Abstract

The release of industrial effluents into natural wetlands is a ubiquitous problem worldwide, and phytoremediation could be a viable option for treatment. The present study assessed metal accumulation strategies of three dominant emergent plants [Colocasia esculenta (L.) Schott, Scirpus grossus (L.) f., and Typha latifolia L.] growing in a wetland contaminated with coke-oven effluent. Metals concentration (mg kg-1) in wetland sediment followed the order Mn (408) > Cu (97) > Co (14.2) > Cr (14) > Cd (2.7). Plant tissues (root and shoot) showed metal-specific accumulation at different extents due to plant response against metal utility or toxicity. Bioconcentration factor (BCF) and translocation factor (TF) of metals in plants revealed Cd and Mn pollution could be remediated through phytoextraction (BCF > 1 and TF > 1); however, Co, Cu, and Cr pollution could be remediated through phytostabilization (BCF > 1 and TF < 1).
