Water Plant

Many plants are capable of accumulating heavy metals (called hyperacumulators), one of which is the water hyacinth Eichhornia crassipes Mart. The roots of this water plant naturally absorb pollutants, including heavy metals such as Pb, Hg, Zn, Co, Cd, and Cu and can be used for wastewater treatment. The aim of this study was to assess the influence of heavy metals on growth and development of water hyacinth and to determinate the uptake capacity of heavy metals of this species. It was evaluated for its effectiveness in reducing pollution potential in wastewater. From the combination of experimental factors 11 variants resulted. The results showed that Eichhornia absorbed a high quantity of Pb (504 mg/kg dry matter) and Cu (561 mg/kg dry matter) in their roots. More Cu accumulated in the root compared to Pb. The level of Zn absorption was lower in roots (84 mg/kg dry matter) and also in stem plus leaves (51 mg/kg dry matter). A high quantity of Cd (281 mg/kg dry matter) was removed from stem plus leaves of Eichhornia while the level of Co was very low (45 mg/kg dry matter). Regarding the growth and development of this plant it was found that in tanks with Pb plants had a better development and had flowers also, and in the case of Cd, Co, Cu at a double dose of maximum admissible limits, the plants died and the growing period was shorter.

Metal mercury (Hg), has the chemical name hydragyrum which means liquid. Mercury metal is represented by Hg. In the periodic chemical elements Hg rank (NA) 80 and have atomic weights (BA 200,59). Rat Purun (Eleocharis dulcis) and water hyacinth (Eichhorniacrassipes) are plants that are widely found in tidal swamp land. Both plants can be used as organic fertilizer, biofilter, and absorb toxic elements such as heavy metals Lead (Pb), Iron (Fe), Mercury (Hg), Sulphate (SO4). This study aims to determine the ability of rat purun plants (Eleochalisdulcis) and water hyacinth (Eichhorniacrassipes) in reducing mercury (Hg) levels in water and to determine the effectiveness of rat purun plants (Eleochalisdulcis) and water hyacinth (Eichhorniacrassipes) in absorbing mercury Hg. Sample analysis was carried out at the Bandar Lampung Standardization Research Center.The results obtained by rat purun plants (Eleochalisdulcis) can reduce mercury levels (Hg). The effectiveness of reducing heavy metal mercury (Hg) is 97.88%. Water hyacinth plants (Eichhorniacrassipes) have effectiveness in reducing heavy metals mercury (Hg) which is equal to 96.66%.

Eichhornia crassipes is a floating macrophyte. It is capable of assimilating large quantities of toxic metals, some of which are essential for plant growth. Water Hyacinth grows rapidly in water with a high level of nutrients like nitrogen and phosphorous. The plants have been shown to absorb trace elements such as Silver (Ag), Lead (Pb), Cadmium (Cd) and Copper (Cu) reported by Lu et al [1]. The purpose of this study is to determine the distribution of heavy metals in different parts of the Water Hyacinth . Such a detail study has been taken for the first time. It is expected that the metal distribution within the plant species would be a representation of the concentration and distribution of the water in which it is found. Plants have the ability to accumulate non-essential and essential trace elements and this ability could be harnessed to remove pollutant metals from the environment. Aluminum, cadmium, calcium, copper, iron, lead, magnesium and zinc have been found in different amounts in roots, stems, leaves and flowers.

Plant Sample

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.
