Source apportionment and source-oriented health risk assessment of heavy metal(loid)s in soils of Zibo City, a typical industrial City in China: insights from APCS-MLR and Monte Carlo simulation

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...

Distribution, Source Identification, and Health Risk Assessment of Heavy Metals in Surface and Groundwater Resources of the Sirhind Canal Region, Punjab, India

Water pollution with heavy metals is an important environmental and public health problem, especially in areas that rely heavily on surface water and groundwater for drinking and farming. In the present study, surface water and ground water resources of the Sirhind Canal region of Punjab, India, were studied for the di...

Application of Pollution Load Index (PLI) and Geo-Information Techniques for Evaluating Heavy Metal Distribution in Soils of the Toro Mining District, Nigeria

This study investigates the geochemical characteristics and spatial distribution of heavy metals in soils within the Toro mining district, Bauchi State, Nigeria, to evaluate the environmental impact of prolonged artisanal tin mining. A total of ten (10) composite soil samples were collected from depths of 10–15 cm acro...

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

Pollution Levels, Ecological Risks, and Potential Sources of Toxic Elements in Farmland Soils of the Ibinur Lake Basin, China

Potentially toxic elements (PTEs) are one of the most concerning pollutant types in the surface environment. In this study, a total of 115 farmland soils from the 0–20 cm layer were collected from the Ibinur Lake Basin (ILB) in northwest China to investigate the concentration characteristics, pollution status, potentia...

Contamination Characteristics and Human Health Risks of Heavy Metals in Brownfield Soil from a Decommissioned Electroplating Factory, Shandong Province, China

The relocation and closure of electroplating industries have generated numerous contaminated brownfields, many of which are located in areas with potential for residential and commercial redevelopment. However, information regarding the distribution characteristics, migration, and health risks of heavy metals at decomm...
