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 …
Mining activities have led to heavy metal contamination in most agricultural soils and in food crops 1,2,3,4.Most of the heavy metals (copper (Cu), zinc (Zn), manganese (Mn) etc.) are essential ...
Historical and active mining has adversely affected the geochemistry of the Jiehe River in the Jiaodong Peninsula, which has the largest gold ore reserves in China. Water and sediment samples were collected along the 37.8 km long river during the critical low flow season. Samples were analyzed for their geochemical properties, total concentrations of As, Cr, Pb, …
Specifically, BR can be used to efficiently remove As, Cu, Cd, Pb, and Zn from mine tailings and highly contaminated acidic soil via precipitation due to its high pH [29, [31][32][33]. Most ...
Through greenhouse cultivation and field investigation, the major constraints on plant colonization at Fankou Pb/Zn mine tailings are analysed. The results show that total Pb, Zn, Cu and Cd contents in the tailings are 34300, 36500, 215 and 82.6 mg cntdot kg-1, while their available contents are 1:5, 1963, 0.71 and 8.03 mg cntdot kg-1 respectively.
Heavy metal pollution from mining tailings has become a serious concern in China. Here, we quantitatively evaluated the accumulation status and environmental risk of the tailings impoundments located in a typical Pb-Zn …
The purpose of this study was to investigate the possibility of effects of humic acid on the fate and mobility of seven heavy metals (Co, Cr, Cu, Mn, Ni, Pb, and Zn) in gold mine tailings. Ten samples were taken from the tailing storage facilities of the Chatree (Akara) Gold Mine in the Phichit province, Thailand. The heavy metal fractionation in the samples was …
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 …
Semantic Scholar extracted view of "Chronic toxicity, bioavailability and bioaccumulation of Zn, Cu and Pb in Lactuca sativa exposed to waste from an abandoned gold mine." by María …
The imbalance between raw materials of high economic importance and their supply has increased the search for new approaches to obtain valuable elements from mining tailings. In this study, the extraction of copper, zinc, and lead from sulfidic tailing in sulfate–chloride media was investigated. A 33 Box–Behnken design was applied to evaluate …
