Chemistry of Dissolved Organic Carbon and Organic Acids in Two Streams DrainingForested Watersheds

摘要

The concentration, major fractions, and contribution of dissolved organic carbon(DOC) to stream chemistry were examined in two paired streams draining upland catchments in eastern Maine. Although SO(-2) was the dominant stream anion, followed by Cl(-), organic anions were also determined to be an important component of these stream waters, especially during storm events. This illustrates that even in streams with low DOC, such as these studied here, organic anions can contribute significantly to stream acidity.
