“…Studies carried out on this subject include the effect of metals on humans, animals, and plants. Analyses of the effect of heavy metals on plants, including forest trees, were conducted by Lovrencic et al (2008), Szymura (2009) and Zacchini et al (2009) and the problem was discussed by Maksymiec (2007).…”

The aim of the presented research was to investigate the effect of three heavy metals - lead, cadmium and copper - on the callus cells of Abies nordmanniana. The toxicity degree and toxicity effect of the selected heavy metals was determined on the embryonic level. On the basis of the spectrometric analyses as well as macroscopic and microscopic observations, this research referred to the accumulation of heavy metals in tissues, assuming that this mechanism is related to the acquisition of tolerance by cells exposed to this type of abiotic stress. Moreover, the effect of the genotype of fir on the cell defence, that is, the induction of tolerance, was analysed. Understanding of the issues related to the heavy metal resistance of plant genotypes in future may contribute to the selection of genotypes of individuals that are more resistant to stress factors, particularly in the multi-directional and rational forest management. The results showed that lead (20 mg l-1), which proved to be the most toxic amongst the three examined heavy metals, has the most severe negative effects on the tissue of fir trees. Copper (20 mg l-1) was accumulated for a long time in the cells of fir trees, and it was not degraded or excreted outside the tissues even after three weeks of in vitro culture. Of the three tested genotypes, G14 had the greatest tendency to accumulate each of the examined metals, that is, it appeared to be the least tolerant genotype.

In the present study, the bark of oak trees (Quercus petraea Liebl.) was collected from Belgrade Forest northwest of Istanbul for determination of 137Cs, 40K, 232Th, and 238U activity. A gamma spectrometer equipped with high-purity germanium detector was used for radioactivity measurement. Bark samples were collected from the northern and southern sides of trees at a height of 1.5 m above the ground in order to see the effects of rainfall and wind; and they were also collected from the northern side at a height of 0.5 m above the ground to assess the effect of soil splash. The activity concentrations of 137Cs, 40K, 232Th, and 238U in the bark samples were found to vary in the range of 1.40-27.50, 45.0-221.2, 0.92-9.64, and 4.04-36.10 Bq/kg, respectively. The elevated activity of 238U in bark samples could be attributed to a large amount of coal combustion in the region until the 1990s. According to one-way ANOVA, a significant difference was not found in bark samples collected at a height of 0.5 m and 1.5 m above the ground in terms of radionuclide activity. There was also no significant variation regarding radionuclide accumulation between northern and southern sides

“…The artificial radionuclide 137 Cs is a member of the same homologous series to which the natural radionuclide 40 K belongs and, although 40 K is a natural radionuclide, the competitive effects of caesium and potassium cannot be ruled out [12]. This assumption is confirmed by research [13]: 137 Cs is involved in different physiological processes in a way similar to 40 K. This is somewhat expected since caesium and potassium are homologous elements.…”

Radioactive pollution entered the ecosystems during the nuclear test in the 1950s and 1960s and in Croatia largely after Chernobyl accident in 1986. 137 Cs and 40 K can be stored in different parts of the trees but also in the upper surface layer of soil under the trees. This study was aimed at determining the intensity and dynamics of 137 Cs and 40 K radionuclides in chestnut tree tissues (Castanea sativa Mill.) in the vicinity of Petrinja (Croatia). The samples were taken in 2003, 2004 and 2016 and the samples activities were measured by gamma spectrometric method. During the winter, the highest activities were recorded in the top shoots, leaves, fruits and hedgehogs, while in the vegetation season, the highest activities were in the top shoots and dead bark. Also, a decrease in 137 Cs concentrations was observed in the rings with increasing age of the rings. Significant increased values of activity were measured in samples of the youngest and physiologically most active parts of trees, compared to the least physiologically active where concentrations were lower. 137 Cs was biogeochemically retained almost entirely in the surface layer. The obtained results suggest that the chestnut tree does not distinguish 137 Cs and 40 K, as two homologous elements.
