In the assessment of the environmental fate and pathways of silver behenate, a read-across approach from data for the metal cation and the organic anion is followed. This read-across strategy is based upon the assumption that upon release to the environment and dissolution in aqueous media, silver behenate will completely dissociate and only be present in its dissociated form, i.e. as silver cation and behenate anion even though T/D test demonstrates that only a minor part of the substance dissolves in water in silver cation and behenate anion after 7 days.

Upon dissolution and dissociation of silver behenate into silver and behenate, both constituent ions will each show its proper (bio)degradation, bioaccumulation and partitioning behavior in the environment. The environmental fate and behavior for the metal and organic moieties is predicted to be clearly different from each other, resulting in a different relative distribution over the environmental compartments (water, air, sediment and soil).
