Applicant's summary and conclusion
- Conclusions:
- Calculations with EPA EPIWIN (v4.10) BCFBAF Program (v3.01) for all possible constituents showed a maximum for the Diglycerol-mono-C18-unsat-ester with Log BCF (regression-based estimate): 1.91 (BCF = 80.9 L/kg wet-wt) and Log BAF (Arnot-Gobas upper trophic): 1.23 (BAF = 17 L/kg wet-wt) which reflects the rapid metabolism. Results for all other constituents are below these values. All values are clearly <2000 L/kg wwt which is the definite criteria for PBT substances and clearly <5000 L/kg wwt which is the definite criteria for vPvB substances.
