The overall environmental fate profile indicates that amides, C16-C18 (even numbered) is not to be persistence in the environment.

Due to the low vapour pressure of amides, C16-C18 (even numbered) , the low Henry’s Law Constant and the rapid half-life in air calculated according to AOPWIN v1.92 (2010) to be 0.5-0.6 days, it is concluded that amides, C16-C18 (even numbered) 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 amides, C16-C18 (even numbered) is to be expected.

Binding potential to the solid soil phase (e. g. clay) or sediment is expected due to the Koc of 4.1 -4.6. But an exposure of sediment is unlikely as the substance is readily biodegradable and insoluble in water. Therefore, and as predicted by EPISuite, the substance will tend to remain in the STP facilities (Total removal of 94% (estimation)). Thus, only small amounts will be released into the environment and a relevant exposure to soil and sediment is not expected.
