The use of low-cost and environmental safety amendments for the in situ immobilization of heavy metals has been investigated as a promising method for contaminated soil remediation. Natural materials and waste products from certain industries with high captive capacity of heavy metals can be obtained and employed. Reduction of extractable metal concentration and phytotoxicity could be evaluated and demonstrated by the feasibility of various amendments in fixing remediation. In this review, an extensive list of references has been compiled to provide a summary of information on a wide range of potentially amendment resources, including organic, inorganic and combined organic-inorganic materials. The assessment based on the economic efficiency and environmental risks brought forth the potential application values and future development directions of this method on solving the soil contamination.
使用低成本且环境安全的改良剂对重金属进行原位固定，已作为一种有前景的污染土壤修复方法进行了研究。可以获取并利用具有高重金属俘获能力的天然材料和某些工业的废品。通过各种改良剂在固定修复中的可行性，可以评估并证明可提取金属浓度的降低和植物毒性的降低。在本综述中，已汇编了大量参考文献，以提供有关各种潜在改良资源的信息摘要，包括有机、无机以及有机 - 无机复合材料。基于经济效率和环境风险的评估，提出了该方法在解决土壤污染方面的潜在应用价值和未来发展方向。
