Description of key information

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.

Key value for chemical safety assessment

BCF (terrestrial species):
24.8 L/kg ww

Additional information

Reliable measured bioconcentration information for terrestrial organisms is not available for o-tert-butylphenol. However, modeled data are presented below.

The European Union System for the Evaluation of Substances (EUSES) model was used to estimate bioconcentration for o-tert-butylphenol. Using the measured log Kow of 3.3, a BCF for earthworm was estimated at 24.8 l/kg.wt.

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.
