Administrative data

Endpoint:
distribution modelling
Type of information:
(Q)SAR
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Justification for type of information:
Standard biodegradation studies are not applicable to petroleum UVCB substances, therefore in accordance with Annex XI Section 1.3 testing is not scientifically necessary and the endpoint has been fulfilled using QSAR calculations for relevant constituents. PETRORISK is a well documented and peer reviewed model that is widely used across the petrochemicals industry. The registration substance fits within the criteria of the model and there are no reservations about the validity of the model runs. It is expected that this data is reliable with restrictions.

Applicant's summary and conclusion

Conclusions:
The distribution of the substance in the environmental compartments, air, water, soil, and sediment, has been calculated using the PETRORISK Model. Based on the regional scale exposure assessment, the multimedia distribution of the substance is 78.2 % to air, 3.0 % to water, 11.9% to sediment and 6.9 % to soil. Distribution modelling results are included in the ‘Multimedia distribution modelling results' in the PETRORISK report attached to IUCLID Section 13 of the CSR.
