| dc.description.abstract | A sedge fen on Mount Washington, 23 km west-northwest of Courtenay, British Columbia, was identified as removing copper, iron, aluminum, arsenic and sulphate from a stream, Pyrrhotite Creek, flowing through it. Samples of the Narrow-Leaved Cotton Grass, Eriophorum angustifolium, a sedge, contained over 1000 ppm. copper. Production of cotton grass leaf mass was -109 gm/square metre/summer. Harvesting cotton grass was not feasible as a means of removing copper. Copper into the plants was insignificant compared to the copper being removed from the copper-rich water and retained in the sedge peat soil of the fen. Processes removing copper from the water of Pyrrhotite Creek appeared to be: Adsorption by organic soil components. Adsorption onto iron oxyhydroxides. Formation of copper and/or copper and iron sulphides (chalcocite, covellite, chalcopyrite, etc.). Narrow-Leaved Cotton Grass has the potential of being used as cover in contaminated sites as it is extremely adaptable. | |
