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 Sodium dodecylbenzenesulfonate has a low potential for bioaccumulation.
