BCFBAF v 3.01 Summary

 Log BCF (regression-based estimate)= 0.50 (BCF = 3.16 L/kg wet-wt)

Biotransformation Half-Life (days) = 0.00036 (normalized to 10 g fish)

Log BAF (Arnot-Gobas upper trophic) = -0.05 (BAF = 0.893 L/kg wet-wt)

Log Kow (experimental)= not available from database

Log Kow used by BCF estimates = -2.33

 

Equation Used to Make BCF estimate:

Log BCF = 0.50 (Ionic; Log Kow dependent)

 

Estimated Log BCF = 0.500 (BCF = 3.162 L/kg wet-wt) BCFBAF v 3.01 Summary
