| Abstract: | 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. |
