free-ion-activity model (FIAM)
A model meant to describe metal-organism interactions determining the uptake, nutrition and toxicity of all cationic trace metals. FIAM assumes that the free metal ion activity reflects the chemical reactivity of the metal, i.e., the extent to what the metal reacts with binding sites on the cell membrane surface, and hence its bioavailability and toxicity
