title: Inactivation of cadmium in contaminated soils using synthetic zeolites.
abstract: The addition of synthetic zeolite pellets to soils contaminated with cadmium significantly reduced the concentrations of cadmium in the roots and shoots of a range of crop plants. Use of synthetic foyazite group zeolites types 4A and 13X, at application rates of 1% by soil weight, caused reductions in cadmium concentrations of up to 86% in leaves of lettuce grown in pots, compared to controls with no added zeolites. The potential of these substances to reduce cadmium entry into the food chain, and as a clean up method, is noted.
