BACKGROUND, AIM, AND SCOPE Diffusive gradients in thin films (DGT) have been recognized as a suitable tool to assess in situ metal bioavailability in soils. Mine tailings have some singular characteristics such as high heavy-metal concentrations, low pH, or absence of water retention capacity that may compromise the correct application of this technique whose applicability is known to be pH dep...

This study summarizes the main results obtained by the research group from the Instituto de Recursos Naturales y Agrobiología de Sevilla during ten years of study in the mine spill affected area of the Guadiamar river (SW Spain). This work is focussed on 1) trace element changes in soil (total and available concentrations) and plants (native and reforested), and 2) evaluation of the effectivene...

Ahangaran lead-zinc mining area located in the west part of Iran is a mountainous region. In this study, medical plants and soils from 3 different sites in this area were collected in spring 2012. Soil and medical plants were analyzed for heavy metals [lead (Pb), zinc (Zn), cadmium (Cd) and copper (Cu)] concentrations using inductively coupled plasma (ICP) optical emission spectrometer (Varian ...

The mobility and microbially mediated solubilization of Au and As in regolith materials from two Au mines in Australia, i.e., the Peak Hill Gold Mine in semi-arid New South Wales and the Hit or Miss Gold Mine in tropical northern Queensland, was studied using a combination of geochemical and microbiological techniques. Gold is highly mobile in both environments, the mobility of Au increases wit...

The concentrations of As and Zn in 100 georeferenced soils uniformly distributed throughout the area affected by the spill from the Aznalcóllar mine (April 1998) were analysed at three depths (0– 10, 10–30, and 30–50 cm) and on four dates (autumn–winter 1998, 1999, 2001, and 2004). For an estimate of the geochemical background, 30 unaffected soils near the edge of the spill were also analysed a...

Human hair samples from mine workers and Obuasi citizens; various food items; drinking and washing water from Obuasi town; vegetation and soils from the countryside bordering on the goldmine; and geological materials from the mining process were collected and analyzed by volumetric, gravimetric, colorimetric, and neutron activation methods in order to assess the degree of arsenic pollution brou...

Antimony (Sb) is an element with a growing concern due to its toxicity, but also because of criticality. While the impact Sb mining documented in literature from China and Europe, still little data available concerning environmental Vietnam. This paper presents results exploratory study mine waste soil samples Mau Due (North Vietnam). The chemical mineralogical composition was determined as wel...
