Neurobehavioural effects in rats fed low doses of cadmium and lead to induce hypertension.

Rats given diets supplemented with low doses of cadmium or lead or both elements together showed an increase in cadmium levels within the brain in all supplemented groups. Hypo-activity was noted after 16 months of dietary supplementation with lead or with cadmium and lead. Activity was unaffected by feeding with cadmium alone.
