222Rn Premonitory signals for earthquakes?

Eos, Transactions American Geophysical Union, 1992
Are changes in 222Rn concentrations in the Earth of use in predicting earthquakes? This is a nagging issue, there being many scattered data that are suggestive of useful signals, but none that have been established firmly by accepted statistical analysis. Figure 1 illustrates the quandary.

Groundwater Discharge as a Critical Driver of Freshwater Lake Acidification in Central China

Water Resources Research, Volume 61, Issue 8, August 2025.
Abstract Lake acidification has emerged as a widespread environmental challenge globally, yet the role of lacustrine groundwater discharge (LGD) in this process remains poorly understood. Here, through seasonal monitoring of lake pH and LGD‐derived total alkalinity (TA) and dissolved inorganic carbon (DIC) fluxes in a hydrologically representative ...

Analysing Temporal Variations in Radon Concentrations: Identifying Trends and Changes

Terra Nova, Volume 37, Issue 4, Page 263-274, August 2025.
ABSTRACT Radon is a well‐known precursor for geodynamic events such as earthquakes and volcanic tremors. Radon concentration variations in soil gas have been monitored worldwide, and extreme radon values have been identified as radon anomalies associated with geodynamic events.

Radiocarbon analysis reveals decomposition of old soil organic carbon into dissolved inorganic carbon in a subtropical mangrove ecosystem

Limnology and Oceanography, Volume 70, Issue 6, Page 1740-1754, June 2025.
Abstract The outwelling of remineralized dissolved inorganic carbon (DIC) from the subsurface soil layer through tidal pumping has recently been noted for its importance in the blue carbon budget of mangroves. However, the age of soil organic carbon (SOC) that has been decomposed into DIC remains uncertain.

Hydrochemistry and 222Rn Concentrations in Spring Waters in the Arid Zone El Granero, Chihuahua, Mexico

Geosciences, 2017
Water in arid and semi-arid environments is characterized by the presentation of complex interactions, where dissolved chemical species in high concentrations have negative effects on the water quality.

A mangrove nitrous oxide sink attenuates methane climate impacts

Limnology and Oceanography Letters, Volume 10, Issue 3, Page 298-307, June 2025.
Abstract We resolve mangrove nitrous oxide (N2O), methane (CH4), and carbon dioxide (CO2) vertical exchange with the atmosphere and lateral exchange with the ocean. Our new observations in Brazil were combined with literature data to reassess the overall mangrove carbon sequestration potential.

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.
