Common Treatment Train for Inorganics
A treatment train is the combination of different treatment technologies. A system diagram of a common treatment train for inorganics is illustrated below. Metal contaminated soil is treated using the combination of electrokinetics and phytoremediation. Electrokinetics is used to remove metals from deep soil and ground water. A low density direct current is applied to mobilize charged species, ...

Innovative approach to contaminated soil phytoremediation: Heavy metal phytoextraction using energy crops
Heavy metal accumulation potential in the biomass and different plant parts of the selected species of energy crops cultivated on contaminated soil was evaluated. Phytoextraction potential, biomass yield and qualitative parameters of bioenergy plants grown on heavy metal contaminated soil has been measured. Finally heavy metal influence on biomass utilization possibilities, energy recovery and ...

Effects of single and combined heavy metals and their chelators on aphid performance and preferences
When present at elevated levels in the environment, heavy metals are toxic for most organisms. However, so‐called hyperaccumulator plants tolerate heavy metals and use chelators for their internal long‐distance transport. Thus, phloem‐sucking insects may come in contact with the chelated metals. In this study, the effects of individual and combined heavy metals, zinc and cadmium, as well as of ...

Cadmium and zinc in polluted mining soils and uptake by plants (El Losar mine, Spain)
Total cadmium (Cd) and zinc (Zn) contents in soils around mine spoils ranged from 1.91?80 and 98?9200 mg/kg with an arithmetic mean of 28 and 4079 mg/kg, respectively. These amounts are much higher than the background levels. Higher concentrations of the labile form of Cd (20.7%) and moderate levels for Zn (7.6%) indicate a high environmental threat by these toxic elements. Cadmium contents in ...

Metals Stabilization Using Geochemical Fixation
Introduction To Chemical Fixation There are several approaches to treatment of chromium and other toxic metals such as lead arsenic, and cadmium in soil and groundwater, including isolation, immobilization, toxicity reduction, physical separation, and extraction (U.S. EPA. 2002). Brief Overview Of Metals Remediation Methods: Conventional Methods: Conventional approaches to ex-situ remediation ...

The dose‐dependet influence of zinc and cadmium contamination of soil on their uptake and glucosinolate content in white cabbage (Brassica oleracea var. Capitata F. alba)
The relationship between the ability to accumulate heavy metals (represented by Cd and Zn) and to synthesize bioactive compounds (represented by glucosinolates[GLS]) was investigated in two cabbage cultivars. Plants were grown in the greenhouse of a phytotron under controlled conditions in soils spiked with two different Zn or Cd concentrations. The measurements of Cd and Zn contents in soil ...
