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
