Abandoned mine tailings, rich in potentially toxic elements (PTEs), can be redistributed in urban areas through atmospheric resuspension. This process serves as a dynamic geochemical compartment linking legacy contamination to human exposure. This study investigated the occurrence, oral bioaccessibility, ecological significance, and human health risks of PTEs in urban dust from Boquira, a former Pb–Zn mining district in northe...

Phosphogypsum is a soil conditioner used to enhance lime effects in depth and also to decrease aluminum (Al) toxicity to plants. It is a by-product from phosphate mining and can be enriched in some contaminants, such as rare earth elements (REE), uranium (U), and thorium (Th). However, there is a lack of studies evaluating the long-term effects of this practice, particularly in soil depths. To address this gap, this study aime...
