Description of key information

BCF values ranged from a low of 2 up to a high of 1000 L/kg ww, with BCFs increasing with increasing alkyl chain lengths.

Key value for chemical safety assessment

BCF (aquatic species):
87 L/kg ww

Additional information

The bioaccumulation potential of a series of LAS substances was evaluated in flow-through studies with fathead minnows.Results show that the bioconcentration potential of LAS is low and is decreased by environmental processes such as biodegradation and absorption, which reduce aquatic concentrations. BCF values ranged from a low of 2 up to a high of 1000 L/kg ww, with BCFs increasing with increasing alkyl chain lengths. The key value based on all the studies is 87 L/kg ww.
