The content of heavy metals in macrophytes of the fishery ponds ASUE "Rybkhoz" Pikhtovka" (Udmurt Republic)

The results of studying the contents of five heavy metals (Fe, Mn, Ni, Zn, Cu) in the vegetative organs of macrophytes ( Carex acuta, Equisetum fluviatile, Phragmites australis, Typha angustifolia, T. latifolia ) growing in fishery ponds ASUE "Rybkhoz "Pikhtovka" (Udmurt Republic) are presented. The quality of aquatic habitat despite on exceeding the standards of the threshold limit value (TLV) of some metals in general normal is shown. Biotechnical measures were proposed for the prevention of pollution of aquatic ecosystems with heavy metals.
