Assessment of radiological health effects of radon and toxic heavy metal concentrations in imported coffee samples consumed in Iraqi Kurdistan region, Iraq

Scientific Reports
Radon and toxic heavy metals in food products can create serious issues to consumer health. The levels of specific heavy metals and radon in imported coffee samples that were consumed in the Iraqi Kurdistan region were evaluated in this study.

Carbon Cycle Succession Across a Permafrost Thaw Gradient in Northeastern Alberta as Revealed by δ13C in Dissolved Solids, Gases, and Particulates in Lakes

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 2, February 2026.
Abstract δ13C in particulate organic carbon (POC), dissolved organic carbon (DOC), dissolved inorganic carbon (DIC), carbon dioxide (CO2(g)) and methane (CH4(g)), together with geochemical modeling, were applied to describe carbon cycle evolution in 40 boreal lakes situated across a permafrost thaw gradient in northeastern Alberta, Canada, where ...

Radon Levels of Water Sources in the Southwest Coastal Region of Peninsular Malaysia

Applied Sciences, 2021
Across populations, the dominating source of public exposure to radiation is radon gas. In the present study, we aimed at determining the concentration of radon in water sources from the southwest coastal region of Peninsular Malaysia.

Tropicalization Enhances Mangrove Methane Emissions to the Atmosphere

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract Organic‐rich mangrove soils release CH4, partially offsetting the climate benefits of high organic carbon sequestration. However, the local and global drivers and variability of mangrove CH4 emissions remain poorly understood. Here, we quantify water‐atmosphere CH4 emissions over hourly, daily, and weekly time scales in an Australian mangrove ...

Assessment of Natural Radioactivity and Radon Exhalation in Peruvian Gold Mine Tailings to Produce a Geopolymer Cement

Atmosphere, 2023
Mining generates significant amounts of waste that can represent a source of contamination for areas close to the extraction area, generating a negative impact both on the environment and the health of people. This study aims to evaluate the radiological

Overlooked seasonal groundwater nutrient fluxes rival anthropogenic point sources across a variable land‐use tidal river

Limnology and Oceanography, Volume 70, Issue 12, Page 3815-3831, December 2025.
Abstract Understanding groundwater–surface water connectivity in tidal freshwater zones is essential for managing ecosystems within the riverine–estuarine continuum. Groundwater discharge is a key source of dissolved nutrient loads that can lead to eutrophication, deoxygenation, and other ecosystem imbalances in coastal environments.

Using 222Rn to Determine Groundwater Velocities in a Braidplain Aquifer

Hydrological Processes, Volume 39, Issue 10, October 2025.
This study assesses bank infiltration from a braided river. We find a small change in infiltration velocity for high versus low river flow periods, and a spatial variation of groundwater velocities linked to paleochannels. Consideration of more realistic groundwater flow geometries demonstrates that groundwater residence times based on conventional ...
