Applicant's summary and conclusion

Conclusions:
The estimated bioconcentration factor (BCF) for 1,3-dihydro-1-oxoisobenzofuran-5-carbonitrile is 3.2 which does not exceed the bioconcentration threshold of 1000. Thus it is concluded that 1,3-dihydro-1-oxoisobenzofuran-5-carbonitrile 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 1,3-dihydro-1-oxoisobenzofuran-5-carbonitrile is 3.2 which does not exceed the bioconcentration threshold of 1000. Thus it is concluded that 1,3-dihydro-1-oxoisobenzofuran-5-carbonitrile is not expected to bioaccumulate in the food chain because it does not exceed the BCF criteria.
