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 ...

Soil Gas Investigations in Hatay‐Reyhanlı (Türkiye): Implications for Buried Fault Detection and Seismic Hazard Assessment

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 1, January 2026.
Abstract This study presents a soil gas geochemical survey in the Kırcaoğlu and Reyhanlı regions of Hatay Province, southeastern Türkiye, following the 2023 Kahramanmaraş earthquake doublet. The aim was to identify concealed faults and assess seismic hazard through analysis of soil CO2 flux, CO2 and 222Rn concentrations, and carbon and helium isotopic ...

Palaeoenvironmental changes recorded at the Velika Vrbica loess‐palaeosol sequence, Wallachian Basin, during MIS 3–MIS 1

Boreas, Volume 55, Issue 1, Page 134-149, January 2026.
This study presents a detailed investigation of the Velika Vrbica loess‐palaeosol sequence, situated in the Wallachian Basin of northeastern Serbia, with the aim to reconstruct palaeoenvironmental changes spanning Marine Isotope Stages (MIS) 3 to 1. Using optically stimulated luminescence (OSL) dating, low field magnetic susceptibility (χlf), and mass ...

222Rn and 220Rn Levels in Drinking Water, the Related Health Implications, and Influencing Environmental Parameters in the Volcanic Area of Nkongsamba, Cameroon

Applied and Environmental Soil Science, Volume 2026, Issue 1, 2026.
Radon (222Rn) and thoron (220Rn), both naturally occurring radioactive gases, are significant contributors to radiation exposure, posing risks such as lung and stomach cancer. This study assesses radon and thoron concentrations in drinking water sources within the volcanic region of Nkongsamba, Cameroon.

Evaluation of the Sorption Properties of Diatomite for Capture of Radioactive Barium, Cobalt, and Zinc

International Journal of Chemical Engineering, Volume 2026, Issue 1, 2026.
Sorption is a well‐known method for radionuclide removal, but the high cost of synthetic sorbents constrains its application. This study investigates the potential of locally sourced diatomite from Kariandusi, Kenya, as a cost‐effective sorbent for capturing barium (Ba), cobalt (Co) and zinc (Zn) from radioactive liquid waste.

Assessment of Indoor Radon Exposure Risks in Relation to Dwelling Types in Gold‐Mining Communities of Akyempim, Wassa East District, Ghana

Indoor Air, Volume 2026, Issue 1, 2026.
This study investigated the effects of dwelling type, wall and floor coverings, radium‐226 concentration, soil moisture, and radon exhalation on indoor radon‐222 levels in the gold‐mining community of Akyempim, Ghana. Indoor radon was monitored using CR‐39 solid‐state nuclear track detectors deployed in 144 rooms across 21 sites for 90 days ...

Spatial distribution of radon concentration and risk evaluation through consumption of groundwater in the District of Kotli, Azad Jammu and Kashmir

Kuwait Journal of Science
Radon (222Rn) is naturally readily water-soluble, posing a cancer risk to the exposed community. Human exposure in the community may occur via 222Rn intake in drinking water.

Evaluation of Natural Radioactivity and Radiological Hazards Associated With Earthen Building Materials Commonly Used in Bureti, Kericho County, Kenya

The Scientific World Journal, Volume 2026, Issue 1, 2026.
This study investigates the radioactivity due to naturally occurring radionuclides in earthen building materials commonly used in Bureti, Kenya. Building materials derived from the earth’s crust often contain naturally occurring radionuclides, which may pose radiological health risks. In regions such as Bureti, Kenya, where earthen materials are widely
