Estimation the extent pollution by heavy metals the Moscow river, and possibility of use the Potamogeton macrophytes for biomonitoring the heavy metals in the river

In article the question of pollution the water and ground deposits of the Moscow river by heavy metals: Mn, Fe, Sr, Zn, Cr, Ni, Cu, Pb, Cd, Co is considered. Researches are conducted during the summer period of 2012 on a site of the river from lower byef of Mozhaisk reservoir to the estuary of the river near Kolomna. Excess of standards for water currents of cultural and community use for pollution by heavy metals (Fe, Mn, Cd) river waters is revealed. Sites of the river with concentration of heavy metals exceeding the level of regional background for ground deposits are established. Heterogeneity of distribution the concentration of metals in water and ground deposits on sites of the current is higher than Moscow below, is shown. Opportunity is considered and practical recommendations about use of three types of rdest ( Potamogeton pectinatus L., Potamogeton perfoliatus L. and Potamogeton lucens L.) for biomonitoring the heavy metals in the river are made.
