Advances in remediation of heavy metal contaminated soil and water by Leersia hexandra Swartz

Heavy metal pollution is extremely harmful to human beings. Looking for an efficient and environmentally friendly treatment method is the focus of current research. Using plants to treat contaminated water and soil has proven to be an effective and environmentally friendly method. Leersia hexandra Swartz is a chromium hyperaccumulator, and it can also enrich copper and nickel. Since the super enrichment characteristics of Leersia hexandra Swartz were discovered, many scholars have poured into the research on Leersia hexandra Swartz. This article will give an overview of the current application status of Leersia hexandra Swartz’s purification of polluted water and soil, analyze the methods and principles used, and discuss the future development direction of Leersia hexandra Swartz’s plant remediation technology.

Study on the Potential of Hyperaccumulator Leersia hexandra swartz to Repair Chromium Contamination of Heavy Metals

In order to control the environmental pollution caused by chromium better, this paper summaries the study about the accumulation charac-teristics, tolerance mechanism, detoxification mechanism and enrichment efficiency of chromium in Leersia hexandra swartz in recent years. It concluded that Leersia hexandra swartz has considerable potential for remediation of polluted environment, especially large-area, low-concentration polluted water, and prospects of its future research direction.
