Phytostabilization of Mine Tailings in Arid and Semiarid Environments—An Emerging Remediation Technology
OBJECTIVE Unreclaimed mine tailings sites are a worldwide problem, with thousands of unvegetated, exposed tailings piles presenting a source of contamination for nearby communities. Tailings disposal sites in arid and semiarid environments are especially subject to eolian dispersion and water erosion. Phytostabilization, the use of plants for in situ stabilization of tailings and metal contamin...
متن کاملOptimization of Plant Growth-Promoting Bacteria-Assisted Phytostabilization of Mine Tailings.
Recent studies have indicated that plant growth-promoting bacteria (PGPB) can improve revegetation of arid mine tailings as measured by increased biomass production. The goals of the present study were first to evaluate how mode of application of known PGPB affects plant growth, and second to evaluate the effect of this inoculation on rhizosphere microbial community structure. PGPB application ...
متن کاملPlants from the abandoned Nacozari mine tailings: evaluation of their phytostabilization potential
Phytostabilization is a remediation technology that uses plants for in-situ stabilization of contamination in soils and mine tailings. The objective of this study was to identify native plant species with potential for phytostabilization of the abandoned mine tailings in Nacozari, Sonora in northern Mexico. A flora of 42 species in 16 families of angiosperms was recorded on the tailings site an...
متن کاملReview of Ecological Restoration Technology for Mine Tailings in China
Article history: Received: 11.11.2014. Received in revised form: 4.2.2015. Accepted: 6.2.2015. The disposal of mine tailings is identified as one source of an environmental impact finally resulting in a typically degraded ecosystem. It can easily cause air and water pollution and is a source of man-made mudslides with high-potential socioeconomic-energy impacts. Pollution control and ecological...
متن کاملRevegetation of a Mine Tailings Impoundment Using Municipal Biosolids in a Semi-arid Environment
Five separate test sites were established in 1994 to evaluate the use of municipal sewage sludge as a soil amendment and conditioner (hereafter referred to as biosolids) on the Kennecott Utah Copper Corporations tailings impoundment near Magna, Utah. Each site was divided into 16 test plots to evaluate four replications of the four rates of biosolids addition and incorporation into the taili...
