Too Hot, Too Cold, Just Right: Thermal Modulating Capacity of Different Sources of Groundwater Discharge to Salmon‐Bearing Streams

River Research and Applications, EarlyView.
ABSTRACT Groundwater discharge plays a key role in maintaining habitat suitability for cold‐water fish by generating streamflow and modulating temperatures. However, the thermal influence depends on groundwater source depth and how far groundwater travels from the point of discharge to a receiving stream.

Geochemical and Isotopic Composition of Natural Waters in the Central Main Ethiopian Rift: emphasis on the study of source and genesis of fluoride [PDF]

, 2009
In the Main Ethiopian Rift (MER), the supply of drinking water principally relies on groundwater wells, springs (including some hot springs), and rivers, and is characterized by a significant problem of fluoride (F¯) contamination.

Illegal Gold Mining in the Brazilian Amazon: Environmental Degradation in Yanomami Indigenous Lands, and Regulatory Failures

Sustainable Development, EarlyView.
ABSTRACT Illegal gold mining has emerged as a major sustainability threat in the Amazon, eroding Indigenous rights, forest integrity, and climate mitigation efforts. This study examines how international market incentives relate to the expansion of illegal mining and associated deforestation within the Yanomami Indigenous Territory (YIT) from 2008 to ...

Assessment of Metal Contamination and Human Health Risk in the Buffalo River Estuary, Eastern Cape, South Africa

Environmental Toxicology, EarlyView.
ABSTRACT Metal contamination in estuarine environments poses environmental and public health concerns, particularly where surface waters support domestic and subsistence uses. This study assessed the seasonal distribution, controlling mechanisms, and non‐carcinogenic health risks of selected metals (Mg, Al, Ba, Fe, Mn, and Zn) in the Buffalo River ...

Bioaccessibility of Metal(loid)s From Anthropogenic Contamination in Dry Riverbed Sediments in the Cartagena–La Unión Mining District (Murcia, SE Spain): Implications for Human Health Risk Assessment

Environmental Toxicology, EarlyView.
ABSTRACT This study assessed the contamination levels, bioaccessibility, and potential health risks of As, Cd, Cu, Pb, and Zn in sediments from three dry riverbeds (El Beal‐EB, Las Matildes‐LM, and Ponce‐PN) impacted by historical mining activities in the Cartagena‐La Unión Mining District.

Integrated Alpha–Gamma Radiation Exposure From Natural Radionuclides in Cement and Gypsum Production: Implications for Occupational Lung Cancer Risk

Environmental Toxicology, EarlyView.
ABSTRACT Natural radionuclides in cement and gypsum production materials pose significant risks of occupational radiation exposure that are not well documented in Iraqi Kurdistan. This study quantifies alpha and gamma radiation levels from naturally occurring radioactive materials, specifically 222Rn, 238U, 232Th, and 40K, in cement and gypsum samples ...

Regional Prediction of Soil Nutrient Availability and Management Using Portable X‐Ray Fluorescence Spectrometry

X-Ray Spectrometry, EarlyView.
ABSTRACT Portable x‐ray fluorescence (pXRF) spectroscopy has emerged as a rapid and cost‐effective technique for soil elemental analysis; however, its application for predicting available nutrients and supporting agronomic decision making remains insufficiently evaluated under field conditions.
