Organic Acids in Aquatic Ecosystems E. M. Perdue E. T. Gjessing Editors This volume consists of background papers and reports on discussions focused on identifying major processes that cause spatial and temporal variability in properties and concentrations of organic acids in aquatic ecosystems. Scientists in aquatic chemistry, environmental chemistry, soil chemistry, organic geochemistry, water treatment technology, forest ecology, and stream ecology collectively address four major questions:
- What is the composition of organic acids and how are they characterized?
- How are acid-base properties of "DOC" measured and modeled and how do they affect aquatic ecosystems?
- How do organic acids interact with solutes, surfaces, and organisms?
- What are the temporal and spatial variations of organic acids at the ecosystem level?
