“…Deviation from the linearity assumption was also supported by our recent study on uptake of U, molybdenum (Mo), nickel (Ni), Pb and Zn in five forest plant species (blueberry, fern, may lily, rowan, spruce) growing at two boreal forest sites in Central Finland (Tuovinen et al, 2011). For all the elements and plant species studied, CRs were higher at low than at high soil concentrations (Tuovinen et al, 2011). In spite of these observations of non-linearity, use of linear CRs continues widely in radioecological modeling because they are easy to use and empirically determined values are readily available for many plant species.…”

“…However, non-linear transfer has been reported for many metals including essential elements such as calcium, magnesium, manganese (Vera Tome et al, 2003), zinc (Zn) and copper and for non essential elements such as lead (Pb), cadmium (Krauss et al, 2002) and mercury (Han et al, 2006), and for radionuclides of uranium (U), thorium (Th) and radium (Sheppard and Sheppard, 1985;Mortvedt, 1994). Deviation from the linearity assumption was also supported by our recent study on uptake of U, molybdenum (Mo), nickel (Ni), Pb and Zn in five forest plant species (blueberry, fern, may lily, rowan, spruce) growing at two boreal forest sites in Central Finland (Tuovinen et al, 2011). For all the elements and plant species studied, CRs were higher at low than at high soil concentrations (Tuovinen et al, 2011).…”

“…The ln-transformation also approximately linearised the non-linear dependence of CR values on soil concentration observed in a previous analysis (Tuovinen et al 2011). Adjusted coefficients of determination (R 2 adj ) taking into account sample size and the number of explanatory variables are reported.…”

Cobalt (Co), lead (Pb), molybdenum (Mo), nickel (Ni), uranium (U), and zinc (Zn) are among the elements that have radioactive isotopes in radioactive waste. Soil-to-plant transfer is a key process for possible adverse effects if these radionuclides are accidentally released into the environment. The present study aimed at investigating factors affecting such transfer in boreal forest. The plant species studied were blueberry (Vaccinium myrtillus), May lily (Maianthemum bifolium), narrow buckler fern (Dryopteris carthusiana), rowan (Sorbus aucuparia) and Norway spruce (Picea abies). Regression analyses were carried out to investigate the effects of the chemical composition and physical properties of soil on the soil-to-leaf/needle concentration ratios of Co, Mo, Ni, Pb, U and Zn. Soil potassium (K), magnesium (Mg), manganese (Mn), phosphorus (P) and sulphur (S) concentrations were the most important factors affecting the soil-to-plant transfer of the elements studied. Soil clay and organic matter contents were found to significantly affect plant uptake of Mo, Pb and U. Knowledge of the effects of these factors is helpful for interpretation of the predictions of radioecological models describing soil-to-plant transfer and for improving such models.

“…The key aspects of the increasing success of these green remediation technologies lie in the with a decrease in CRs with increasing soil concentrations. The use of non-linear functions to take into account this behavior has been proposed by several authors [17,18].…”

Applicability of a Freundlich-Like Model for Plant Uptake at an Industrial Contaminated Site with a High Variable Arsenic Concentration

Phytoextraction is a low-cost technology with negligible environmental impacts. A major issue at the field scale is the heterogeneity of contaminant concentration since the entire site needs to be treated evenly even though zones may need different incisiveness in the treatment. The concentration ratio (C shoot /C soil ) is generally used to evaluate plant species performance and it includes for simplicity an assumption of linearity in the uptake behavior, although deviation from linearity has been observed in several studies. This work describes a phytoextraction feasibility test, conducted at a greenhouse scale for the remediation of an arsenic-contaminated site. Since a feasibility test should also provide an uptake model that accounts for plant growth in heterogeneous areas, the investigation focused on defining the uptake behavior of the various selected species growing in a site with homogeneous soil properties, but with considerable differences in arsenic concentration. Among the many models selectable to describe the soil-to-plant transfer, the Freundlich-like approach was tested. While remaining easy to handle, the non-linear model selected proves to be adequate to predict the arsenic uptake despite the complex contamination considered, thus allowing a more realistic prediction of the potential of a field-scale phytoremediation procedure.
