Assessment of a Possibility of the Use of Aquatic Macrophytes for Biomonitoring and Phytoindication of the Contamination of Natural Waters by Heavy Metals

摘要

Accumulation of heavy metals by aquatic macrophytes of various ecological groups was investigated. It has been shown that the degree of metal accumulation by macrophytes is indicative of the degree of anthropogenic load on aquatic ecosystems. It has been found that the highest coefficients of metal accumulation are observed in submerged macrophytes (Ceratophyllum demersum, Myriophyllum spicatum, and Potamogeton perfoliatus). Thus, these species can be used in the system of biomonitoring and phytoindication of the contamination of the aquatic environment by heavy metals. In terms of the degree of their accumulation in macrophytes, the studied metals can be arranged in the following order: Mn Fe Zn Cu, Ni, Pb Co Cd.
