“…It can be assumed that the greater accumulation of 137 Cs in birch wood than in pine trees in the oldest stands noted in our study is due to the greater activity of this isotope in birch bark than in pine bark. The bark of trees is a good bioindicator of air pollutants, including heavy metals [45][46][47][48][49]. Taking into account the obtained data, it can be concluded that stands over 75 years of age can be used to assess radioactive contamination of the environment in the past; due to the greater activity of 137 Cs, birch stands seem to be more useful for bioindication purposes than pine stands.…”

Research Highlights: a forest is an ecosystem that allows for the assessment of radioactive contamination of the environment over several decades. (1) Background and Objectives: measurements of the activity of the 137Cs isotope in various elements of a forest ecosystem are one of the most important parameters in the assessment of radioisotope contamination. The translocation of 137Cs in the environment is determined by the activity of the natural 40K isotope in soil. The activities of 137Cs and 40K isotopes were assessed in two stands of Betula pendula and Pinus sylvestris, differing in age (30, 50, and 80 years old); (2) Materials and Methods: the research was conducted in one of the forest districts of eastern Poland. Wood, litter, and soil were collected for the tests from the sampling sites. The activity of 137Cs and 40K was determined using the γ-spectrometric method. Based on the activity of these isotopes in wood and soil, the values of translocation factors (TF) were determined; (3) Results: the highest activity of 137Cs was recorded in the wood of the oldest stands, the growth period of which coincided with the time period of intensive testing with nuclear weapons. With the growing age of the stand, the value of TF 137Cs increased, while the value of TF 40K was not dependent on the age of the stands. Birch wood accumulated more 137Cs and 40K isotopes than pine wood. (4) Conclusions: the results show a much greater radioactive contamination of the environment in eastern Poland during the testing with nuclear weapons than after the Chernobyl nuclear reactor explosion. The greater accumulation of radiocesium in birch wood than in pine wood predisposes this species to be more useful when assessing the radioactive contamination of the environment from the past.

“…However, in the same study Cd was detected in the samples (between 1.526 ± 0.012 mg/kg and 1.639 ± 0.015 mg/kg), and also higher contents of Pb were recorded (between 13.848 ± 0.159 mg/kg and 14.950 ± 0.167 mg/kg) compared to our results (Yalcin et al 2020). Parzych et al recorded higher contents of Ni in P. sylvestris (90.6 ± 2 mg/kg) and P. nigra (80.5 ± 2 mg/kg) bark samples and also detected Cd in these samples (1.2 ± 0.7 mg/kg for P. nigra and 2.1 ± 1.6 mg/kg for P. sylvestris) (Parzych et al 2017) metal ranges: between 1.0 ± 0.4 mg/kg and 1.9 ± 0.7 mg/kg for Ni; between 0.3 ± 0.1 mg/kg and 1.4 ± 0.6 mg/kg for Cd and between 2.9 ± 0.8 mg/kg and 4.0 ± 1.2 mg/kg for Cr (Sut-Lohmann et al 2020). All these results show that the heavy metal contents' vary depending on the collecting location.…”

Extracts obtained from the bark of woody plants are used for their high content in polyphenolic compounds with various biological activities. Thus, it is important to evaluate the heavy metals in various tree barks, as these pollutants may end up in the final product, affecting its properties and having potential health implications. This study assessed the heavy metal content in the barks of spruce (Picea abies) and pine (Pinus sylvestris and Pinus nigra) collected from different areas in Romania. After collecting the vegetal material from different sites, the bark samples were appropriately processed and analyzed via inductively coupled plasma optical emission spectroscopy (ICP-OES). The results showed that 6 out of 8 tested samples exceeded the normal values of selenium (Se). Arsenic (As) and cadmium (Cd) were not detected in any sample, while other metals (chromium (Cr); lead (Pb); nickel (Ni)) were detected in variable amounts. Moreover, relatively high levels of heavy metals were recorded in a spruce bark sample collected from the seemingly most unpolluted site. Although further studies are needed to determine the effects of these heavy metals on extraction yields and their transfer into the final extracts, their presence might indicate a potential problem.

“…Subsequently, about 0.250 g of soil material was digested using 8 mL of 65% HNO 3 using a Mars G microwave system (20 min at 200°C). Ni, Cu, Pb, Zn, and Cr analysis was performed by plasma atomic emission spectrometry (Agilent 4100 MP‐AES) (Sut‐Lohmann et al, 2020). All the measurements were conducted using two replicates, and certified reference materials Merck Certipur™ were used to control soil analysis quality and instruments calibration.…”

Sewage disposal onto agricultural land may result in the high accumulation of organic wastes, which questions the applicability of typical elemental analysis used for the soil components. To monitor the contamination status of agricultural soils at a former sedimentation basin, after the long‐term cessation of wastewater irrigation, 110 locations (15–20 cm depth) and 4 boreholes (up to 100 cm depth) were sampled to determine pH, loss on ignition, and concentration of Ni, Cu, Pb, Zn, and Cr. Additionally, the applicability of portable X‐ray fluorescence (pXRF) for the soil samples highly influenced by the organic wastes was evaluated. The study revealed the presence of a relatively homogenous sewage waste layer (depth of 20 cm), characterized by slightly acidic to neutral pH (6.3–7.5), high organic matter (OM) accumulation (up to 49%), and elevated concentration (mg kg −1) ranges between: Pb (5–321), Cu (31–2828), Ni (10–193), Cr (14–966), and Zn (76–6639). The pXRF analysis revealed metal concentration increase in mineral samples (up to 50%). The regression models and correction factors demonstrated high correlation and significance of pXRF measurement with response to increasing OM content, with the lowest r 2 = 0.86 obtained for Ni. Correlation of pXRF and AES measurement illustrated element‐dependent response for soils high in organics. Zn, Cu, and Cr pXRF analysis led to a slight underestimation in lower values, but overall good correlations (0.87; 0.89; and 0.88 respectively). Pb and Ni pXRF measurement revealed higher deviation from the reference in both lower and higher concentrations (0.74 and 0.70, respectively).
