Toxic metal contamination of soil is a major environmental hazard. Chemical methods for
heavy metal's (HMs) decontamination such as heat treatment, electroremediation, soil …

Selenium (Se), which can be both hazardous and beneficial to plants, animals and humans,
plays a pivotal role in regulating soil-plant-human ecosystem functions. The biogeochemical …

Polluted soil and water impact the quality of food and nutrients of human and animal biota.
Soil and water are mainly polluted by effluent discharges from industries, which are broadly …

The use of plants in environmental remediation has been called “green remediation,”“
phytoremediation,”“botanical bioremediation,”“phytoextraction,” etc. Phytoremediation …

Soils polluted with heavy metals have become common across the globe due to increase in
geologic and anthropogenic activities. Plants growing on these soils show a reduction in …

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 …

▪ Abstract Plants vary considerably in their physiological response to selenium (Se). Some
plant species growing on seleniferous soils are Se tolerant and accumulate very high …

The importance of biodiversity (below and above ground) is increasingly considered for the
cleanup of the metal contaminated and polluted ecosystems. This subject is emerging as a …

Although some heavy metals are essential trace elements, most of them can be toxic to all
forms of life at high concentrations due to formation of complex compounds within the cell …
