The present study was conducted to evaluate the phytoremediation potential and pollutant removal efficiency of Lemna minor and Pistia stratiotes to treat detergent water. The study was carried for 30 days and at an interval of 5 days, various physicochemical parameters like pH, Conductivity, Total dissolved Solids, Dissolved oxygen, Nitrate, Phosphate, Potassium and Sodium levels were analysed. pH levels were brought to near neutral by both plant species. Lemna minor managed to reduce the concentration of above-mentioned parameters except Phosphate levels which was increased by it and also negatively affected the Dissolved oxygen values by decreasing it. Pistia stratiotes showed a better reducing efficiency by decreasing Conductivity and Total Dissolved Solids by 23.07%, Phosphate by 27.27%, Nitrate by 78.31%, Potassium by 15.28%, Sodium by 12.45% and increased Dissolved oxygen level by 3.3%. All parameters examined were within the permissible limits of WHO and BIS standards. In this experiment Pistia stratiotes was found to be more efficient in pollutant removal and depicted better tolerance towards detergent water. Both the plant species showed optimum growth. Cross- sections of plant parts enabled in understanding waste uptake and trapping by plants during root to shoot transportation.
