Abstract—

This article summarizes the authors’ 10-year study of soil phytoremediation in an anthropogenically contaminated area around a copper smelter in the Valparaiso region of central Chile. It analyzes the risk that contaminated soils pose to public health. Phytostabilization and phytoextraction were considered as the main methods of soil phytoremediation. A study conducted in an industrially contaminated area around a copper smelter found that the application of soil amendments eliminated the factors that inhibited plant growth and allowed for natural regeneration. It was also demonstrated that a single application of a soil amendment (lime or a mixture of lime and compost) was sufficient to establish a stable, self-sustaining ecosystem that was maintained for at least six years. Our study also found that the main disadvantage of the phytoextraction method, which is the long time required to remove the metal from the soil, makes it unfeasible in Chile given the absence of copper hyperaccumulator plants in this country.

智利铜冶炼污染土壤的植物修复：十年研究结果

摘要-

本文总结了作者对智利中部瓦尔帕莱索地区铜冶炼厂周围人为污染区域土壤植物修复的 10 年研究。它分析了受污染的土壤对公众健康构成的风险。植物稳定和植物提取被认为是土壤植物修复的主要方法。在铜冶炼厂周围的工业污染区进行的一项研究发现，土壤改良剂的应用消除了抑制植物生长的因素，并允许自然再生。还证明单次施用土壤改良剂（石灰或石灰与堆肥的混合物）足以建立一个稳定的、自给自足的生态系统，并至少维持六年。
