Is a universal model of organic acidity possible: Comparison of the acid/base properties of dissolved organic carbon in the boreal and temperate zones

Original language description

The acid/base properties of dissolved organic carbon (DOC) are an important feature of soil and surface waters. We used a combination of ion-exchange techniques, titration, and surface water chemistry data to evaluate DOC character from two substantiallydifferent areas - the relatively pristine boreal zone of Sweden and the heavily acidified temperate zone of the Czech Republic. We found a significantly higher site density (amount of carboxylic groups per milligram of DOC) for the Swedish sites (10.2 eq/mg of DOC +/- 0.6) as compared to the Czech sites (8.8 ueq/mg of DOC +/- 0.5). This suggests a slightly higher buffering capacity for Swedish DOC. A triprotic model of a type commonly incorporated in biogeochemical models was used for estimating the
