Nitrogen fertilization could improve the efficiency of Cd phytoextraction in contaminated soil and thus shorten the remediation time. However, limited information is available on the effect of N form on Cd phytoextraction and associated mechanisms in plants. This study examined the effect of N form on Cd accumulation, translocation, and speciation in Carpobrotus rossii and Solanum nigrum Plants...

Soil and air pollution are main problems posing a serious threat to human health. Traditional physical chemical soil remediation methods affect the ecosystem rather costly. Since purpose of is not only remove pollutants but also restore health, method phytoremediation becoming extremely relevant. Phytoremediation an environmentally friendly natural process removing from environment. Cleaning up...

Arsenic (As) is a pollutant of major concern throughout the world, and causes serious environmental problems in many areas including, for example, West Bengal, Bangladesh, and Vietnam. Phytoremediation is potentially a cost-effective and environmentally benign method of extracting pollutants from soils for which there have been significant recent advances for As. In particular, the discovery of...

Soils contaminated with radionuclides, particularly 137Cs and 90Sr, pose a long-term radiation hazard to human health through exposure via the foodchain and other pathways. Remediation of radionuclide-contaminated soils has become increasingly important. Removal of the contaminated surface soil (often up to 40 cm) or immobilization of radionuclides in soils by applying mineral and chemical amen...

Arsenic contamination in soils occurs widely in a range of ecosystems resulting from geological origins and anthropogenic activities. On average, arsenic concentration ranges from 5 to 10 mg kg−1 in uncontaminated soils and above 10 mg kg−1 in contaminated soils (Hossain, 2006). Increased buildup of arsenic in irrigated soils has been widely recognized in South and South-east Asia (Brammer and ...

The technology of phytoremediation is cost effective and ecologically friendly in which plant utilizes its natural abilities to restore environment. In nature there are a number of plants existing with innate mechanisms for removing heavy metals from soil, air and water as a survival strategy.  Among several subsets of phytoremediation, the widely studied strategies are (a) phytoextraction (b) ...

pot experiment was carried out to investigate the effects of ethylenediaminetetraacetic acid (edta) on some morphological characteristics of thlaspi caerulescens l., and also on the accumulation of lead (pb) and zinc (zn) in roots and shoots of t. caerulescens l.. experiments were then set up in three treated pots with doses of 3, 6 and 9 mmol kg-1 of edta and control pots (c: uncontaminated so...

In European Union countries up to 80% of sewage sludge is used in agriculture and forestry, whereas in Poland only 11% is used as fertilizer. The principal environmental concern is the inevitable presence of heavy metals when using sewage sludge as fertilizer. The main objective of this study is to assess the effectiveness of the phytoextraction process in removing heavy metals from sludges. A ...

A phytoextraction treatment enhanced by electric field to decontaminate a heavily Pb polluted soil has been tested in a greenhouse-scale experiment. Brassica juncea was selected as Pb-hyperaccumulator plant. The influence of the application of two Electric Potential Difference values (0.6 and 1.1 V cm) and the addition of EDTA (2.5 mmol kg) on biomass production, plant uptake, contaminant leach...

in this research a pot experiment was carried out to investigate the remediation ability of e. camaldulensis dehnh inlead-zinc (pb-zn) contaminated soil. the study also investigated the effects of ethylenediaminetetraacetic acid(edta) and diethylenetrinitrilopentaacetic acid (dtpa) on the phytoremediation efficiency of the plant species, andharvest time as a suitable dose of chelating agents wa...
