The leaching of Cu, In, Zn, and Pb from a hydrometallurgical residue was significantly affected by the temperature; however, for Pb, it contributed to only 4.5% of its …
This study evaluated the effect of biochar and compost on physiochemical properties, heavy metal content, microbial biomass, enzyme activities, and plant growth in Pb–Zn mine tailings. In this study, a pot experiment was conducted to evaluate the effects of biochar, compost, and their combination on the availability of heavy metals, physicochemical features, …
The lead (Pb) is one of the most common heavy metal contaminants in soils. Plants are exceedingly harmful to it (Zeng et al., 2007).Pb has no biological purpose in plants, although it can create morphological, physiological, and biochemical problems (Zeng et al., 2007, Kumar et al., 2017).A soil lead hazard is defined by the Environmental Protection Agency (EPA) as bare …
In this study, we investigated the concentrations and enrichment coefficient of Pb, Cd, Cu and Zn of 20 samples of 17 plant species in Lanping lead–zinc mine with the objective to (1) get better knowledge of the accumulating capacity of 20 samples of 17 plant species to Pb, Cd, Cu and Zn in such a environment condition, and (2) choose ...
The capability of native plant species grown in polluted post-mining soils to accumulate metals was evaluated in view of their possible suitability for phytoremediation. ...

The Rodalquilar mining district (Almería, SE Spain) is an abandoned mining area in which gold and other metal (Pb–Zn–Cu–Ag–Au) bearing minerals were exploited, mainly in the form of sulphides or native elements. Rodalquilar was exploited for different ores (Pb, Zn, Cu, Mn, Au) at different times (Hernandez 2005). The main ore mined in ...
