Selection Of

Heavy-metal (HM) pollution is considered a leading source of environmental contamination. Heavy-metal pollution in ground water poses a serious threat to human health and the aquatic ecosystem. Conventional treatment technologies to remove the pollutants from wastewater are usually costly, time-consuming, environmentally destructive, and mostly inefficient. Phytoremediation is a cost-effective green emerging technology with long-lasting applicability. The selection of plant species is the most significant aspect for successful phytoremediation. Aquatic plants hold steep efficiency for the removal of organic and inorganic pollutants. Water hyacinth (Eichhornia crassipes), water lettuce (Pistia stratiotes) and Duck weed (Lemna minor) along with some other aquatic plants are prominent metal accumulator plants for the remediation of heavy-metal polluted water. The phytoremediation potential of the aquatic plant can be further enhanced by the application of innovative approaches in phytoremediation. A summarizing review regarding the use of aquatic plants in phytoremediation is gathered in order to present the broad applicability of phytoremediation.

Potential Parameters

The aquatic plant Pistia stratiotes L. is environmentally hazardous and requires effective methods for its utilization. The harmfulness of these plants is determined by their excessive growth in water bodies and degradation of local aquatic ecosystems. Mechanical removal of these plants is widespread but requires fairly resource-intensive technology. However, these aquatic plants are polymer-containing substrates and have a great potential for conversion into bioenergy. The aim of the work was to determine the main patterns of Pistia stratiotes L. degradation via granular microbial preparation (GMP) to obtain biomethane gas while simultaneously detoxifying toxic copper compounds. The composition of the gas phase was determined via gas chromatography. The pH and redox potential parameters were determined potentiometrically, and Cu(II) concentration photocolorimetrically. Applying the preparation, high efficiency of biomethane fermentation of aquatic plants and Cu(II) detoxification were achieved. Biomethane yield reached 68.0 ± 11.1 L/kg VS of Pistia stratiotes L. biomass. The plants’ weight was decreased by 9 times. The Cu(II) was completely removed after 3 and 10 days of fermentation from initial concentrations of 100 ppm and 200 ppm, respectively. The result confirms the possibility of using the GMP to obtain biomethane from environmentally hazardous substrates and detoxify copper-contaminated fluids.

Four aquatic plants were tested for the occurrence of unusual polyamines by high performance liquid chromatography and gas chromatography. The whole plants ubiquitously contained norspermidine, homospermidine, norspermine, and thermospermine in addition to usual polyamines such as diaminopropane, putrescine, spermidine, and spermine. Pistia stratiotes L. and Potamogeton distinctus A. Bennett contained aminopropylhomospermidine. Caldopentamine was detected in the former plant. Homospermine was found in Ranuculus aquatilis L. Two tertiary branched tetraamines, N4-aminopropylnorspermidine and N4-aminopropylspermidine, were detected in Potamogeton distinctus and Sagittaria trifolia L.Key words: aquatic plant, polyamine, tertiary branched tetraamine.

The use of phytoremediation technology to remove heavy metal ions from aquatic environments or reduce their toxicity offers the possibility of restoring the ecological environment of polluted water bodies. Based on available literature on heavy metal absorption by aquatic plants, we conducted a meta-analysis to study the absorptive capacities of different plants as well as the factors that influence their Hg-absorption performance. Seventeen plant families, including Araceae, Haloragaceae, Hydrocharitaceae, and Poaceae, have a strong Hg-absorption capacity. The root systems of aquatic plants belonging to these families are primarily responsible for this remediation function, and only a limited proportion of Hg+ that enters a plant via the root system is transferred to other plant organs. Additionally, the diversity of plant life habits (e.g., floating, submerged, and emergent) and the water pH significantly influence the ability of plants to absorb Hg. It is expected that this study will provide a reference for the cultivation of aquatic plants for restoring the ecological environment of Hg-polluted water bodies.

Heavy metals and organic pollutants are ubiquitous environmental pollutants affecting the quality of soil, water and air. Over the past 5 decades, many strategies have been developed for the remediation of polluted water.  Use of aquatic plants to extract, sequester and/or detoxify pollutants and is a new and powerful technique for environmental clean up. Plants are ideal agents for soil and water remediation because of their unique genetic, biochemical and physiological properties.  The aim of this work is to evaluate the potential of free floating duck weed Spirodela polyrhiza to remove heavy metals from waste water and the biochemical effect of heavy metals on Spirodela polyrhiza. Approximately 93% of total heavy metal induced – toxicity appears resulting in the reduced activities of nitrate reductase, total chlorophyll and protein content of the plant. The results recommended the use of Spirodela polyrhiza to ameliorate the wastewater contaminated with heavy metals.

Bali Botanic Garden (BBG) aspires to conduct conservation and research of eastern Indonesian plant species, including the aquatic plant species. These were important as aquatic plant species could be ecologically threatened, beneficial or even dangerous. As scientific data of BBG aquatic plant species collection was limited, we proposed this study to provide researchers and garden managers with data to conduct research, collection and maintenance of the garden aquatic plant collection. The study was carried out by sourcing list of BBG collected plant species data for its aquatic plant species. Literatures study was then carried out to gain information regarding the plant species’ heavy metal phytoremediation, conservation and invasiveness status while data analysis was conducted descriptively. The study result showed that 38 collection numbers of aquatic plant species collected in BGG were placed in five sites within the garden with 94% of all the aquatic plants collection came from Lesser Sunda Islands. Eleven aquatic plants species were listed as Least Concern by IUCN Red List. Fourteen species of collected aquatic plants were proved to possessed phytoremediation potential toward numerous heavy metal pollutants, while six species were listed as an invasive alien plant species in Indonesia. All of the provided data should be enabled the botanic garden stakeholders to come up with ideas in the research and maintenance effort of BBG aquatic plant collection.

Nowadays, undisputable environmental pollution requests endeavors to treat wastewater, particularly containing heavy metal, where wastewater treatment technologies are improving hastily. Hydroxyapatite with micro-porous structure and the large surface area turns into an intense research topic as of its high adsorption capacity. Environmentally friendly Hydroxyapatite powder with the large specific surface is a promising cost-effective precipitation method, for the removal of heavy metals (Al, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, and Zn) from wastewater. Different studies have revealed the efficient removal of all metals using hydroxyapatite or by modified HA using zeolite or chitosan. The increase of Ca2+ ions content in the treated water suggests an ion exchange mechanism

Catfish (Clarias gariepinus) was cultured with an aquatic plant, water hyacinth/eceng gondok  (Eichornia crassipes), kangkung air (Ipomea aquatica) or kapu-kapu (Pistia stratiotes) in concrete ponds, for 3 months. Catfish cultured without aquatic plant was used as a control. The experiment was carried out to evaluate the survival rate as well as the growth of fish and aquatic plants.The survival rates of catfish cultured with I. aquatica, E. crassipes, and P. stratiotes were 76, 87, and 98%, respectively. In addition the survival rate of catfish cultured without any aquatic plant was 93%. The weight gain of catfish was 14,1-16,2 kg per pond. Whereas, the total weight gains of aquatic plant were 37,0,  27,7 and 7,7 kg per pond for E. crassipes, P. stratiotes, and I. aquatica,. Respectively. Dissolved oxygen, and the concentrations of NH3, NH4+ and PO43- in water with aquatic plants were higher than that of in water without aquatic plant. However, the concentration of CO2 was higher in water with aquatic plant.
