Additional information

An estimated BCF is 70.79 by BCFWIN Model based on log Kow =4.78 (US EPA, 2011). Bioconcentrations of total C12-LAS in fathead minnows (Pimephales promelas), channel catfish (Ictalurus punctatus), andamphipod (Hyalella azteca) were investigated during 32 days. At 32 days, total C12-LAS bioconcentration factors (BCFs) for the three species ranged from 36 to 119 (Versteeg and Rawlings, 2003).These experimental and estimated BCF values suggest that Calcium dodecylbenzenesulphonate

 has a low potential for bioaccumulation.


This substance has a limited potential to bioaccumulate (based on log Kow used by BCF estimates: 4.78, and predicted bioconcentration factors, log BCF = 1.850 (EPIWIN/BCF Program).

The estimated BCF of 70.79 L/kg wet-wt was measured by calculation from EPI SuiteTM v4.1 Program.

These values would suggest very low bioaccumulation potential.
