Heavy metal pollution is one of most toxic pollutions and cause serious threat to organisms as well as the environment. The tremendous increase in industrialization and other anthropogenic activities magnify the rate of heavy metal pollution. The present study reveals the heavy metal pollution assessment in Kadalundi Vallikunnu Community Reserve (KVCR), a scheduled community reserve of Kerala, India. The results from the study indicate that the heavy metal pollution index of KVCR was less because of the mangrove cover in this region. KVCR is endowed with different mangroves and it plays a significant role in controlling the heavy metal pollution and water quality. The higher Importance Value Index and Relative Importance Value Index was shown in the case of Avicennia officinalis, followed by Acanthus ilicifolius and the lowest values of these indices were observed in the case of Sonneratia alba. The less accumulation of heavy metals in the soil sediments was due to the potential of mangrove species for effective absorption of toxic metals from the soil sediments. Mangrove vegetation in the wetlands is potent phytoremediators and can play a significant role in phytoremediation of wetlands. The high BCF value of A. ilicifolius indicates its suitability for heavy metal remediation in wetlands. Eco restoration of heavy metal polluted wetlands using mangroves is a promising and sustainable solution for heavy metal pollution in such ecologically fragile areas.

重金属污染是最有毒的污染之一，对生物以及环境造成严重威胁。工业化和其他人为活动的急剧增加，扩大了重金属污染的速度。本研究揭示了在印度喀拉拉邦的预定社区保护区Kadalundi Vallikunnu社区保护区（KVCR）中的重金属污染评估。研究结果表明，由于该地区的红树林覆盖，KVCR的重金属污染指数较小。KVCR拥有不同的红树林，在控制重金属污染和水质方面发挥着重要作用。Avicennia officinalis的重要性指数和相对重要性指数较高，其次是在百日草（Sonneratia alba）的情况下观察到了Acanthus ilicifolius和这些指标的最小值。重金属在土壤沉积物中的积累较少是由于红树林物种具有有效吸收土壤沉积物中有毒金属的潜力。湿地中的红树林植被是有效的植物修复剂，可以在湿地的植物修复中发挥重要作用。A的BCF值较高。ilicifolius表明其适用于湿地中的重金属修复。使用红树林对重金属污染的湿地进行生态修​​复是解决此类生态脆弱地区重金属污染的有前途且可持续的解决方案。
