Phototransformation in air
Administrative data
Link to relevant study record(s)
- Endpoint:
- phototransformation in air
- Type of information:
- (Q)SAR
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Results obtained for representative components of the substance, by calculations with a valid QSAR
- Justification for type of information:
- Standard photolysis 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. The use of QSAR in this instance is justified because:
- the results are obtained from a QSAR model whose scientific validity has been established - Guideline:
- other: Reach guidance on QSAR - R.6
- Deviations:
- no
- Principles of method if other than guideline:
- The phototransformation in air of representative constituents of the substance was calculated using AOPWIN v.1.92
- GLP compliance:
- not specified
- Specific details on test material used for the study:
- Details on properties of test surrogate or analogue material:
No test surrogate - Estimation method (if used):
- The phototransformation rates and half-lives were calculated using AOPWIN v1.92

- Reaction with:
- OH radicals
- Rate constant:
- >= 0 - <= 0 cm³ molecule-1 s-1
- Transformation products:
- not specified
- Results with reference substance:
- Not applicable
- Conclusions:
- The half-lives of selected constituents of Hydrocarbons, C12-C18, isoalkanes, cyclics 2-30% aromatics were in the range 0.09 and 2.38 d.
- Executive summary:
This substance is a UVCBs. Therefore, the phototransformation in air was estimated from the AOPWIN v1.92 calculations of phototransformation of selected hydrocarbons likely to be constituents of this substance as identified by PETRORISK.
The phototransformation rate for this substance is in the range 4.50 x 10^-12 and 1.19 x 10 ^-10 cm3/molecule/sec. The half-lives of selected constituents of hydrocarbons, C12 -C18, isoalkanes, cyclics 2 -30% aromatics were in the range 0.09 and 2.38 d.
Reference
Description of key information
This substance is a hydrocarbon UVCBs and the constituent hydrocarbons will exhibit a wide range of photolysis in air values. Standard tests for this endpoint are intended for single substances and are not appropriate for these complex substances as the composition of the total dissolved hydrocarbons will be different from the composition of the parent substance. However, this endpoint is characterized using quantitative structure property relationships for representative hydrocarbon structures that comprise the hydrocarbon blocks used to assess the environmental risk of these substances with the PETRORISK model (see Product Library in PETRORISK spreadsheet attached in section 13). The potential constituents identified by PETRORISK that match the composition of this substance were used to run the AOPWIN model.
The phototransformation rate for this substance is in the range 4.50 x 10^-12 and 1.19 x 10 ^-10 cm3/molecule/sec. The half-lives of selected constituents of hydrocarbons, C12 -C18, isoalkanes, cyclics 2 -30% aromatics were in the range 0.09 and 2.38 d.
