    Cytogenetic abnormalities in aquatic plant Elodea canadensis in anthropogenic contamination zone of Yenisei River [Text] / M. Y. Medvedeva, A. Y. Bolsunovsky, T. A. Zotina // Contemp. Probl. Ecol. - 2014. - Vol. 7, Is. 4. - P422-432, DOI 10.1134/S1995425514040088. - Cited References: 19. - The authors thank their colleagues from the Radioecology laboratory and Analytical laboratory for gamma spectrometric and chemical analyses. The authors express their appreciation to O.V. Kvitko (Institute of Forest, Siberian Branch, Russian Academy of Sciences, Krasnoyarsk) for her valuable methodical consultations. This research is partially funded by both a RFFI-r_Siberia-a, grant no. 13-04-98004 from the Russian Foundation for Basic Research and project no. 30.5 of the Biological Diversity Program of the Presidium of the Russian Academy of Sciences. . - ISSN 1995-4255. - ISSN 1995-4263

Аннотация: Chromosome abnormalities in ana-telophase cells of apical root meristem of aquatic plant Elodea. canadensis (elodea), sampled in 2011-2012 in the Yenisei River at a site with background level of contamination and at several sites on the stretch contaminated with artificial radionuclides, and with chemical pollutants from municipal and industrial discharges of the Krasnoyarsk city. Lowest rate (5.2%) of cells with chromosome abnormalities was registered at sampling site with background level of contamination upstream of the Krasnoyarsk, highest rate of cells with abnormalities (39.7%)-in roots of elodea sampled in bottom sediments with highest concentration of Cs-137. Sum of rates of cells with abnormalities and rates of cells with all types of abnormalities positively correlated with total concentration of artificial and natural radionuclides, with concentration of artificial radionuclides and Cs-137 in bottom sediments of the Yenisei River (r (2) = 0.91-0.96, p < 0.0005 for sum of rates of cells with abnormalities; r (2) = 0.58-0.92, p < 0.05 for all types of abnormalities).
