Mining areas are highly susceptible to environmental contamination due to the accumulation of potentially toxic elements (PTEs), necessitating regular monitoring to assess environmental risks. In this study, soil samples were collected from two depths (0-15 cm and 15-30 cm) at 74 stations, along with deep waste samples (0-12 m) from three adjacent tailings ponds in the Mazarrón mining area, Spain. Soil/waste physicochemical properties and the Cd, Cu, Zn, and Pb concentrations of total, water-soluble, and bioavailable fractions were analyzed.

The key objectives of this study were: (i) to investigate the feasibility of using pine needles as a bioindicator and biomagnetic indicator for estimating the concentration of selected metals in street dust, and (ii) to predict the contamination level of street dust by selected metals using magnetic susceptibility. Street dust and pine tree needle samples were taken from 60 locations in three adjacent cities in Kerman province (Kerman, Rafsanjan, and Sirjan), southeastern Iran.

The aim of this study was to evaluate the most abundant native plants that could be used as a bio-monitor of metal(loid) concentration in dry riverbeds affected by mining activities. Three plants species and their respective rhizospheric soils were sampled from the El Beal (, 15 samples), La Carrasquilla (, 10 samples), and Ponce (, 12 samples) dry riverbeds from the mining district of Cartegena-La Unión (SE Spain). There is scanty bibliography of the capacity of these species to be used as bio-monitors in the dry riverbeds.
