In fresh water, silver may form complex ions with chlorides, ammonium (in areas of maximum biological activity), and sulfates form soluble organic compounds such as the acetate and the tartrate become adsorbed onto humic complexes and suspended particulates and become incorporated into, or adsorbed onto, aquatic biota (Boyle 1968). Where decaying animal and plant material are abundant, silver strongly precipitates as the sulfide or combines with humic materials (Smith and Carson 1977).
