摘要：

Three-year pot experiments, carried out in a greenhouse, and laboratory investigations proved that the introduction of synthetic zeolites into lead-contaminated soils led to a reduction in the lead content of plants and thus contributed to a reduction in lead in the nutrient cycle. Lettuce leaves grown on a lead-contaminated soil amended with zeolites were 49-73% lower in Pb content than those on soils with no zeolites added. For grasses, these reductions were 47-77%, for the aboveground parts of oats 58-68%, for beet leaves 62%, and for beet roots 26-83%.
