Administrative data

Endpoint:
distribution modelling
Type of information:
calculation (if not (Q)SAR)
Adequacy of study:
key study
Study period:
n/a
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: This robust summary was given, a reliability rating of 2, because the data are not measured values for the product listed, but are calculated for representative constituents.
Justification for type of information:
A discussion and report on the read across strategy is given as an attachment in IUCLID Section 13.

Endpoint:
distribution modelling
Type of information:
read-across based on grouping of substances (category approach)

Model:
calculation according to Mackay, Level III
Calculation programme:
PETRORISK Model, version 5.2
Release year:
2 010
Media:
air - biota - sediment(s) - soil - water
Air (%):
0.45
Water (%):
0.95
Soil (%):
8.8
Sediment (%):
89.8

Distribution modelling results are included in the 'Multimedia distribution modeling results' tab in tthe PETRORISK spreadsheet attached to Section 13 of the CSR. Based on the regional scale exposure assessment, the multimedia distribution of the substance is 0.42 % to air, 0.95 % to water, 90 % to sediment and 0.0008 % 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 0.42 % to air, 0.95 % to water, 0.0008 % to soil and 90 % to sediment. Distribution modeling results are included in the 'Multimedia distribution modeling results' tab in the PETRORISK spreadsheet attached to IUCLID section 13.
Executive summary:

The distribution of the substance in the environmental compartments, air, water, soil, and sediment, has been calculated using the PETRORISK Model, version 5.2. Computer modeling is an accepted method for estimating the environmental distribution of chemicals. Distribution modeling results are included in the 'Multimedia distribution modeling results' tab in the PETRORISK spreadsheet attached to IUCLID section 13.
