“…In fact, as Massas et al (2002) have underlined, pot-derived data of caesium plant uptake compared to field data usually lead to higher TF values due to differences in environmental and root conditions. Anyhow, our transfer factors for 137 Cs are in agreement with results reported by Grytsyuk et al (2006) for grassy coenoses, while for 60 Co are one order of magnitude higher than those presented by Rahman et al (2007) for grassy vegetation in tropical environment and within the range of values reported by IAEA (1994) for mixed green vegetables. The present results are, also, in agreement with estimations of previous experiments from our team (Sabbarese et al, 2002c).…”

“…Various and numerous ecological variables affect the radionuclides transfer from soil to plants; in particular, the vegetable species, the kind of radionuclide and its chemical-physical characteristics, the pedological properties, the presence and the kind of mycorrhizal symbiosis (Berreck and Haselwandter, 2001). Grytsyuk et al (2006) have studied the dependence of 137 Cs TF from soil characteristics, like texture, granulometry, gleyization and moisture, under natural conditions, showing a variation of 137 Cs uptake over more than one order of magnitude. Tsukada and Nakamura (1999) have shown that the TF of Cs isotopes is negatively correlated with K concentration in the soil.…”

“…For example, uptake of radioactive Cs by plants was increased by an increase in soil nitrogen (N) content and a decrease in potassium (K) content (Evans and Dekker 1969;Belli et al 1995). Soil organic matter content also increases radioactive Cs uptake by plants (van Bergeijk et al 1992;Absalom et al 1996;Sanchez et al 1999;Grytsyuk et al 2006;Tulina et al 2010), due to the lack of sufficient clay minerals to fix radioactive Cs (Rigol et al 2002). These studies suggest that pasture management, such as fertilization and usage (e.g., herbivore grazing, cutting), affects soilto-plant transfer of radioactive Cs.…”

“…Many studies have shown that plant uptake of radioactive Cs is higher from soil rich in organic matter (van Bergeijk et al 1992;Absalom et al 1996;Sanchez et al 1999;Grytsyuk et al 2006); this is because organic matter decreases the affinity of clay for Cs, which increases Cs mobility (Dumat et al 1997;Sanchez et al 1999;Staunton et al 2002). The soil used in our study was an Andosol, which is rich in organic matter (Nanzyo 2002).…”

The accident at Fukushima Dai-Ichi Nuclear Power Station (NPS) extensively contaminated the agricultural land in the Tohoku region of Japan with radioactive cesium [sum of cesium-134 ( 134 Cs) and cesium-137 ( 137 Cs)]. We evaluated the status of radioactive cesium (Cs) contamination in soil and plants at the Field Science Center of Tohoku University, northern Miyagi prefecture, 150 km north of the NPS. In seven pastures with different management, we examined: (1) the distribution of radioactive Cs in soil, (2) the concentration of radioactive Cs in various herbaceous plant species and (3) the change in radioactive Cs content of plants as they matured. We collected samples of litter, root mat layer (root mat soil and plant roots), and subsurface soil (0-5 cm beneath the root mat) at two to three locations in each pasture in December 2011 and May 2012. The aboveground parts of herbaceous plants (four grasses, two legumes, and one forb species) were collected from May 9 to June 20, 2012, at 14-d intervals, from one to five fixed sampling locations in each pasture. The distribution of radioactive Cs in soil differed among pastures to some degree: a large proportion of radioactive Cs was distributed in the root mat layer. Pasture management greatly influenced the radioactive Cs content of herbaceous plants (p < 0.001); plant species had less influence. Radioactive Cs content was highest (> 3 kBq kg −1 dry weight) on May 9 and significantly decreased with maturity (p < 0.001) for most of the pastures, whereas it remained low (0.04-0.18 kBq kg −1 dry weight) throughout the measurement period in the pasture where composted cattle manure was applied. The soil-to-plant transfer factor was negatively correlated to pH(H 2 O) (R 2 = 0.783, p < 0.001) and exchangeable K content (R 2 = 0.971, p < 0.001) of root mat soils, which suggests that surface application of composted cattle manure reduces plant uptake of radioactive Cs by increasing the exchangeable K content of the soil. The radioactive Cs content of plants decreased with plant maturity; its degree of decrease (May 9 to June 6) was smaller in legumes (80.6%) than grasses (55.5%) and the forb (58.6%). Radioactive Cs content decreased with plant maturity; also, the proportion remaining in the aboveground plant was higher in legumes (80.6%) than grasses (55.5%) and the forb (58.6%).

