Summary The influence of water‐borne iron (500 μg × 1 ‐1 and 2 mg × 1 ‐1 ) on the liver of Poecilia reticulata is studied by means of electron microscopy. The uptake and effect of iron is affected by a. the chemical speciation of the metal: Iron complexed with tri‐polyphosphates is more deleterious than inorganic Fe 3+ ; b. the nutritional status of the fish: In food‐deprived Poecilia reticulata iron is absorbed and enhances starvation‐induced liver damage. In fed animals, there is no uptake at all. Mild alterations of hepatocyte ultrastructure are attributed to an unspecific stress response.
