Determining freshwater pCO(2) based on geochemical calculation and modelling using PHREEQC
Fossil fuel combustion results in rising atmospheric carbon dioxide (CO(2)), which is known to impact the global climate and the oceans. Latest insights indicate that rising atmospheric CO(2) levels also affect CO(2) partial pressure (pCO(2)) in freshwaters, where pCO(2) is controlled by a multitude...

Fossil fuel combustion results in rising atmospheric carbon dioxide (CO(2)), which is known to impact the global climate and the oceans.

However, up to date there is no standardized method, which allows the determination of current and past freshwater pCO(2) levels. Ideally methods should incorporate numerous hydrogeochemical and -physical factors to reflect the interplay of all interacting components and their effect on pCO(2).
