137Cs distribution among annual rings of different tree species contaminated after the Chernobyl accident

Title: ¹³⁷Cs distribution among annual rings of different tree species contaminated after the Chernobyl accident

Keywords: Chernobyl; Radioactivity; Radionuclides; Betula pendula; Pinus sylvestris; Radiocaesium; Tree rings; Radial distribution

Abstract: The distributions of ¹³⁷Cs among annual rings of Pinus sylvestris and Betula pendula at four experimental sites located in the most contaminated areas in the Russian territory after the Chernobyl accident in 1986 were studied. Trees of different ages were sampled from four forest sites with different tree compositions and soil properties. The data analysis shows that ¹³⁷Cs is very mobile in wood and the 1986 rings do not show the highest contamination. The difference between pine and birch in the pattern of radial ¹³⁷Cs distribution can be satisfactorily explained by the difference in radial ray composition. ¹³⁷Cs radial distribution in the wood can be described as the sum of two exponential functions for both species. The function parameters are height, age and species dependent. The distribution of ¹³⁷Cs in birch wood reveals much more pronounced dependence on site characteristics and/or the age of trees than pines. The data obtained can be used to assess ¹³⁷Cs content in wood.

Bioindication of the anthropogenic effects on micropopulations of Pinus sylvestris, L. in the vicinity of a plant for the storage and processing of radioactive waste and in the Chernobyl NPP zone.

Keywords: Bioindication; Pinus sylvestris L.; Chromosome aberrations; Chernobyl accident

Abstract: Results of a comparative analysis of the frequency and spectrum of cytogenetic anomalies are presented for reproductive (seeds) and vegetative (needles) samples taken from Scotch pine (Pinus sylvestris, L.) micropopulations growing at sites with differing levels of radioactive contamination in the Chernobyl NPP 30 km zone, and at the location of a facility for the processing and storage of radioactive wastes (the ‘Radon’ LWPE, near the town of Sosnovy Bor in the Leningrad Region). The data obtained indicate the presence of genotoxic contaminants in the environment of the tree micropopulations. Chemical toxins make the main contribution to the environmental contamination in the Sosnovy Bor area as compared with the influence of ionising radiation in the Chernobyl 30 km zone. The higher radioresistance of seeds of Scotch pine growing on the area of the ‘Radon’ LWPE and in the centre of Sosnovy Bor town was revealed with acute γ-radiation.

Rapid land use change after socio-economic disturbances: the collapse of the Soviet Union versus Chernobyl

Reference: Environmental Research Letters, 6 (4), Oct 2011

doi: http://dx.doi.org/10.1088/1748-9326/6/4/045201

Keywords: coupled human–natural systems, socio-economic disturbance, Chernobyl nuclear disaster, post-socialist land use change, transition economies, Soviet Union

Abstract: Land use change is a principal force and inherent element of global environmental change, threatening biodiversity, natural ecosystems, and their services. Here we explored to what extent socio-economic disturbances can shift land use systems onto a different trajectory, and whether this can result in less intensive land use.
