Cadmium in soils and plants is the basic part of the Cd cycle in the food chain and the main pathway of Cd entry in man is through food. A series of greenhouses experiments were conducted to determine (1) Cd absorption by plants via foliar and root systems and its translocation into the seed; (2) vegetative growth and Cd concentration of crops as influenced by soil-applied Cd; and (3) the relative uptake of Cd by various vegetative crops. The concentration of Cd in the vegetable crops studied varied considerably depending on the plant species. Highest Cd concentration was found in lettuce, while lowest occurred in green peppers and radish roots. Results also showed that Cd absorption via foliage is not as serious as uptake through the root systems from contamination of soils. 5 figures, 1 table.
