Applicant's summary and conclusion

Conclusions:
The estimated bioconcentration factor (BCF) of Acid Violet 43 is reported as 3.162 L/kg wet-wt, does not exceed the bioconcentration threshold of 2000. Thus it is concluded that Acid Violet 43 is not expected to bioaccumulate in the food chain.
Executive summary:

The estimated bioconcentration factor (BCF) of Acid Violet 43 is reported as 3.162 L/kg wet-wt, does not exceed the bioconcentration threshold of 2000. Thus it is concluded that Acid Violet 43 is not expected to bioaccumulate in the food chain.
