摘要: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.
