Summary of degradation
Abiotic degradation
No data on the hydrolysis of shale oil (light fraction) are available. Based on the properties of the test substance (it is a mixture of various different compounds, not chemically well defined with no main component) a hydrolysis study is technically not feasible.
Biotic degradation
In an inherent biodegradability study to the OECD 302C guideline, at the end of the 28-day exposure period, the mean extent of biodegradation of Shale Oil (middle fraction) was 22%. Thus, some compounds of the test item were biodegradable. However, the major part of the test item was not biodegraded within 28 days of test duration in this inherent biodegradability test. It is considered acceptable to read-across from the middle fraction of shale oil to the light fraction, on the basis that the fractions were shown to be compositionally similar from the analytical data available.
On the basis of the results of the study for the purpose of the risk assessment it has been concluded that Shale Oil (light fraction) is: inherently biodegradable, not fulfilling specific criteria
Volatilisation
No data available.
Distribution modelling
No distribution modelling data exist.
Summary of environmental distribution
Data are not available to allow the distribution of Shale Oil (light fraction) within the environment to be modelled. In Section 1.3 the solubility of Shale Oil (light fraction) is reported as 5.74 g/L, the Log Pow as 2.84 and the vapour pressure as 13.5 kPa at 25°C. Based on these properties the substance would be expected to be primarily distributed within air with lower quantities in water and minimal association with soils/sediments.
Summary and discussion of bioaccumulation
Aquatic bioaccumulation
In accordance with column 2 of REACH Annex IX, Bioaccumulation in Aquatic Species (required in section 9.3.2) does not need to be conducted as the log Kow is <3 and the chemical safety assessment concludes that the substance is of no immediate concern to the environment. The available data are adequate for classification and labelling purposes and PBT assessment, so no further testing is required. Also direct and indirect exposure of the aquatic compartment is unlikely.
Terrestrial bioaccumulation
No data are available on terrestrial bioaccumulation. However, the bioaccumulation potential of the substance is predicted to be low. The risk of terrestrial bioaccumulation is therefore negligible.
Secondary poisoning
Shale Oils (light fraction) present a low risk with regard to secondary poisoning due its low bioaccumulation potential
