Most of the plants employed to remove metals from contaminated soils are annuals and have a seed-to-seed life cycle of a few months, usually over spring and summer. Consequently, for most of the year, fields are not actively cleaned but are completely bare and subject to erosion by water and wind. The objective of this study was to evaluate the benefits of using Lupinus albus as a winter crop i...

Soil lead (Pb) contamination in Pb paint-contaminated homes is a serious health risk urban areas. Phytoextraction green and sustainable technology for soil remediation, but its efficiency depends on the geochemical partitioning of soil. Following successful laboratory, greenhouse, panel experiments, field study was conducted to demonstrate effectiveness chemically catalyzed phytoextraction mode...

Title of dissertation: EFFICIENCY AND ECOLOGICAL RISKS OF REDUCING SOIL PH DURING THLASPI CAERULESCENS PHYTOEXTRACTION OF CADMIUM AND ZINC Shengchun Wang, Doctor of Philosophy, 2004 Dissertation directed by: Professor Jay Scott Angle Department of Natural Resource Sciences and Landscape Architecture The major aims of this research were to determine whether reducing soil pH can enhance phytoextr...

To improve the efficiency of Ni phytoextraction, metal hyperaccumulator N. goesingensis was subject to treatment with a combination uptake stimulating microorganism and commercially available, IAA- based biostimulating seaweed extract - Kelpak. Additionally, we compared plant growth promoting capabilities two biofertilizers. Treatment Kelpak alone had no significant effect on or accumulation. I...

plants capable of accumulating uncommonly high Zn levels. In 1935, Byers documented the accumulation of Remediation of sites contaminated with toxic metals is particularly selenium in Astragalus spp. One decade later, Minguzzi challenging. Unlike organic compounds, metals cannot be degraded, and the cleanup usually requires their removal. However, this energyand Vergnano (1948) identified plant...

Increased soil pollution with heavy metals due to various human and natural activities has led to a growing need to address environmental contamination. Some remediation technologies have been developed to treat contaminated soil, but a biology-based technology, phytoremediation, is emerging. Phytoremediation includes phytovolatilization, phytostabilization, and phytoextraction using hyperaccum...
