Phytoremedial efficiency of Chrysopogon zizanioides against domestic wastewater is demonstrated in a constructed wetland. The physiochemical parameters were taken into consideration and variation in such parameters were recorded in a period of six months per year after the introduction of the said plants into the study area (constructed wetland). The physiochemical parameters studied were pH, Electrical Conductivity (EC), dissolved oxygen (DO), Biological Oxygen Demand (BOD), Total Hardness (TH), Chlorides (Cl-), Nitrates (NO3-N), and Phosphates (PO43-). The heavy metals like iron (Fe) and Zinc (Zn) were detected by Atomic absorption spectroscopy (AAS). Changes were recorded in the physiochemical parameters as well as in the content of Fe and Zn during the study period. There have been minor changes in pH however, large increment in DO was observed. The said plants have shown good efficiency for the reduction of pollutants and extraction of heavy metals from domestic wastewater in comparison to a lot of already suggested hyperaccumulator plants. The treated water could be utilized for industrial processes, household activities, and irrigation purposes.
