From environment to human: systematic assessment of heavy metal contamination and exposure in a typical karst agricultural area

Heavy metal contamination, source apportionment and health risk in soil-crop systems of high-geochemical-background Pb-Zn mining area

Summary Mining and smelting, combined with high-geochemical-backgrounds, cause heavy metal accumulation in soil-crop systems, endangering food-chain health. Topsoil (0–20 cm) and three local crops were sampled from Yunnan’s Huize lead-zinc mining area. Pb, Zn, Cu, Cd contamination, spatial patterns, source contribution...

Integrated risk assessment of heavy metal and microbial exposure in coastal agricultural systems

Environmental contamination in coastal agricultural systems frequently involves the simultaneous occurrence of chemical pollutants and microbiological hazards, creating complex risks for ecosystems, livestock, food safety, and human health. The present study provides an integrated assessment of heavy metal contaminatio...

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

Heavy Metal Contamination and Human Health Risk Assessment of Farmland Soils in Ndele, an Oil-Producing Community in the Niger Delta, Nigeria

Agricultural soils in oil-producing regions of the Niger Delta may receive persistent trace-metal inputs from petroleum-related activities and other anthropogenic sources, creating potential implications for soil quality, crop production and human exposure. This study assessed cadmium (Cd), lead (Pb) and arsenic (As...

Heavy metal contamination in soil and vegetables: a health risk assessment from urban areas of Sylhet, Bangladesh

Environmental and Human Health Risk Assessment of Heavy Metals in Soils from Automobile Mechanic Villages in Enugu State, Nigeria

Automobile mechanic activities can introduce potentially toxic metals into surrounding soils through the disposal of spent engine oil, metallic scraps, batteries and other vehicle-related wastes. This study assessed heavy metal contamination, ecological risk and potential human-health risks in soils from automobile mec...
