POTENTIAL OF WATER HYACINTH (EICHHORNIA CRASSIPES L.) FOR PHYTOREMEDIATION OF HEAVY METALS FROM WASTE WATER
Keywords:Water hyacinths, phytoremediation, cadmium, arsenic, mercury
The present study was carried out to determine the potential for phytoremediation of water hyacinth (Eichhornia crassipes) plant for Cadmium (Cd), Arsenic (Ar), and Mercury (Hg) absorption. The samples were collected from Dhamthal, Zafarwal and Narowal. The plant samples were cut into their parts and dried at room temperature for 25-30 days until they were fully dried. The change in fresh weight and dry weight was examined. The data of collected samples was recorded and statistically analyzed, which revealed the significance of results for different localities. The lower coefficient of variation was recorded for all studied traits which revealed that there was consistency among the results for different localities. For our study the plant's percentage removal of metals was determined using atomic absorption spectroscopy in plant sample as well as water sample. Metal uptake happened at variable degrees. The water hyacinth uptake the largest metal uptake per dry weight of water hyacinth was 166.25ppm for cadmium and the smallest 0.032ppm was for mercury. In water sample highest amount of metal was 177.25ppm for cadmium and lowest 0.012ppm was for arsenic. It was found from our study that the water hyacinth (Eichhornia crasssipes) uptake cadmium (cd) metal from sewage water in highest amount as compare to arsenic and mercury. It was suggested that the use of water hyacinth plant may be helpful to remove heavy metals from waste water to minimize the heavy metal pollution of water.
