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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
