Description of key information

A BCF of 2.9 is estimated for 2-[2-(2-hydroxyethoxy)ethoxy]ethyl 2-hydroxyethyl phthalate , the representative of this UVCB-substance, using the EPI Suite program, v. 4.0 (Currenta, 2010).

Key value for chemical safety assessment

BCF (aquatic species):
2.9 L/kg ww

Additional information

Measured bioconcentration factors (BCF) obtained in bioaccumulation studies for the substance are not available. However, from the octanol-water partition coefficient a bioconcentration factor can be calculated with the BCFBAF-Program. As the substance is a UVCB-substance, 2-[2-(2-hydroxyethoxy)ethoxy]ethyl 2-hydroxyethyl phthalate was used as the representative of this UVCB-substance for calculation. Taking the measured logKow of 1.6 into account a BCF of 2.9 is estimated by the program. This value is supported by the logKow, indicates that the substance has no potential for bioaccumulation.
