Due to the low vapour pressure of oleamide, a Henry’s Law Constant of 0.0928 pa m³/moland the rapid half-life in air calculated according to SRC AOPWIN to be 4.8 hours, it is concluded that oleamide will not accumulate in air and will not be transported through the vapour phase into other environmental compartments in relevant amounts. Thus, air is not a likely route of environmental contamination and no accumulation and subsequent deposition of oleamide is to be expected.

The result of the Mackay LEVEL 1 calculation shows that, over time the substance will preferentially distribute into soil and sediment. The measured log Koc of 5.18 indicate also a potential to adsorb to soil and sediment. However, due to the ready biodegadability, the substance will not persist in these compartments and as the test substance is poorly soluble in water (< 0.1 mg/L) it is expected that sediments are, if at all, only exposed to very small amounts of the test substance, as amounts will be present in wastewater, they will be eliminated in common wastewater treatment plants to a large amount due to the readily bioegradability of oleamide.

The overall environmental fate profile indicates that oleamide is not to be persistence in the environment.
