Administrative data

Endpoint:
distribution modelling
Type of information:
migrated information: read-across from supporting substance (structural analogue or surrogate)
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: This robust summary was given a reliability of 2, because the data are not measured values for the products listed, but are calculated for representative constituents.

Any other information on results incl. tables

Distribution modeling results are included in the ‘Multimedia distribution modeling results’ tab in the PETRORISK spreadsheet attached to IUCLID Section 13. Based on the regional scale exposure assessment, the multimedia distribution of the substance in 36.32% to air, 0.07% to water, 38.45% to sediment and 25.16% to soil. 

Applicant's summary and conclusion

Conclusions:
The distribution of oxidised bitumen in the environmental compartments, air, water, soil, and sediment, has been calculated using the PETRORISK Model. Compositional analysis of oxidised bitumen using two-dimensional gas chromatography indicates a greater amount of quantifiable constituents compared to other types of bitumen. Therefore (Q)SAR data from oxidised bitumen can be used as a conservative read across for the bitumen category.. Based on the regional scale exposure assessment, the multimedia distribution of the substance is 36.22% to air, 0.07% to water, 38.79% to sediment and 24.91% to soil. Distribution modelling results are included in the ‘Multimedia distribution modelling results’ tab in the PETRORISK spreadsheet attached to IUCLID Section 13.
