Abstract Groundwater nitrate (NO 3-) pollution has attracted widespread attention; however,
accurately evaluating the sources of NO 3-and their contribution patterns in regional …

High-elevation mountains have experienced disproportionately rapid warming, yet the effect
of warming on the lateral export of terrestrial carbon to rivers remains poorly explored and …

The chemical weathering of silicate rocks can yield bicarbonate which is transported via
rivers to the ocean, followed by the deposition of carbonate, acting as a carbon sink on long …

Coal mining cities are universally confronted with the degradation of groundwater quality,
and the sulfate pollution of groundwater has become a widely studied environmental …

Groundwater quality continues to be threatened globally by anthropogenic activities
including excessive use of chemical fertilizers and sewage discharge. However, few studies …

The balance between alkalinity generation by carbonate and silicate weathering and sulfuric
acid generation by sulfide weathering controls the effect of weathering on atmospheric pCO …

The source and evolution of sulfate (SO 4 2−) in groundwater from abandoned mines are
widely concerned environmental issues. Herein, major dissolved ions, multi-isotopes (δ 34 …

Carbon dioxide (CO2) emissions from aquatic ecosystems are an important component of
the karst carbon cycle process and also a key indicator for assessing the effect of karst …

Pyrite oxidation coupled with carbonate weathering can be a source of carbon dioxide (CO
2) to the atmosphere over geological timescales. However, this source of CO 2 is an …

Accurate estimate of carbon sink flux resulted from carbonate weathering in the karst area is
of great significance for advancing the current understanding of the global carbon cycle and …
