Acid-induced changes in DOC quality in an experimental whole-lake manipulation

Article Abstract:

The accumulation of acid compounds in water bodies has been found to induce detrimental effects on water quality, as revealed by statistics gathered from Experimental Lake Ares in Ontario. Acidification in these areas did not only cause a significant increase in the concentration of dissolved organic carbon, but exposed animals to greater risks of acquiring ultraviolet defects, as well. These changes may be attributed to the increased precipitation of UV-absorbent aromatic portion of DOC molecules or heightened chemical oxidation.

Impacts of flow restrictions on salt marshes: an instance of acidification

Article Abstract:

The restriction of the tidal flow to a salt marsh located in Guilford, CT, caused the development of increased nutrient levels and lowered alkalinity in the sediment and led to the development of severe acidification once water was reintroduced to the sediment layer. The increased acidity level also resulted in the mobilization of metals such as lead, copper and cadmium.
