Administrative data

Endpoint:
distribution modelling
Type of information:
calculation (if not (Q)SAR)
Remarks:
Estimated by calculation
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: This robust summary is given a reliability rating of 2, because the data are not measured values for the products listed, but are calculated for representative constituents.
Justification for type of information:
Hydrocarbons, C9-C10, aromatics, >1% Naphthalene are a combination of Hydrocarbons, C9 Aromatics and Hydrocarbons, C10-C12 Aromatics. Read across data is available for Hydrocarbons, C9 Aromatics and Hydrocarbons, C10-C12 Aromatics and the worst case scenario for each end point has been presented.

Distribution modeling results are included in the 'Multimedia distribution modeling results' tab in the PETRORISK spreadsheet attached to Section 13 of the CSR. Based on the regional scale exposure assessment, the multimedia distribution of the substance in 92.9% to air, 3.5% to water, 1.9% to sediment and 1.8% to soil.

Conclusions:
The distribution of the substance in the environmental compartments, air, water, soil and sediment, has been calculated using the PETRORISK Model, version 5.2. Based on the regional scale exposure assessment, the multimedia distribution of the substance is 92.9% to air, 3.5% to water, 1.9% to sediment and 1.8% to soil. Distribution modelling results are included in the 'Multimedia distribution modelling results' tab in the PETRORISK spreadsheet attached to Section 13 of the dossier.
Executive summary:

This data is being read across from the source study that tested Hydrocarbons, C9, aromatics based on analogue read across.

The distribution of the substance in the environmental compartments, air, water, soil and sediment, has been calculated using the PETRORISK Model, version 5.2. Based on the regional scale exposure assessment, the multimedia distribution of the substance is 9 2.9% to air, 3.5% to water, 1.9% to sediment and 1.8% to soil. Distribution modelling results are included in the 'Multimedia distribution modelling results' tab in the PETRORISK spreadsheet attached to Section 13 of the dossier.
