Thus, quality of organic matter in surface waters depends on biologic and hydrologic properties of the system and on regional climate.

Sources and Age of Aquatic Humusng from about 500 D for dissolved fulvic acid to greater than 100,000 D for humic acids in sediments. Although the heterogeneity of these humic fractions makes rigorous chemical studies challenging, there are sufficient analytical methods at hand to make progress toward understanding the sources, formation pathways, and fate of aquatic humus.
