Soil phytoextraction is based on the ability of plants to extract contaminants from the soil. For less bioavailable metals, such as Pb, a chelator is added to the soil to mobilize the metal. The effect can be significant and in certain species, heavy metal accumulation can rapidly increase 10-fold. Accumulation of high levels of toxic metals may result in irreversible damage to the plant. Monit...

Phytoremediation is one of the cost-effective and environmental friendly technologies used to remove contaminants from contaminated soils, which has been intensively studied during the last decade. Presently, few economical and effective remediation methods are available for the remediation of Pb contaminated sites. This study was conducted to assess the potential of 19 plants growing on contam...

Contamination of heavy metals represents one of the most pressing threats to water and soil resources as well as human health. Phytoremediation can be potentially used to remediate metalcontaminated sites. A major step towards the development of phytoremediation of heavy metal impacted soils is the discovery of the heavy metal hyperaccumulation in plants. In this study, the several established ...

This paper aimed to evaluate the ecological risk posed by the accumulation of heavy metals in the salt-affected soils of the habitat covered by the EU Natura 2000 program in relation to the activity of soil redox enzymes. The research was carried out in the halophyte reserve in Ciechocinek (north-central Poland) which is a very specific habitat as it undergoes a long-term human impact related t...

The phytoremediation of metal-contaminated soils offers a low-cost method for soil remediation and some extracted metals may be recycled for value. Both the phytoextraction of metals and the phytovolatilization of Se or Hg by plants offer great promise for commercial development. Natural metal hyperaccumulator phenotype is much more important than high-yield ability when using plants to remove ...

ABSRACT A study was carried out to investigate the potential of Corn (Zea mays) for phytoremediation of soil contaminated with Cadmium and Lead. Soil samplings of 0-20 cm depth were taken from the Chaharmahal Bakhtiari province in the western of Iran. Corn plantlets were planted in pots containing 3 kg of these soils. The experiment consisted of 9 treatments including soil without cadmium and L...

Phytoremediation is an efficient approach that uses plants to remediate the polluted environments.The aim of this research was to evaluate phytoremediation ability of Artemisia aucheriin the contaminated soil to Cadmium, Lead, Zinc and Nickel. A greenhouse experiment was performed to investigate the effect of Municipal Solid Waste Compost (MSWC) on phytoremediation efficiency of A....

Human activities like mining, transport, agriculture, industrial waste disposal and military actions release inorganic pollutants in high concentrations that are toxic to natural ecosystems. Heavy metal pollution causes potential ecological risk. Heavy metals like Cadmium (Cd), Lead (Pb) and Chromium (Cr) when present in high concentrations in soil exert potential toxic effects on overall growt...
