Cadmium |
 Cadmium: The typical daily dietary intake of
cadmium is 10 to 20 µg. Significant sources of cadmium include
shellfish, grains (especially those grown on high cadmium soils) and
leafy vegetables. Cadmium has a long half-life in the body and thus
high intakes can lead to accumulation resulting in damage in some
organs, especially the kidney. The Reference Dose (RfD) (safe daily
intake over a lifetime) for cadmium is 0.5 µg per kg body weight.
