CHEM : C.I. FOOD BLACK 1
MOL FOR: C28 H21 N5 O11 S3
MOL WT : 699.69
--------------------------------- BCFBAF v3.01 --------------------------------
Summary Results:
Log BCF (regression-based estimate): 0.50 (BCF = 3.16 L/kg wet-wt)
Biotransformation Half-Life (days) : 0.0243 (normalized to 10 g fish)
Log BAF (Arnot-Gobas upper trophic): 0.96 (BAF = 9.04 L/kg wet-wt)
Log Kow (experimental): not available from database
Log Kow used by BCF estimates: 2.85
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)
Applicant's summary and conclusion
- Conclusions:
- The estimated bioconcentration factor (BCF) for C.I. FOOD BLACK 1 is 3.162 L/kg, that does not exceed the bioconcentration threshold of 2000. Thus it is concluded that C.I. FOOD BLACK 1 is not expected to bioaccumulate in the food chain because it does not exceed the BCF criteria.
- Executive summary:
The estimated bioconcentration factor (BCF) for C.I. FOOD BLACK 1 is 3.162 L/kg, that does not exceed the bioconcentration threshold of 2000. Thus it is concluded that C.I. FOOD BLACK 1 is not expected to bioaccumulate in the food chain because it does not exceed the BCF criteria.
