The present study was focused on field research to examine the phytoremediation potential of naturally grown Eichhornia crassipes in fly ash (FA) pond. Field results indicate the efficiency of E. crassipes for remediation of heavy metals from FA pond. The bioconcentration factor trend was Cr (3.75) > Cu (2.62) > Cd (1.05), and Cu (1.35) in root and stem, respectively. The survival and abundance growth of E. crassipes in the circumstance of heavy metal enriched FA pond is another highlight of the present research that reveals its toxitolerant characteristics. Thus, this lesson on phytoremediation proved that E. crassipes is a potential accumulator of Cu, Cr, and Cd from FA ponds and is a promising species for FA pond's remediation globally.
本研究聚焦于实地研究,以考察天然生长的凤眼莲在粉煤灰(FA)池塘中的植物修复潜力。实地研究结果表明,凤眼莲对从FA池塘中去除重金属具有高效性。生物富集系数趋势为铬(3.75)>铜(2.62)>镉(1.05),而根和茎中的铜分别为(1.35)。在重金属富集的FA池塘环境中,凤眼莲的存活和丰度增长是本研究的另一个亮点,揭示了其耐毒性特征。因此,这一植物修复实例证明,凤眼莲是FA池塘中铜、铬和镉的潜在积累者,是全球FA池塘修复的一个有前景的物种。
