Phytoremediation of heavy metal-contaminated land by trees--a review.
This paper reviews the potential for using trees for the phytoremediation of heavy metal-contaminated land. It considers the following aspects: metal tolerance in trees, heavy metal uptake by trees grown on contaminated substrates, heavy metal compartmentalisation within trees, phytoremediation using trees and the phytoremediation potential of willow (Salix spp.).
متن کاملOptimizing phytoremediation of heavy metal-contaminated soil by exploiting plants' stress adaptation.
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...
متن کاملCadmium Phytoremediation by Arundo donax L. from Contaminated Soil and Water
The potential of Arundo donax L. for phytoextraction of cadmium (Cd) from contaminated soil and water was probed. The plants were grown under greenhouse conditions in pots containing a nutrient solution or soil with increasing doses of Cd (0, 50, 100, 250, 500, 750, and 1000 μg L(-1)) for 21 days. The growth and physiology of plants were evaluated at the end of the experiment. The maximum Cd co...
متن کاملInduced-phytoextraction of heavy metals from contaminated soil irrigated by industrial wastewater with Marvel of Peru (Mirabilis jalapa L.)
The primary objective of this study was to evaluate the effect of ethylene diamine tetraacetic acid (EDTA) and citric acid (CA) on Mirabilis jalapa L. growth and phytoextraction of heavy metals from the multi-metal contaminated soil. The results showed that the application of CA (5 and 8 mmol/kg) and EDTA (5 mmol/kg) increased plant growth, while when the concentration of EDTA was up to 8 mmol/...
متن کاملEffects of Combined Amendments on Growth and Heavy Metal Uptake by Pakchoi (Brassica chinensis L.) Planted in Contaminated Soil
Remediating soils with heavy metals contamination is a significant challenge. This study investigated the co-remediation effect when paired soil amendment mixtures were used to treat soil contaminated by Pb, Cd, and Zn. The three mixed amendments are: 1) micro particle hydroxyapatite (mHAP) and humic acid 2) nano particle hydroxyapatite (nHAP) and humic acid 3) sepiolite and humic acid. Co-reme...
