Drought in heavy metal polluted arid and semiarid regions severely inhibits the plant growth phytoremediation potential by affecting photosynthesis, antioxidant defense mechanism, other biochemical processes. In present study, we explored role of growth-promoting bacteria (PGPB) on Zea mays efficiency Chromium (Cr) contaminated soils under drought stress assessing tolerance, photosynthetic gas ...
Application of hyperaccumulator-endophyte symbiotic systems is a potential approach to improve phytoremediation efficiency, since some beneficial endophytic bacteria are able to detoxify heavy metals, alter metal solubility in soil, and facilitate plant growth. The objective of this study was to isolate multi-metal resistant and plant beneficial endophytic bacteria and to evaluate their role in...
Phytoremediation is a sustainable process in which green plants are used for the removal or elimination of contaminants in soils. Both organic and inorganic contaminants can be removed or degraded by growing plants by several mechanisms, namely phytoaccumulation, phytostabilization, phytodegradation, rhizofiltration and rhizodegradation. Phytoremediation has several advantages: it can be applie...
Cadmium (Cd) is a metal with high toxicity and solubility in water, which is a serious environmental threat to human health. Phytoremediation is an environment-friendly method and a promising new and cost effective technology that uses plants to clean organic and inorganic contaminated media. This study was conducted to evaluate the potential of Jatropha curcas for remediation of soils contamin...
The objective of this study was to determine the effects of lead (Pb) exposure on bioaccumulation, growth, and tolerance mechanisms in summer savory (Satureja hortensis L.). Plants were subjected to different levels of Pb concentrations including 0 (control), 5, 10, 25, 50 and 100 mg L-1 in growing medium. Pb treatment led to significant increase in root and shoot Pb content. Calculation of BF,...
One of the major problems about the chelant-enhanced phytoextraction is the potential metal leaching associated with chelant application. A glasshouse pot experiment was conducted to investigate phytoextraction efficiency of common reed (Phragmites australis (Cav.) Trin. ex Steudel) for Lead and Chromium and to determine EDTA (ethylenediaminetetraacetic acid) enhancement of the mobility and phy...
Phytoremediation is a technology that uses plants for the remediation of the contaminated soils, sediments, tailings, and groundwaters. In this work, the ability of TrifoliumAlexanderium for the phytoremediation of the tailings soil in the Anjir-Tange coal washing plant was investigated. For this purpose, Trifolium sp. was cultivated in three soils consisting of the tailings dam, an agricultura...
This research was performed to compare Pb and Cd accumulation in root and leaves of pinus brutia. The effects of these elements in different concentrations (0, 200, 500 and 1000) on the amount of proline, soluble sugar of the plant were also investigated. The experiment was done in a factorial design in three replicates. The concentration of Pb and Cd in leaves and root were measured by atomic ...
Toxic substances have a deleterious effect on biological systems if accrued in ecosystems beyond their acceptable limit. A natural ecosystem can become contaminated due to the excessive release of toxic by various anthropogenic and activities, which necessitates rehabilitation environmental contamination. Phytoremediation is an eco-friendly cost-efficient method biotechnological mitigation for ...
Green remediation of severely contaminated soils around mining sites can be achieved using suitable woody plants such as Quercus species, but their phytoremediation potential has not been well evaluated yet. Six which were popular in ecological restoration and landscape application east China, selected for metal polluted soil a pot experiment that lasted 150 d. The results suggested species exh...
