“…The promising strategy of in situ uranium bioremediation is being extensively investigated employing microorganism and plant in the recent 20 years [4][5][6][7][8][9][10]. The processes of adsorption, complexation, reduction, precipitation, mineralization and intracellular accumulation on uranium by organism substantially decreases the concentration of dissolved U(VI) in the uranium contaminated water and sediments [11][12][13][14][15]. Concerning about in situ remediation on the large area and low concentration of uranium contaminated water, the native aquatic plant should been selected depend on the high uranium accumulation and tolerance ability and the advantages of manageable.…”

“…In soil replacement method, the contaminated soil is partly replaced by clean soil so as to minimize the concentration of contaminant in the soil [5]. However, this method is costly and is feasible only in a small area.…”

“…On the contrary, in the thermal desorption method, the contaminated soil is heated so as to volatilize the pollutant in the soil. These volatile metals are collected using vacuum pressure and are thus removed from the soil [5]. However, being laborious and costly, this method finds limited applicability in remediation of soils.…”

Several measures have been devised for remediation of heavy metals from contaminated sites. USEPA [4] classified remediation measures of contaminated soils into two types: in-situ and ex-situ treatment. In in-situ treatment, soil is treated at its original place, AbstractAgricultural soils are receiving tremendous amount of pollutants from the various sources. Heavy metal contamination in agricultural soils may impart functional disorders of soils, retarded plant growth and even harm the health of humans through contamination of food chain. These heavy metals or metalloids do not undergo microbial and chemical degradation and persist in the soil for longer duration. This review emphasizes on the sources of heavy metals in soil and remediation technologies involved in their removal from the soil.

“…With the gradual depletion of fossil energy, nuclear energy has become one effective way to solve the energy crisis and received attention all over the world (Li and Zhang 2012;Carvalho et al 2011;Goulet et al 2011). This has resulted in the increase in the demand for uranium and the scale of uranium mining and processing, which has in turn increased the production of the uranium wastewater.…”

“…Many methods for treating uranium wastewater, such as extraction, ion exchange, reverse osmosis, evaporation, adsorption, and precipitation, have been proposed, but they have been found to have disadvantages such as high cost, process complexity, difficulty of subsequent processing, and potential to produce secondary pollution (Bhalara et al 2014;Li and Zhang 2012). Furthermore, carbonate concentration is a limiting factor for ion exchange, adsorption, precipitation, and softening since it has a significant effect on the speciation of uranium (Katsoyiannis and Zouboulis 2013).…”

Aspergillus niger was inoculated to the roots of five plants, and the Syngonium podophyllum-A. niger combinate system (SPANCS) was found to be the most effective in removing uranium from hydroponic liquid with initial uranium concentration of 5 mg L(-1). Furthermore, the hydroponic experiments on the removal of uranium from the hydroponic liquids with initial uranium concentrations of 0.5, 1.0, and 3.0 mg L(-1) by the SPANCS were conducted, the inhibitory effect of A. niger on the growth of S. podophyllum in the SPANCS was studied, the accumulation characteristics of uranium by S. podophyllum in the SPANCS were analyzed, and the Fourier transform infrared (FT-IR) and extended X-ray absorption fine structure (EXAFS) spectra were measured. The results show that the removal of uranium by the SPANCS from the hydroponic liquids with initial uranium concentrations of 0.5, 1.0, and 3.0 mg L(-1) reached 98.20, 97.90, and 98.50%, respectively, after 37 days of accumulation of uranium; that the uranium concentrations in the hydroponic liquids decreased to 0.009, 0.021, and 0.045 mg L(-1), respectively, which are lower than the stipulated concentration for discharge of 0.050 mg L(-1) by the People's Republic of China; that A. niger helped to generate more groups in the root of S. podophyllum which can improve the complexing capability of S. podophyllum for uranium; and that the uranium accumulated in the root of S. podophyllum was in the form of phosphate uranyl and carboxylic uranyl.
