Description of key information

Bioconcentration of 1,2-dichloropropane does not appear to occur to a significant extent.  Measured bioconcentration factors (BCF) ranged from 0.5 to 6.9, and are in excellent agreement with calculated values published in several handbooks.  

Key value for chemical safety assessment

BCF (aquatic species):

Additional information

Results from an OECD 305C guideline study on bioconcentration in fish, conducted using flow-through exposures of carp at 0.4 and 0.04 mg/L of 1,2-dichloropropane, demonstrated limited or no potential for 1,2-dichloropropane to bioconcentrate (BCF = 0.5-6.9). The low measured bioconcentration factor is supported by a calculated log BCF of < 1 to 1.29 reported in several handbooks (Howard; McKay et al.).
