“…The use of aquatic plants for heavy metal removal has been extensively reviewed [5] [6] [15]- [17] and widely studied both under laboratory [18]- [20] as well as field conditions [21]- [27]. Insights from all these studies point to the existence of a wide variation in the ability of different plants to accumulate heavy metals and the ability of a particular genera or species to accumulate different amounts of the same heavy metal from different sites.…”

Freshwaters are not only used locally in many developing countries but they are often over exploited for domestic purposes, agriculture and disposal of industrial wastes which result in an overload of excess nutrients, harmful chemicals and heavy metals. Plant species together with sediments and water samples collected from eleven aquatic water bodies in the vicinity of industrial units in Kolkata were studied for their potential to uptake Pb, Cd and Cr under field conditions. Cd and Cr concentrations in the sediments were higher than background values considered to be toxic.Alternanthera philoxeroides and Eichhornia crassipes were the two invasive species present, with the former being more widely distributed. Among native plants, Ipomoea aquatica was the most abundant. Metal uptake in the plants differed among species, tissues and sites. Pb and Cd accumulation in root tissues for all plants in most sites suggested an exclusion strategy for metal tolerance. Since I. aquatica is widely consumed in many parts of SE Asia, its metal content should be checked before use since it was found to efficiently translocate both Pb and Cd from roots to shoots.The potential of A. philoxeroides as a metal excluder needs to be explored further since it translocates less to its shoots as compared to E. crassipes and I. aquatica.

“…Typha spp. has rhizodegradation/phytodegradation mechanism which is useful in reducing organic-aromatic and aliphatic materials, petroleum hydrocarbon contents as well as chlorinated solvent, TNT (trinitrotoluene) and pesticide [4]. The 30-day experiment in our research had proved that T. angustifolia was the species of hydromacrophyte with the highest performance in causing decreases in the leachate quality parameters and it adapted well to FWS type of CW.…”

“…Remediation in vegetated CW system is a complex activity that involves physical processes (sedimentation, filtration and adsorption), chemical processes (coagulation, oxidation-reduction and transformation) and biological processes (decomposition of organic matter into simpler elements by certain bacteria and plant uptake in various specific ways) [10,4]. The impacts of each process rely on the climate, the temperature, the amount of available bacteria, the substrates and the species of the plants [10].…”

The purpose of this research is to analyze the effectiveness of using local hydromacrophytes for performing leachate phytoremediation in constructed wetland (CW) system. It was an ex situ experiment carried out in a glass house by means of free water surface (FWS) CW reactors containing sand and gravel substrates in 3:5 ratio. The reactor was waterlogged by 9 L leachate. The phytoremediation tests were performed in two-factor treatment design involving hydromacrophyte species and hydraulic retention time. Species of local hydromacrophyte used in this research included Alternanthera sessilis, Commelina nudiflora, Paspalum conjugatum, Typha angustifolia and the polyculture of the four species. The improvements in leachate qualities were identified through decreases of physico-chemical parameters.Among the mean values of the percentages indicating the decreases of physico-chemical leachate parameters, the greatest ones were resulted from the treatments using T. angustifolia and A. sessilis on the 30 th day. It has proven in the experiment that these two species of hydromacrophyte perform the most effective process of improving leachate quality.

ABSTRAK ABSTRACTObjectives of this study are to determine the capability of some local hydro-macrophytes as phytoremediation agents for increasing leachate quality from Talangagung Landfill, Kepanjen, Malang. This was an experimental research using completely randomized design with five treatments: control, Ludwigia adscendens, Alternanthera sessilis, Typha angustifolia, and polyculture of three plants. The replication of treatment was five in the same time. Each treatment applied on 25% leachate concentration and was incubated for 30 days. Measurements of leachates quality such as DO, turbidity, nitrates, orthophosphates, and BOD were performed every six days incubation. Data were analyzed by multiple comparison test among incubation day on each treatment. All of the hydro-macrophytes had an ability to increase the quality of leachate, which was reflected by increasing level of DO and decreasing level of turbidity, nitrates, orthophosphates, and BOD. Hydro-macrophytes L. adscendens, T. angustifolia, and polyculture of three plant species had optimum capability to reduce nitrates, orthophosphates, and BOD after 12 days of incubation, while A. sessilis after 18 days of incubation. Highest reduction percentage on nitrates (73.8%) and orthophosphates (68.4%) was found in A. sessilis on day 30 and 24 respectively. While the largest decreasing concentration of BOD (61.4%) was found 30 days after incubation in the treatment of L. adscendens dan T. angustifolia.
