Description of key information
The test substance hydrocarbons, C13-C20, n-alkanes, isoalkanes, cyclics, 40-60% aromatics, is readily biodegradable.
Key value for chemical safety assessment
Additional information
A marine biodegradability study is available for hydrocarbons, C13-C20, n-alkanes, iso-alkanes, cyclics, 40-60% aromatics (Svalheim et al. 2001). The specific oxygen demand after 28 days was 2.122 mg BOD/mg sample for Esticlean AS-OF. This corresponds to a degradation of about 64% relative to the theoretical oxygen demand. Degradation of chemicals in seawater has generally been found to be slower than that in freshwater tests inoculated with activated sludge and sewage effluent, and, therefore, a positive result obtained during 28 (Closed Bottle Method) in the biodegradability in Seawater test can be regarded as evidence of a chemical’s potential for biodegradation in the marine environment. The result obtained for the Esticlean AS-OF indicates that there is a potential for degradation in marine environments. A result of >60% ThOD removal is indicative of potential for ultimate biodegradation in the marine environment. When a chemical attains >60% ThOD removal in a Biodegradability in Seawater test (OECD 306), it can also be expected to fulfil the criteria for ready biodegradability (Eurpean Chemicals Agency 2008).
Further data on biodegradation in freshwater are available for hydrocarbons, C14-C18, n-alkanes, isoalkanes, cyclics, aromatics (2-30%) and hydrocarbons, C16-C20, n-alkanes, isoalkanes, cyclics, aromatics (2-30%). Studies conducted with these analogue substances demonstrate that they are inherently biodegradable in aerobic freshwater systems with a biodegradation potential in the range of 58.7 to 60.7% following standard testing guidelines. Thus, hydrocarbons, C13-C20, n-alkanes, iso-alkanes, cyclics, 40-60% aromatics is not expected to persist in the environment under aerobic conditions.
A justification for the use of mentioned analogue substances for read-across is attached to IUCLID section 13.
