Bioaccumulation

This substance has a limited potential to bioaccumulate (based on log Kows ranging from – 1.73 to +0.51@ 20oC), and predicted bioconcentration factors, log BCF = ca. 0.50 (EPIWIN/BCF Program).These values would suggest very low bioaccumulation

potential.

The estimated BCF of 3.162 L/kg wet-wt was measured by calculation from EPI SuiteTM v4.0 Program.

This is Exposure Assessment Tools and Models made from EPA (Environmental Protection Agency).