“…Its mobility and thus its migration rate can be decreased by increased contents in clay fraction, organic matter and Fe and Mn contents (Arapis et al, 1997). Moreover, the soil organic matter, and especially this characterized by high molecular weight, is likely to accumulate a large proportion of 137 Cs and therefore it influences its relative low mobility (Grytsyuk et al, 2006).…”

Τα βρύα αποτελούν ιδανικούς βιοϊχνηθέτες. Δε διαθέτουν ριζικό σύστημα, οπότε όλα τα θρεπτικά συστατικά καθώς και το νερό που χρειάζονται τα παίρνουν κατευθείαν από την υγρή και ξηρή εναπόθεση. Από το 1990 και κάθε 5 χρόνια διεξάγεται μια Ευρωπαϊκή έρευνα στο πλαίσιο του ICP Vegetation Programme σε σχέση με τις συγκεντρώσεις των ιχνοστοιχείων σε φυσικά αναπτυσσόμενα βρύα. Η τελευταία έρευνα πραγματοποιήθηκε το 2015/2016, στην οποία η Ελλάδα συμμετείχε για πρώτη φορά με την ομάδα μας. Στα μέσα του καλοκαιριού του 2016, ενενήντα πέντε (95) δείγματα βρύων Hypnum cupressiforme Hedw. συλλέχθησαν από την περιοχή της Βορείου Ελλάδος. Αφού καθαρίστηκαν, προετοιμάστηκαν για τη μέτρησή τους με τη μέθοδο της Νετρονικής Ενεργοποίησης και της γαμμα- φασματοσκοπίας, για τον προσδιορισμό των συγκεντρώσεων των ιχνοστοιχείων και των ραδιονουκλιδίων αντίστοιχα. Μετρήθηκαν οι συγκεντρώσεις 44 ιχνοστοιχείων (Al, As, Ni, V, Cr, Zn, Fe, Br, Cl, I, Mg, Na, K, Sc, Ti, Mn, Co, Se, Rb, Sb, Au, Th, U, Si, Sr, Ca, Zr, Cs, Ba, La, Ce, Nd, Sm, Gd, Tb, Dy, Tm, Yb, Lu, Hf, Ta, In, Mo, Ag). Για τον προσδιορισμό των πηγών τους, εφαρμόστηκε το μοντέλο PMF5, σύμφωνα με το οποίο αναγνωρίστηκαν 5 πηγές: η σκόνη από το χώμα, το παλαιωμένο θαλασσινό αλάτι, η σκόνη από τον δρόμο, τα εργοστάσια καύσης λιγνίτη και τέλος η πλούσια σε Mn πηγή. Η σκόνη από το χώμα συνεισφέρει στα περισσότερα δείγματα των βρύων σε ποσοστό πάνω από 50%, υποδεικνύοντας ότι η πλειοψηφία των ιχνοστοιχείων μεταφέρεται στα βρύα μέσω της επαναιώρησης του χώματος. Μελετήθηκαν ακόμη οι συγκεντρώσεις των εξής ραδιονουκλιδίων: 7Be, 210Pbuns, 40K, 232Th, 226Ra και 137Cs. Παρατηρούνται μικρές διαφορές στις συγκεντρώσεις τους, ανάλογα με την επιφάνεια συλλογής των βρύων (πάνω από πέτρες, στο έδαφος, σε κλαδιά και κοντά στις ρίζες). Το 7Be παρουσιάζει μεγαλύτερες συγκεντρώσεις στα δείγματα που συλλέχθησαν από το έδαφος από ότι κοντά στις ρίζες, ενώ το 40K, εμφανίζει μεγαλύτερες συγκεντρώσεις στα βρύα που βρίσκονταν κοντά στις ρίζες. Όσον αφορά τα δείγματα χώματος που συλλέχθησαν από τις ίδιες περιοχές με τα βρύα, υπάρχει μια ταύτιση μεταξύ των περιοχών που παρουσιάζουν υψηλές συγκεντρώσεις 137Cs στα βρύα, στα χώματα και αυτών που είχαν χαρακτηριστεί ως οι πιο επιβαρυμένες ακριβώς μετά το ατύχημα στο Τσέρνομπιλ. Τελος, η επαναιώρηση του χώματος είναι η κύρια πηγή της πλειοψηφίας των ιχνοστοιχείων και των ραδιονουκλιδίων στα βρύα.
