“…Plants are particularly exposed to environmental pollutants since they are stationary and unable to leave the contaminated zone; thus they cannot avoid harmful influences and must adapt to life in a harsh environment. An adaptation process in plant populations experiencing man-caused exposure was investigated in our long-term study [8]. The Scots pine populations growing in the vicinity of a radioactive waste storage facility and at sites with differing levels of radioactive contamination in the 30-km Chernobyl NPP zone were characterized (Fig.…”

Abstract. Results of laboratory, "green-house" and long-term field experiments carried out on different plant species (spring barley, Scots pine, bulb onion and others) to study ecotoxical effects of low doses and concentrations of such common environmental factors as acute and chronic γ-radiation, heavy metals, pesticides, artificial and heavy natural radionuclides, are presented. Special attention is paid to ecotoxic effects of chronic low dose exposures, synergistic and antagonistic effects of different factors' combined action. The results of long-term field experiments in the 30-km Chernobyl NPP zone and in the vicinity of a radioactive wastes storage facility are discussed. The data presented suggest that the further evolution of investigations in this field would issue in the development of a theoretical bases and practical procedures for environmental protection against radioactivity, taking into account the new experimentally confirmed facts about the presence of such essentially important singularities as the nonlinearity of a dose-effect relationship, radiation-induced genomic instability, phenomenon of radioadaptation, increased probability of synergetic and antagonistic effects of the combined action of different nature factors.

“…Diverse morphological and genetic defects that have been present in plants inhabiting the contaminated areas to-date include changes in size, shape, and color of individual organs and their location in the plants (Shevchenko and Grynikh 1995;Frolova et al 1996;Geraskin et al 2003a;Pozolotina 2003, Oudalova et al 2005. Specifically, numerous morphological defects have been detected in Scots pine (Pinus sylvestris) (Kal'chenko et al 1993a(Kal'chenko et al , 1993bRubanovich and Kal'chenko 1994;Grodzinsky et al 1995;Geraskin et al 2003b). Scots pine trees, on one hand, are very sensitive to radiation and, on the other hand, they are the major forest-forming species in the Chernobyl Exclusion Zone (ChEZ).…”

To identify effects of chronic internal and external radiation exposure for components of terrestrial ecosystems, a comprehensive study of Scots pine trees in the Chernobyl Exclusion Zone was performed. The experimental plan included over 1,100 young trees (up to 20 years old) selected from areas with varying levels of radioactive contamination. These pine trees were planted after the 1986 Chernobyl Nuclear Power Plant accident mainly to prevent radionuclide resuspension and soil erosion. For each tree, the major morphological parameters and radioactive contamination values were identified. Cytological analyses were performed for selected trees representing all dose rate ranges. A specially developed dosimetric model capable of taking into account radiation from the incorporated radionuclides in the trees was developed for the apical meristem

“…Thus, the data suggest strongly a presence of some mutagenic contaminants in the environments of pine populations A and B. At an analysis of aberration spectra [9], tripolar mitoses, rather rare anomalies, were found in the samples from both populations B and A. Their appearance is possibly linked to spindle damage [13,14].…”

“…To study whether natural populations have experienced environmental stress in areas with relatively low levels of pollution, Pinus sylvestris L. populations growing in a vicinity of nuclear facilities in Leningrad region of Russia were monitored in 1997-2002. Preliminary cytogenetical findings were published in [9]. Since than, experimental data have been significantly stocked up.…”

Cytogenetic variability in PInus sylvestris L. populations experiencing anthropogenic influence

et al. 2005

View full text Add to dashboard Cite

Abstract. Pinus sylvestris L. populations growing at the territory affected by nuclear waste storage facilities were monitored in 1997-2002. Cytogenetic damage levels within root meristem of seedlings significantly exceed corresponding controls. Populations experiencing man-caused influence have a higher seeds radioresistance and enlarged cytogenetic variance. These are considered as an indication of adaptation processes in the studied pine populations. An analysis of the structure of ecological-genetical variability is carried out. Changes of two components of the intrapopulational variance were studied in dependence on time and man-caused impact. The first component is engaged to the genetically determined variability of biological characteristics intrinsic for the species and is dominant in studied tree populations. The second is responsible for the variance originating from anthropogenic contamination of the natural habitat. A tendency of destabilizing dynamics and increasing mean values of intraclass correlation coefficient that is a measure of contribution from heterogeneity among trees into total cytogenetical variability is demonstrated under conditions of chronicle technogenic impact on pine populations.
