Description of key information
Additional information
Phototransformation in air is characterized using quantitative structure property relationships for representative hydrocarbon structures that comprise the hydrocarbon blocks used to assess the environmental risk of this substance with the PETRORISK model (see Product Library in PETRORISK spreadsheet attached to IUCLID Section 13).
Hydrocarbons, C13-C20, n-alkanes, isoalkanes, cyclics, 40-60% aromatics are composed of carbon and hydrogen and are not amenable to hydrolysis because of their molecular structure and the chemical reaction required for this type of transformation to occur.
A marine biodegradability test available for hydrocarbons, C13-C20, n-alkanes, iso-alkanes, cyclics, 40-60% aromatics demonstrates that the substance is readily biodegradable (Svalheim et al. 2001). This test resulted in 64% ThOD removal. Since it is known that biodegradation in seawater is generally slower than in freshwater, a substance can be considered readily biodegradable if the degradation rate exceeds 60% ThOD (European Chemical Agency 2008, Guidance on information requirements and chemical safety assessment Chapter R.7b: Endpoint specific guidance). Results obtained in freshwater biodegradation studies with analogue substances demonstrate them to be inherently biodegradable (CEFIC 1995a, 1995b, EMBSI 1996). The substance, hydrocarbons, C13-C20, n-alkanes, iso-alkanes, cyclics, 40-60% aromatics, is thus not expected to persist in the environment. For reasons explained in endpoint summary of section 6 a split of classification is done for this substance based on biodegradation results.
Substance is a hydrocarbon UVCB. Standard tests on bioaccumulation are intended for single substances and are not appropriate for this complex substance. However, this endpoint has been calculated for representative hydrocarbon structures using the BCFWIN v2.16 model within EPISuite 3.12 and default algorithms in the EUSES model as input to the hydrocarbon block method incorporated into the PETRORISK model. The predicted BCFs for hydrocarbons are generally overly conservative since biotransformation is not quantitatively taken into account. Therefore, indirect exposure and resulting risk estimates predicted by PETRORISK are likely to be overestimated.
The distribution of the substance in the environmental compartments, air, water, soil, and sediment, has been calculated using the PETRORISK Model, version 5.0. Computer modelling is an accepted method for estimating the environmental distribution of chemicals. Distribution modelling results are included in the 'Multimedia distribution modelling results' tab in the PETRORISK spreadsheet attached to Section 13 of IUCLID.
