Historical mining districts are long-term sources of environmental contamination, especially where agriculture and grazing occur near mining areas. This study evaluates mercury (Hg) and other potentially toxic elements (PTEs) in soils from Solana de Peñarrubia, within the Almadén mining district (Spain). Thirty-four so...

The spatial distributions of the potential ecological risk index (RI) and the geoaccumulation index (Igeo) in soils of the Zhetysu region (Kazakhstan) were examined. The enrichment factor ranged from 39.4 for cadmium to 21,481 for nickel. There are few non-ferrous metal enterprises and mineral deposits located in the r...

Subsurface contamination in mining-affected paddy soils raises questions about how concentration changes with depth relate to contamination persistence and metal partitioning. We sampled 46 paddy field sites in Guangdong, China, at 0–20, 20–40 and 40–60 cm. Total concentrations of eight elements were measured by induct...

Heavy metal accumulation in island soils is a critical environmental issue because spatially constrained coastal systems receive overlapping inputs from urbanization, tourism-supporting infrastructure, shipping, industry, and agriculture. In this study, 43 surface-soil samples from 42 locations on Zhoushan Island, Chin...
Potentially hazardous element (PHE) contamination threatens agroecosystem sustainability and food security, particularly in irrigated regions. The Yellow River Basin in Northwest China is a critical agricultural zone where intensive irrigation and fertilizer use may accelerate soil contamination.
A total of...

Urban soils act as long-term reservoirs for trace metals, yet how soil physicochemical properties and anthropogenic pressure interact over time remains poorly understood in medium-sized cities of the Global South. This study evaluates the spatiotemporal dynamics and ecological risks of Ba, Cu, Zn, Pb, Cr, Ni, Mo, Co, a...
