Mangroves are one of the significant categories of coastal vegetation, distributed in the shorelines of tropical and subtropical regions and performing a dynamic role in coastal ecosystems. The recent developments of coastal cities, industrialization, unplanned recreational activities and expansion of aquaculture at mangrove areas in various regions of the world have generated a threat on such significant ecosystems. Nevertheless, the mangrove vegetation has some adaptive features to mitigate the pollution. These ecosystems act as physical, chemical and biological barriers for the transference of pollutants. They play a vital role in trapping sediments; assimilate the excess nutrients by phyto- or bioremediation of toxic substances. The earlier studies revealed that mangroves can act as possible phytoremediators. They absorb a considerable quantity of toxic metal ions and store them in various parts such as stems and roots, consequently evade the transmission of heavy metal ions. In addition, the mangrove associated microorganisms are responsible for remediation of numerous toxic contaminants present within the mangroves. In view of the above, the present chapter offers a comprehensive discussion on the role of mangrove vegetation on abatement of pollutants. |
