“…This side-effect of liming should be carefully taken into account when decisionmakers seek countermeasures against the contamination of rice fields with radiostrontium. Kliashtorin et al (1994) concluded from their experimental results that 90 Sr could comparatively easily reach the underground water table. Table 4 gives the depth distribution of the activity in the top 20 cm of the soil after rice harvest in experiment I.…”

“…It is well known that radiostrontium moves faster down the soil profile than radiocesium (Cline and Rickard, 1972;Kliashtorin et al, 1994;Salbu et al, 1994;Askbrant et al, 1996). Many works (Livens et al, 1991;Salbu et al, 1994;Askbrant al., 1996) have been reported to show the localization of radiocesium with respect to the soil surface in the Chernobyl-affected areas even years after the accident.…”

“…90 Sr is amongst the most radioecologically significant isotopes released into terrestrial ecosystems (Kliashtorin et al, 1994). It is a chemical analogue of Ca which is accumulated by microbes, plants and animals to fulfil essential physiological functions .…”

“…The 28.8 year half-life and high energy ␤-emissions of 90 Sr mean that it can be a significant long-term radiological hazard to the biosphere. 90 Sr is available to the soil solution in almost any mineral soil it contaminates (Frissel, 1992), transport is rapid (Kliashtorin et al, 1994), and transfer to plants high (Ban-nai and Muramatsu, 2002). In the Khyshtym accident zone 90 Sr is the most common contaminating radioisotope (Karavaeva et al, 1994;Tikhomirov and Shcheglov, 1994) and in the Chernobyl exclusion zone 90 Sr is a significant contributor to * Corresponding author.…”

A Residual Maximum Likelihood (REML) procedure was used to compile Sr concentrations in 103 plant species from experiments with Sr concentrations in 66 plant species from the literature. There were 14 species in common between experiments and the literature. The REML procedure log e -transformed data and removed absolute differences in Sr concentrations arising from soil factors and exposure times to estimate mean relative Sr concentrations for 155 species. One hundred and forty-two species formed a group with a normal frequency distribution in mean relative Sr concentration. A nested hierarchical analysis of variance (ANOVA) based on the most recent molecular phylogeny of the angiosperms showed that plant species do not behave independently for Sr concentration but that there is a significant phylogenetic effect on mean relative Sr concentrations. Concentrations of Sr in non-Eudicots were significantly less than in Eudicots and there were significant effects on Sr concentrations in the dataset down the phylogenetic hierarchy to the family level. Of the orders in the dataset the Cucurbitales, Lamiales, Saxifragales and Ranunculales had particularly high Sr concentrations and the Liliales, Poales, Myrtales and Fabales particularly low Sr concentrations. Mean relative Sr concentrations in 60 plant species correlated with those reported elsewhere for Ca in the same species, and the frequency distribution and some phylogenetic effects on Sr concentration in plants were similar to those reported for Ca. This analysis of mean relative Sr concentrations in 155 plant species across the angiosperm phylogeny might be helpful for modelling 90 Sr in food chains, predicting radiological doses to flora, and selecting species for phytomonitoring and phytoremediation of 90 Sr.

“…An increased water percolation in the flooded rice field would accelerate the downward movement of 90 Sr and, in turn, its loss from the topsoil (Cline and Rickard, 1972;Kliashtorin et al, 1994;Kwaratskhelia et al, 1967).…”
