“…According to Haque, et al, [29], the decreasing of the EC could be due to saturation, in the transfer of the plant's metal uptake into other plant tissues, of high metal concentrations. This result agrees with the previous discussion.…”

Abstract. Paddy fields in the Rancaekek area, Bandung Regency-Indonesia, has been contaminated by textile wastewater. The area needs to recover back to its normal condition and function. Several compounds were found in the soil, such as Cu, Zn, Pb, Cd, Co, Ni, and Cr. Phytoremediation was selected as a site remediation strategy, which employs plants to remove non-volatile and immiscible soil contents. The objective of the study was to determine the ability of Equisetum debile to absorb Cu from the contaminated soil. Cu measurement was conducted by using the AAS (Atomic Absorption Spectrophotometer) method. The study has shown that Equisetum debile can absorb Cu concentrations of up to 25.3 ppm in 60 days after initial planting. However, the Enrichment Coefficient value (0.392) indicated that Equisetum debile was not efficient as a hyperaccumulator plant.

“…Heavy metal contamination has been one serious problem in the vicinity of abandoned mine sites due to the discharge and dispersion of mine-waste materials into the ecosystem (Jung and Thornton, 1996). These heavy metals have a potential to contaminate soil and water (Haque et al, 2008;Lim et al, 2008).…”

Human activities such as metals mining and milling operations provide one of the most important sources of contamination in the environment. Abandoned mines can be an important source of toxic elements. The threat of heavy metal pollution posed by mine soils generally concerns more than one metal. The aim of this study was to assess total concentration of six potentially toxic metals (Cd, Cr, Cu, Pb, Zn and Fe) in the soil and plant samples of three dominant willow species (Salix purpurea L., Salix caprea L. and Salix eleagnos Scop.) collected from abandoned mixed sulphide mine dumps (Imperina Valley, North-east Italy). Results demonstrate that metal concentrations in soils are in general above the Italian average limits and they are also significantly (except Cr), as compared with controls (p ≤ 0.05), with averages of 2.12 mg Cd kg −1 , 2267 mg Cu kg −1 , 9552 mg Pb kg −1 , 1243 mg Zn kg −1 and 299,973 mg Fe kg −1 . The phytoremediation ability of selected Salix species for heavy metals was estimated. The results have revealed significant differences among willow species (p ≤ 0.05) regardless of the species selected. The transfer factor and bioaccumulation coefficient of selected metals varied among plant species and from different sites. Some of the investigated species have potential for soil stabilization and extraction of heavy metals. The results indicate that there is an increasing need for further research projects mainly focused on the mechanisms whereby such willows are able to survive in contaminated soils.

“…These parameters represent the capability of the plant to absorb, to transport and to store contaminants in the above-ground part of plant (Haque et al, 2008). It is known that hyperaccumulator plants can 10 -500 times more than non-hyperaccumulator plants (Rotkittikhun et al, 2006).…”

A pilot reed bed study was conducted with the aid of aeration to remove lead (Pb) contaminated water using Scirpus grossus L. f. The plants were grown in sand medium in pilot-scale reed beds, and exposed to water containing Pb in a various concentration (10, 30 and 50 mg/L) with aeration rate of 2 L/min. The samples were taken on day-1, day-14, day-28, day-42, day-70 and day-98. The results showed that Pb concentration in water decreased 74% on day-7, 80% on day-14, 99% on day-28 and reach 100% on day-48 for treatment 10 mg/L. Pb concentration decreased 91% on day-7, 93% on day-14 and then on the day-28 the reduction reached 99% for treatment of 30 mg/L. For Pb treatment of 50 mg/L, the reduction reached 92% on day-7, 96% on day-14, and 99% on day-28. The sand adsorbed Pb up to 7.91×10 -4 mg/kg for 10 mg/L, 1.07×10 -3 mg/kg for 30 mg/L and 2.41×10 -3 mg/kg for 50 mg/L. Pb uptake by plant was 2286 mg/kg on day-98, 4174 mg/L on day-28
