Selected techniques of soil phytoremediation with the use of hyperaccumulative plants and trees are intended to outline the possibilities of using various hyperaccumulative plants, including trees, in the phytoremediation process of contaminated soil matrix. The potential of plants that belong to the group of hyperaccumulators is huge, especially in the case of pollution of large areas of agricultural, forest and urban soil. They can be used in the process of cleaning contaminated, industrially degraded areas and supplement the physical and physicochemical methods of remediation of contaminated areas.

Biosurfactants have recently gained attention as “green” agents that can be used to enhance the remediation of heavy metals and some organic matter in contaminated soils. The overall objective of this paper was to investigate rhamnolipid, a microbial produced biosurfactant, and its ability to leach uranium present in contaminated soil from an abandoned mine site. Soil samples were collected from two locations in northern Arizona: Cameron (site of open pit mining) and Leupp (control—no mining). The approach taken was to first determine the total uranium content in each soil using a hydrofluoric acid digestion, then comparing the amount of metal removed by rhamnolipid to other chelating agents EDTA and citric acid, and finally determining the amount of soluble metal in the soil matrix using a sequential extraction. Results suggested a complex system for metal removal from soil utilizing rhamnolipid. It was determined that rhamnolipid at a concentration of 150 μM was as effective as EDTA but not as effective as citric acid for the removal of soluble uranium. However, the rhamnolipid was only slightly better at removing uranium from the mining soil compared to a purified water control. Overall, this study demonstrated that rhamnolipid ability to remove uranium from contaminated soil is comparable to EDTA and to a lesser extent citric acid, but, for the soils investigated, it is not significantly better than a simple water wash.

Hydrocarbon contaminants have become a global concern due to their long-term adverse effects on soil ecosystems and human health. Successful implementation of phytoremediation to clean up hydrocarbon contaminants requires the identification of the most effective remediation plant species. Twelve native plant species of the Sudd Wetland in South Sudan were evaluated for their potential application as phytoremediators. The treatments included six total petroleum hydrocarbon (TPH) concentrations of 0, 25, 50, 75, 100 and 125 g/kg soil. The twelve native plant species tested were: Sorghum arundinaceum Desv., Oryza longistaminata A. Chev. & Roehrich, Hyparrhenia rufa Nees, Abelmoschus ficulneus L., Gossypium barbadense L., Nicotiana tabacum L., Sorghum bicolour L. Moench, Eleusine coracana Gaertn., Capsicum frutescens L., Zea mays L., Tithonia diversifolia Hemsl. and Medicago sativa L. Significant differences in phytoremediation rates were observed amongst the treatments with exception of the 125 g/kg soil concentration of hydrocarbon that was lethal to all the plant species. Over 50% TPH reduction in the 75 g/kg soil concentration was observed in contaminated soil phytoremediation in H. rufa, G. barbadense, O. longistaminata, T. diversifolia and S. arundinaceum, making them potential phytoremediators of hydrocarbon-contaminated soil in the Sudd-Wetland of South-Sudan.

Soil contamination is one of the most widespread and serious environmental problems confronting both the industrialized as well as developing nations like India. Different contaminants have different physicochemical properties, which influence the geochemical reactions induced in the soils and may bring about changes in their engineering and environmental behaviour. Several technologies exist for the remediation of contaminated soil and water. In the present study soil washing technique using plain water with surfactants as an enhancer was used to study the remediation of soil contaminated with (i) an organic contaminant (engine lubricant oil) and (ii) an inorganic contaminant (heavy metal). The lubricant engine oil was used at different percentages (by dry weight of the soil) to artificially contaminate the soil. It was found that geotechnical properties of the soil underwent large modifications on account of mixing with the lubricant oil. The sorption experiments were conducted with cadmium metal in aqueous medium at different initial concentration of the metal and at varying pH values of the sorbing medium. For the remediation of contaminated soil matrices, a nonionic surfactant was used for the restoration of geotechnical properties of lubricant oil contaminated soil samples, whereas an anionic surfactant was employed to desorb cadmium from the contaminated soil matrix. The surfactant in case of soil contaminated with the lubricant oil was able to restore properties to an extent of 98% vis-à-vis the virgin soil, while up to 54% cadmium was desorbed from the contaminated soil matrix in surfactant aided desorption experiments.

ABSTRAKPenelitian ini bertujuan untuk mengetahui pengaruh pemangkasan akar (underground root pruning/URP) terhadap fitoremediasi tanah yang tercemar merkuri di Kokap Kulon Progo Yogyakarta. Penelitian ini dilaksanakan menggunakan rancangan acak kelompok lengkap dengan tiga ulangan. Faktor pertama adalah URP, yaitu dengan dan tanpa URP. Faktor kedua ialah takaran Jamur Mikoriza Arbuskula (JMA), meliputi 0; 50; 100, dan 150 g/pot. Hasil penelitian telah membuktikan bahwa pemangkasan akar serta inokulasi JMA ke dalam tanah sisa olahan penambangan emas telah berhasil memacu proses fitoremediasi melalui perluasan rizosfer. Serapan merkuri oleh tanaman Jati yang menjalani pemangkasan akar serta inokulasi JMA sebanyak 100% paling tinggi dibanding perlakuan lain maupun kontrol. Pada perlakuan ini, efisiensi penurunan merkuri di dalam tanah oleh tanaman jati sebesar 88,61%, sedangkan kontrol hanya mencapai 64,11%. ABSTRACTThis study aims to determine the effect of underground root pruning (URP) of the mercury-contaminated soil phytoremediation in Kokap Kulon Progo, Yogyakarta. This study was conducted using complete randomized block design with three replications. The first factor is the URP, that divided as with and without URP (root pruning). The second factor is the dose of JMA, are 0; 50; 100, and 150 g/pot. Results of studies have proven that the root pruning and inoculation of JMA into the residual gold mining soil has successfully accelerated the process of phytoremediation through the expansion of the rhizosphere. Mercury uptake by Tectona grandis, Linn F that is with root pruning and 100% JMA inoculation are highest other treatment and control. In this treatment, the removal efficiency of mercury in the soil by plants amounted to 88.61% identity, meanwhile control only reached 64.11%.

One of the possibilities of removing heavy metals (HMs) from soil is the use of phytoremediation techniques supported with biosolids, which also allow for their disposal. Therefore, the objective of the research was the determination of the sewage sludge suitability after its application to urban soil in order to increase the phytoremediation efficiency of contaminated soil. A field experiment was established on lawns in Białystok (Poland) in two locations with different traffic. The research plots were fertilized with sludge in doses of 14.5 t DM/ha and 29 t DM/ha. A mixture of lawn grasses was sown on the prepared plots. During two years of experiment soil/plant samples were collected, and pH, organic matter, dehydrogenase and catalase activity (soil), the total content of Cd, Cr, Cu, Mo, Ni, Pb, Zn, and Hg (soil/plant), and their fractions (soil) were determined. The HMs in soil were present mainly in residual and reducible fractions. Zn had the highest share in acid-soluble fractions (17–45%). The efficiency of urban soil phytoremediation was determined by the calculation of bioconcentration (BCF) and translocation (TF) factors. The highest values for BCF and TF were obtained for Mo (1.97 and 1.99, respectively). In the presented study, sludge amendment caused an immobilization of heavy metals.
