Extremely High Phosphate Sorption Capacity in Cu-Pb-Zn Mine Tailings
Elevated inorganic phosphate (Pi) concentrations in pore water of amended tailings under direct revegetation may cause toxicity in some native woody species but not native forbs or herb species, all of which are key constituents in target native plant communities for phytostabilizing base metal mine tailings. As a result, Pi sorption capacity has been quantified by a conventional batch procedur...
متن کاملGrowth of Vetiveria zizanioides and Phragmities australis on Pb/Zn and Cu mine tailings amended with manure compost and sewage sludge: a greenhouse study.
The Lechang lead/zinc (Pb/Zn) mine and Dabao Shan copper (Cu) mine are located at the north of Guangdong Province in southern China. The residual tailings were permanently stored in tailings ponds which required revegetation to reduce their impact on the environment. A greenhouse study was conducted to evaluate the feasibility of using Vetiveria zizanioides (vetiver) and Phragmities australis (...
متن کاملPredicting Cu and Zn sorption capacity of biochar from feedstock C/N ratio and pyrolysis temperature
Biochars have been proposed for remediation of metal-contaminated water due to their low cost, high surface area and high sorption capacity for metals. However, there is a lack of understanding over how feedstock material and pyrolysis conditions contribute to the metal sorption capacity of biochar. We produced biochars from 10 different organic materials by pyrolysing at 450 °C and a further 1...
متن کاملCultivation-dependent and cultivation-independent characterization of the microbial community in acid mine drainage associated with acidic Pb/Zn mine tailings at Lechang, Guangdong, China.
Cultivation-based and molecular approaches were used to characterize the phylogenetic composition and structure of the microbial community in an extremely acidic (pH 2.0) acid mine drainage (AMD) associated with Pb/Zn mine tailings that were undergoing vigorous acid generation. Acidophilic bacteria were isolated and enumerated on solid media, and were found to be restricted to isolates related ...
متن کاملMetal (Cu, Zn, Fe, Pb) concentrations in human placentas.
The concentrations of some metals (Cu, Zn, Fe, Pb) in human placentas at term in two populations living in polluted (Krakow, n = 10) and non-polluted (Bieszczady, n = 13) areas were investigated by means of graphite furnace--or flame atomic absorption spectrometry (GF-AAS or F-AAS). The concentrations of Cu, Fe and Pb were higher in Krakow vs. Bieszczady, while Zn concentration was lower, but t...
