Spatio-temporal Variability of Potentially Toxic Elements and Minerals in Indoor and Outdoor Environments of a Semi-arid Metropolis

Soil Characteristics of an Arctic City: Mineralogical and Chemical Composition, Pollution Risks and Toxicity Assessment (Novy Urengoy, Russia)

Urbanization leads to multi-component environmental pollution, so it is especially important to conduct a comprehensive screening of transformations of vulnerable Arctic soils. An assessment of urban soil pollution in Novy Urengoy was conducted, providing a detailed geochemical characterization of the study areas. El...

Spatial distribution and geochemical assessment of arsenic, lead, and zinc in stream sediments from an agricultural region influenced by mining activities in Zacatecas, Mexico

Spatial Distribution of Mercury and Potentially Toxic Elements in Soils from an Agricultural and Grazing Area Affected by Historical Mining

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...

Microplastic and potentially toxic element Co-contamination in semi-arid agricultural and peri-urban soils of Tamansourt (Marrakech Region, Morocco)

Microplastics (MPs) are an emerging soil contaminant, whereas potentially toxic elements (PTEs) are long-recognized persistent pollutants; their co-occurrence and potential interactions in terrestrial ecosystems are of growing concern. In semi-arid regions such as Marrakech (Morocco), where wastewater reuse and plastic...

Heavy metal contamination, risk assessment, and source apportionment of roadside dust in a rapidly urbanizing tropical city: Implications for developing urban environments

ECOLOGICAL AND GEOCHEMICAL CHARACTERISTICS OF SPRINGS IN URBAN AREAS: FROM LOCAL SAMPLING TO RISK ASSESSMENT

Groundwater composition is governed by natural factors such as water runoff that dissolves rocks and acquires organic content from soils. The expansion of urban and industrial areas has significantly altered groundwater formation processes, introducing technogenic salts content (Cl–, SO42–, NO3–, NH4+) comparable to na...
