用矿物材料改良土壤以去除污染物既古老又新颖。虽然矿物改良剂在农业中已经使用了几十年，但各种天然和再加工材料的新应用正在出现。通过将污染物封存在固相中或固相上并降低其分配到水或空气中的能力，修正剂可以降低人类或生物群接触的风险。各种矿物类型通常用于改良受污染的土壤，具有不同的分子级螯合模式。监管、社会和经济因素也影响采用矿物改良剂作为处理技术的决定。
Amending soils with mineral-based materials to immobilize contaminants is both old and new. Although mineral amendments have been used for decades in agriculture, new applications with a variety of natural and reprocessed materials are emerging. By sequestering contaminants in or on solid phases and reducing their ability to partition into water or air, amendments can reduce the risk of exposure to humans or biota. A variety of mineral types are commonly used to amend contaminated soils, with different modes of molecular-scale sequestration. Regulatory, social, and economic factors also influence decisions to employ mineral amendments as a treatment technology.
