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.
