This study assessed heavy metal (Cu, Ni, Pb, Zn and Cd) and radionuclide (²²⁶Ra, ²³²Th and ⁴⁰K) pollution and associated risks in the Likuyu River system, Tanzania. Surface water and sediments were collected from five sites along a 22.7 km river stretch, while soils and leafy vegetables were sampled from adjacent farms...
Less attention has been paid to soils with potentially toxic elements (PTEs) below agricultural land risk screening values, even though they continue to accumulate these elements. In this study, four typical areas in Ningxia were selected to determine the concentrations of cadmium (Cd) and arsenic (As) in 176 samples c...

Rapid industrial growth in Export Processing Zones (EPZs) has intensified concerns regarding trace element accumulation in soils and its environmental consequences. This study quantified twelve trace elements in soils from the Mirsarai Export Processing Zone using Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) t...

Naturally mineralized regions exhibit elevated geochemical backgrounds of soil potentially toxic elements (PTEs). However, the use of uniform geochemical baseline values (GBVs) frequently leads to misclassification between natural enrichment and anthropogenic contamination, hindering accurate source identification and...

To characterize heavy metal accumulation, potential sources, and source-specific ecological risks in farmland soils of the Ningxia Yellow River Irrigation Area, 537 topsoil samples were analyzed for As, Hg, Cd, Pb, and Cr. positive matrix factorization (PMF) was coupled with the potential ecological risk index to quant...

Soil cadmium (Cd) pollution is a persistent concern for soil quality, crop production, and food safety. Despite global concerns, spatial predictions of topsoil Cd remain challenging due to limitations in model accuracy, covariate representation, and nonlinearity handling. This study addresses these gaps by integrating...
