Characterizing and Classifying Rainfall‐Runoff Response, Storage Variability and Water Quality Dynamics in a Small, Forested Catchment

Hydrological Processes, Volume 40, Issue 10, October 2026.
Most rainfall‐runoff events were characterized by strong shallow subsurface flow contributions, apart from two very heavy rainfall events that could have generated overland flow. Variability was observed in streamflow‐groundwater dynamics, with groundwater peaking before and/or after streamflow in different groundwater wells, and in water quality ...

Environmental pollution and sustainable restoration of the Yamuna River: A review of water quality, health risks, and phycoremediation

River, Volume 5, Issue 3, Page 398-418, August 2026.
Abstract The Yamuna River, one of India's most significant river systems and the largest tributary of the Ganges River, serves critical ecological, socio‐economic, and cultural functions. However, rapid urbanization, industrialization, and intensive agriculture have severely degraded its water quality, resulting in extensive pollution with untreated ...

Exploring Interactive Effects of Arsenic and Selenium Exposure on Larval Zebrafish (Danio rerio)

Environmental Toxicology, Volume 41, Issue 10, Page 1027-1040, October 2026.
ABSTRACT Arsenic contamination in aquatic ecosystems is a major environmental concern. Selenium (Se) helps mitigate oxidative stress and hence could reduce the toxic effects of arsenic. However, Se can also be toxic at high concentrations. Given that these metalloids commonly co‐occur in the environment, there is a pressing need for further research ...

TRACE METAL ANOMALIES IN SOILS AND SEDIMENTS OF THE MOANDA-BANANA COASTAL AREA (CONGO COASTAL BASIN): RELATIVE ROLES OF ANTHROPOGENIC PROCESSES AND DEEP GEOGENIC CONTROLS

Romanian Journal of Petroleum & Gas Technology
This study investigates the controls governing the spatial distribution of trace metals (TMs) in soils and coastal sediments of the Moanda-Banana sector within the Congo Coastal Basin. The objective is to discriminate the relative roles of near-surface sedimentary processes and deeper geogenic influences in the development of metal anomalies within an ...

Strong‐Acid Weathering in a Carbonate‐Siliciclastic Cropland Diminishes Removal of CO2 From the Atmosphere Without Becoming a CO2 Source

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 10, October 2026.
Abstract One strategy to remove carbon dioxide (CO2) from the atmosphere is to accelerate weathering in croplands by adding powdered rock. Both silicate and carbonate minerals can be effective as amendments, but strong acids from rain and fertilizer diminish CO2 removal and can promote degassing of CO2 from carbonate minerals (geogenic CO2).

Rapid Increase in Geogenic CO2 Emissions from Antarctic Permafrost

Global Biogeochemical Cycles, Volume 40, Issue 10, October 2026.
Abstract Thawing permafrost can amplify climate change by releasing previously stored carbon, but observations of this feedback come mainly from the Arctic. Ice‐free Antarctic terrains are generally regarded as minor CO2 sources, although sub‐permafrost brines and deep carbon reservoirs may support localized geogenic degassing.
