tert-butylphenol, using the measured log Kow of 3.3 was estimated to be 24.8 L/kg wt for earthworm. These data indicate that there is very low potential for bioaccumulation of o-tert-butylphenol in terrestrial organisms.
