Metal contamination Metal contamination of soil represents a potential environmental hazard in terms of toxicity to animals and inhibition of microbial processes (Babich and Stotsky 1985; Bayat and Sari 2010). According to an USEPA survey of 395 remedial action sites, it was found that heavy metals .
The Use of Plants for the Removal of Toxic Metals from Contaminated Soil ... soils requires the removal of toxic metals. Recently, phytoextraction, the use of plants to extract ... contaminated with heavy metals, and heavy metals mixed with organic compounds are shown in Table 2.
Soil contamination causes a negative impact to not only humans but also the microorganisms in the soil. It is well known that heavy metal contamination leads to a decrease in bacteria and actinomycetes and an increase in filamentous fungus in the soil. In addition, the acidification of soil has become a .
Heavy metal contamination of soil may pose risks and hazards to humans and the ecosystem through: direct ingestion or contact with contaminated soil, the food chain (soilplanthuman or soilplantanimalhuman), drinking of contaminated ground water, reduction in food quality (safety and marketability) via phytotoxicity, reduction in land ...

• Identify potential source locations of heavy metal soil contamination, such as areas of former spills and leaks. • Provide a labeled, surveyed, and scaled plot plan or diagram showing current, and any previous locations of structures used for heavy metal plating, chemical and hazardous waste storage, treatment and disposal at the facility.
Phytoremediation is a green emerging technology used to remove pollutants from environment components. Mechanisms used to remediate soils contaminated by heavy metal are: phytoextraction, phytostabilisation, phytovolatilization and rhizofiltration. The two first mechanisms are the most reliable. Many factors influence the choice of the suitable phytoremediation strategy for soil decontamination.
Oct 19, 1999· Method for treating soil contaminated with heavy metals . United States Patent . Abstract: A method for treating heavy metal contaminated soils, particularly those containing hexavalent chromium, which includes a first soil washing at pH 912 with an anionic synthetic organic flocculant followed by a liquidsolid phase separation such ...
Removal of copper and nickel by the addition of the biodegradable chelating agent, chitosan and ethylenediamine tetraacetic acid (EDTA), was investigated, alongside the reaction of a reference compound sodium citrate for comparison. The artificialcontaminated soils were used in this study. The experiments showed that the extraction ability for copper and nickel from the contaminated soil ...
Finally, the coping mechanisms used by plants growing under metal contamination will be discussed. 2. Remediation of heavy metal contaminated sites Soils that are heavily contaminated by metals may pose health risks to humans and to other living organisms in an ecosystem. Current techniques used to remediate metal contaminated
accumulators of heavy metals into their edible tissues concentration of heavy metals in a plant to the [18]. Metals transfer from soil to plants is the main way for concentration of heavy metals in soil. The transfer factors humans' exposure to the contamination of the soil. (TF) for each heavy metal were computed as described by
The problem of heavy metal contamination in the environment is widespread. Taken up by plants, heavy metals may enter the food chain, and therefore, humans can also be exposed to them (Intawongse and Dean 2006).A recently published WHO/FAO report recommends consumption of minimum of 400 g of fruit and vegetables per day (excluding potatoes and other starchy tubers) for prevention of chronic ...
