Health Risk Assessment of Aluminum and Chromium(VI) Exposure in Groundwater Near Landfills

The degradation of groundwater quality near landfill sites due to potential pollutant exposure requires quantitative evaluation to determine actual health risks to surrounding communities. This study aimed to analyze aluminum and chromium(VI) concentrations and characterize environmental health risk associated with gro...

Exceedance Probability and Toxicity-Value Sensitivity in Health-Risk Assessment of a Pb–Zn Slag Reprocessing Site Under the 2025 IRIS Arsenic Values

Screening-level risk assessments report single-point estimates of carcinogenic risk (CR) and hazard index (HI), conveying neither the probability of exceedance nor its sensitivity to revised toxicity values. We examined both at an active lead–zinc slag reprocessing site in Shymkent, Kazakhstan, by reanalysing a publish...

Source-specific health risk assessment of potentially toxic elements in Wular Lake sediments, Kashmir Himalaya: a Monte Carlo simulation approach coupled with an APCS-MLR receptor model.

Wular Lake, a Ramsar wetland in the Kashmir Himalaya and one of South Asia's largest freshwater lakes, is under growing anthropogenic pressure. This study assessed six potentially toxic elements (PTEs: Cr, Ni, Cu, Zn, Cd, and Pb) in 22 surface-sediment samples using contamination indices, ecological and probabilistic (...

Assessment of heavy metals and radionuclides pollution in an agro-mining river system: implications for environmental and human health

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...

Radiological and Chemical Safety Assessment of Drinking Water from Treatment Plants and Rivers in Kut City, Iraq

Climate change and increasing anthropogenic activities, particularly wastewater discharge into rivers, have raised pollution levels in the water sources of Kut City, necessitating an assessment of the radiological and chemical safety of drinking water at the city's treatment plants. Thirteen water samples were collecte...

Potentially Toxic Elements in Agricultural Soils of an Arid Region: Deterministic and Probabilistic Assessment of Direct Non-Dietary Exposure and Ingestion-Based Human Health Risk

Direct contact with soil and dust may expose people to potentially toxic elements (PTEs) in cultivated soils. We analyzed As, Co, Cr, Cu, Mn, Ni, Pb, V, and Zn in 35 agricultural soil samples from Al Ghat, central Saudi Arabia, using contamination indices alongside deterministic and probabilistic exposure assessments....
