Description of key information

The fate of oleic acid, copper salt in the environment is most accurately evaluated by separately assessing the fate of its constituents copper cations and oleate anions.

The concept of biodegradation is not applicable to copper cations since metals are not degraded. However as a result of naturally occurring geochemical processes metal ions can get removed from the water column. Information on “changes in copper speciation, removal from the water-column and the potential of copper remobilization from sediments” are considered as equivalent to “biodegradation of organic substances. In addition, available data point to a ready biodegradability of oleic acid (i.e. C18- fatty acid) under aerobic conditions. Thus, oleic acid, copper salt is not expected to persist in solutions since the moieties of oleic acid, copper salt are biodegraded or removed from the water column.
