“…According to the calculation by Yoschenko et al (2006b), agreeing with their experimental data, up to 3-4% of 137 Cs can be released from the forest litter during a forest fire. In the course of resuspension experiments in Zapolie (14 km from the Chernobyl reactor) in 1992-1993, only about 20% of the deposited activity was still available in the top soil layer (0-1 cm), while about 80% of total activity was found in the layer up to 5 cm deep (Garger et al, 1998).…”

“…Models have been developed [7] to predict parameters of radionuclide resuspension, transport and deposition during forest and grassland fires. The prognostic power of the models was furthermore tested through comparison with experimental data of controlled burning of prepared experimental plots in the Chernobyl exclusion zone [8].…”

Abstract. This article summarises some key activities undertaken as part of a NATO-funded project to map and improve our understanding of the behaviour and fate of radionuclides in the Belarusian Sector of the Chernobyl Exclusion zone. Data are presented concerning activity concentrations of 137 Cs, 90 Sr and selected actinides and how these data have been used to produce contour maps of contamination densities. Factors affecting the transfer of radionuclides to plants and animals at selected study sites are considered and the geochemical phase association of radionulcides in soils and implications for actinide mobility commented upon. A final important subject for elaboration has been the transboundary transport of contamination by natural phenomena. The influence of forest fires on remobilisation of radionuclides, for example, has been addressed through the application of a bespoke probabilistic model.

“…However, high metal concentrations occur naturally in ecosystems as a consequence of pedogenetical processes (Pacyna and Pacyna 2001), volcanic activity (Allard et al 2000), and forest fires (Yoschenko et al 2006). Several metals are essential for plants, and this dependence has been acquired in the course of evolution because of the metals' chemical properties, such as redox activity under physiological conditions (Cu, Fe) and Lewis acid strength (Zn) (Clemens 2006).…”

Current-year, 1-year-old, and 2-year-old needles were collected separately on 37 black spruce (Picea mariana Mill. B.S.P.) trees located on a heavy metal contamination gradient around the smelter in Murdochville, Québec (Canada). Needles were analyzed separately by year for the concentrations of Pb and Cu, a nonessential and an essential metal, respectively. Lead concentrations increased significantly with needle age in the highly contaminated area near the smelter. In contrast, Cu concentrations decreased with needle age in the same area. Our results support the hypothesis that the passive sequestration of toxic metals in the senescing foliage is a detoxification process contrasting with the active translocation of essential metals in the nonsenescent part of the foliage.
