Leather tannery industry discharged wastewater containing chromium to the nearby river. The presence of chromium in excess of the limit pollutes the environment and could harm animal and human health. In this study, we examined wetland plants i.e. Typha angustifolia L., Canna indica L. and Hydrocotyle umbellata L. for their effectiveness in remediating chromium in an artificial wetland system within nine days period. Chromium compound, K 2 Cr 2 O 7 , was used with a variation in concentration of 0, 10, 30 and 50 mg/L. All three plants survived until the 9 th day. The plant with the highest relative growth was C. indica , whereas plants which showed highest chromium accumulation and bioconcentration factor (BCF) was H. umbellata . Chromium accumulated more in the root than in the shoot (TF <1). Plant with highest efficiency in reducing chromium in medium was T. angustifolia (99.78%) grown in 50 mg/L chromium. The efficiency of C. indica and H. umbellata were 99.67% and 86.36%, respectively. The three plants showed a good potential of phytoremediation for wastewater containing chromium.
