“…Džoljić et al (2017) reported very low TF Cs for spruce needles (range from not detected to 0.02), which could confirm washing out effect and deposition in substrate by precipitation. The most important way of 137 Cs deposition in moss tissue is possibility that 137 Cs remains on the surface, which influences soil resuspension and transport to mosses (Ioannidou & Papastefanou, 2006, Krmar et al, 2018; also, 137 Cs can be transported during growing period from older sections to newer sections of moss tissue (Krmar et al, 2018). Furthermore, physiological and morphological features of the same moss species may vary among localities; it includes different growing ages of moss tissue, different dynamic processes of biosorption by different sections of mosses) and hence, the accumulation of atmospheric fallout may differ (Kiliç et al, 2019).…”

“…Recently, radionuclides in soils and mosses have been investigated in regions of Serbia by many authors (Mitrović et al, 2009;Dragović & Mihailović, 2009;Grdović et al, 2010;Dragović et al, 2010;Čučulović et al, 2012;Mitrović et al, 2016;Krmar et al, 2018). This is the first environmental study which used mosses as indicators of radiological contamination in area of Kosovska Mitrovica and Zubin Potok municipalities, North Kosovo and Metohija.…”

This paper deals with investigations of elemental concentrations and soil-to-moss transfer factors of radionuclides in area of municipalities Kosovska Mitrovica and Zubin Potok. Twelve samples of soil and moss Hypnum cupressiforme Hedw. were collected during May 2018. Transfer factors of radionuclides: 226Ra, 232Th, 40K and 137Cs were calculated with regard to elemental concentrations of radionuclides in soil and moss samples. Analysis was done in order to indicate the different ways of adopting radionuclides by mosses. According to calculated transfer factors and analysis, authors concluded that the soil is dominant source of natural radionuclides and their concentration in moss occurred due to resuspension of soil particles, while artificial 137Cs is present in soil and moss samples as a consequence of atmospheric dry and wet deposition.

“…Radionuclides predominantly come from natural sources, of either cosmic (e.g., beryllium-7 [ 7 Be]; [35]) or terrestrial (e.g., lead-210 [ 10 Pb]; potassium-40 [ 40 K]) origin. The radionuclide 7 Be (half-life 53.3 days) is produced by cosmic rays in the lower stratosphere and upper troposphere, where it is adsorbed by particles and ultimately removed from the atmosphere by wet and dry deposition [36,37]. While 210 Pb (half-life 22.3 y) is a progeny of 222 Rn in the 238 U decay series in soils, a fraction of 222 Rn escapes to the atmosphere where it decays to 210 Pb, is adsorbed by particles, and is removed by wet and dry deposition [38].…”

Influence of Precipitation on the Spatial Distribution of 210Pb, 7Be, 40K and 137Cs in Moss

et al. 2023

Mosses have been widely used as biomonitors of a variety of atmospheric pollutants, including radionuclides. Here we determine the radionuclide activity concentration of 210Pb, 137Cs, 7Be, and 40K in moss tissue (Hylocomium splendens) collected from 24 sites across Ireland and assess the influence of precipitation on radionuclide spatial distribution. Lead-210 was the most abundant radionuclide (range: 226–968 Bq kg–1), followed by 7Be (range: <DL—604 Bq kg–1), 40K (range: <DL—155 Bq kg–1), and 137Cs (range: <DL—41 Bq kg–1). Albeit nearly thirty years since the Chernobyl disaster, 137Cs activity concentration was detected at 67% of the study sites; however, the spatial distribution was not fully consistent with the 1986 Chernobyl deposition pattern. Rather, 137Cs was weakly correlated with rainfall, with higher concentrations along the west coast, suggesting that the 2011 Fukushima Dai-ichi nuclear accident was also a potential source. Average annual rainfall was a significant predictor of 210Pb activity (linear regression, R2 = 0.63, p < 0.001). As such, the highest radionuclide activity was observed for 210Pb (average: 541 Bq kg–1), owing to the high levels of precipitation across the study sites (average: 1585 mm). In contrast, 7Be or 40K were not correlated with precipitation; rather, 40K and 7Be were significantly correlated to each other (rs = 0.7), suggesting that both radionuclides were transferred from the substrate or through soil re-suspension. Precipitation is widely reported as an important factor in the spatial distribution of radionuclides; however, only 210Pb activity concentrations in moss were strongly influenced by precipitation in the current study.

“…In order to determine the atmospheric deposition of trace elements, complicated and expensive classical analytical methods are usually required. However, there is another reliable technique that uses living organisms (grass, leaves, pine needles, mosses, and lichens) in order to study the environmental quality and the effects of trace elements on the 2 of 14 biosphere [8][9][10][11][12][13]. The biomonitoring technique is a rapid, effective, and low-cost technique that can provide data for the atmospheric deposition of trace elements in even remote areas.…”

Moss biomonitoring is a widely used technique for monitoring the accumulation of trace elements in airborne pollution. A total of one hundred and five samples, mainly of the Hypnum cupressiforme Hedw. moss species, were collected from the Northern Greece during the 2015/2016 European ICP Vegetation (International Cooperative Program on Effects of Air Pollution on Natural Vegetation and Crops) moss survey, which also included samples from the metalipherous area of Skouries. They were analyzed by means of neutron activation analysis, and the elemental concentrations were determined. A positive matrix factorization (PMF) model was applied to the results obtained for source apportionment. According to the PMF model, five sources were identified: soil dust, aged sea salt, road dust, lignite power plants, and a Mn-rich source. The soil dust source contributed the most to almost all samples (46% of elemental concentrations, on average). Two areas with significant impact from anthropogenic activities were identified. In West Macedonia, the emissions from a lignite power plant complex located in the area have caused high concentrations of Ni, V, Cr, and Co. The second most impacted area was Skouries, where mining activities and vehicular traffic (probably related to the mining operations) led to high concentrations of Mn, Ni, V, Co, Sb, and Cr.
