Research Progress on Remediation of Soil Heavy Metal Pollution by Garden Plants

Abstract

In recent years, the momentum of global industrialization has been rapid, but the ensuing heavy metal pollution problems cannot be ignored. Remediation of heavy metal pollution in soil is a difficult project. The physical and chemical remediation technology used in the past has high cost and is easy to cause secondary pollution. Therefore, the increasingly mature bioremediation technology has become a hot spot, especially the plant remediation technology. According to the research at this stage, it is found that a variety of plants have a targeted enrichment effect on different types of heavy metals, and most plants are common, easy to cultivate, inexpensive, and common in garden plants. Therefore, while implementing garden plants to repair heavy metal pollution in the soil, it also has the effect of urban beautification.
