title: Metabolic interactions between metals and metalloids.
abstract: The experimental evidence obtained with laboratory animals which shows that the toxicities of lead, cadmium, and mercury can be increased by deficiencies of certain essential nutrients such as calcium, iron, zinc, and selenium is briefly reviewed. An idealized theoretical model which indicates the possible influence of multiple nutritional deficiencies on the toxicity of a heavy metal is presented. It is suggested that multiple marginal nutritional deficiencies may be of importance in determining the response of humans to the toxic effects of various heavy metal pollutants.
