Ostroumov S.A., Shestakova T.V. Decreasing the measurable concentrations of Cu, Zn, Cd, and Pb in the water of the experimental systems containing Ceratophyllum demersum: The phytoremediation potential. - Doklady Biological Sciences, 2009, vol. 428, no. 1, p. 444-447. Finding: aquatic plants (macrophytes) C. demersum induced a removal of the heavy metals Cu, Zn, Cd, and Pb from water.
http://5bio5.blogspot.com/2012/09/ostroumov-sa-shestakova-tv-decreasing.htmlChanges in the concentrations of the four heavy metals in the water of experimental systems were studied. Using the method of inversion voltamperometry, the concentrations of the heavy metals Cu, Zn, Cd, Pb were measured in the water of the experimental microcosms. Aquatic macrophytes Ceratophyllum demersum were incubated in the microcosms. The measured concentrations of all four heavy metals decreased in the microcosms with the macrophytes much faster than in the control microcosms without any aquatic plants. The new results complement the previous data on the phytoremediation potential of aquatic plants. The new facts proved that Ceratophyllum demersum is a potent tool to clean water and to remove heavy metals. This is the first time the phytoremediation potential (for the mixture of metals) of this wide-spread species was discovered. The plant removed the toxic metals cadmium, lead, copper, zink (Cd, Pb, Cu, Zn) from water with great efficiency. As a result, water quality improved dramatically with a prospect of new technology.
