Description of key information
Biodegradation in water: screening tests
Hydrocarbons, C14-C20, aliphatics (≤2% aromatics) were found to be readily biodegradable (biodegradation > 60% ThOD) in an OECD 306 ready biodegradability test. Taking into account that all those substances have been found biodegradable in seawater 306 test, this is taking over all screening tests results and lead to the conclusion that these substances have the same properties and are therefore considered readily biodegradable.
Hydrocarbons, C14-C18, n-alkanes, isoalkanes, cyclics, ≤2% aromatics was biodegraded 74% at day 28 in a Closed Bottle test. Hence this substance should be classified as readily biodegradable.
Hydrocarbons, C14-C17, n-alkanes, <2% aromatics was found to be readily biodegradable under the conditions of an OECD 301 study meeting the 10-d window.
The biodegradation prediction by BIOWIN does not lead to the conclusion that Icosane would be persistent.
Biodegradation in water: simulation tests
Several studies conducted according to OECD 306 guideline were available and all concluded to the ready biodegradability of C14-20 Aliphatics (≤2% aromatic)i n seawater according to OECD criteria for biodegradability in seawater.
Biodegradation in sediment: simulation tests
C14-20 Aliphatics (≤2% aromatic) are readily biodegradable. Therefore, simulation tests in sediment are not required.
Biodegradation in soil
Hydrocarbons C14-C20, aliphatics, ≤2% aromatics have been shown to be readily biodegradable. According to Column 2 of Annex IX on the standard information requirements, simulation testing on ultimate degradation in soil does not need to be conducted if the substance is readily biodegradable.
Additional information
Hydrocarbons C14-20 Aliphatics (≤2% aromatic) were found to be readily biodegradable (biodegradation in natural seawater > 60% ThOD) in OECD 306 closed bottle test (van Ginkel, 2009a) as well as in OECD 301 ready biodegradability test (Cidaria, 1994). Therefore, these substances are considered readily biodegradable and no further biodegradation studies are deemed necessary.
