Description of key information

No bioaccumulation of n-butylchloride is expected with reported BCF values from 7.6 to 17 with Cyprinus carpio, tested in concentrations of 50 and 500 µg/L.

Key value for chemical safety assessment

BCF (aquatic species):
21 dimensionless

Additional information

According to an OECD 305C GLP-guideline study by the Chemicals Evaluation and Reserach Institute Japan (CERI 1992), there is low bioaccumulation potential of the substance 1-chlorobutane (in purity >99% applied). Cyprinus carpio were exposed to 50 and 500 µg test material/L in a flow-through system, with a 6 hour exposure and 3 hour depuration period. The resulting BCF values determined were in a range of 11 to 17 and 7.6 to 21 based on whole body wet weight respectively.
