Rhizoremediation and Phytoremediation Action In The Bioremediation Of PCB-Contaminated Soil

Abstract

-This paper described the biological methods of the cleaning of the environment especially our soil that has been receiving increasing attention especially in the past two decades. Bacteria, plants, and fungi have been the natural detoxification agents for contaminants in the environment. Substantive research in this field of study sparked as a result of the shortcomings of the conventional methods of remediation of POPs including PCBs. Although PCBs and other POPs have continued to be less responsive to various bioremediation strategies, however recent studies have proven that the combination of plants and microorganism in the right proportions and technique, could lead to the detoxification of PCBs in the environment. In this paper, rhizo/phytoremediation carried out synergistically was agued as the most effective biological method for the remediation of PCB contaminated soil. Rhizoremediation and phytoremediation was reported to both play their individual role and has its specific advantages in the remediation of PCBs, but each has certain demerits and could be provided for by the effective utilization of the symbiotic relationship of both plants and microbes. Different methods of PCB remediation was discussed including their merits and demerits, narrowing to the biological remediation. However, the advantages of harnessing rhizoremediation combined with phytoremediation for an effective PCB remediation was elucidated.
