“…These results are consistent with those for Ricinus communis, Zea mays, and Calamagrostis villosa seedlings when they were cultured in high concentrations of nitrate and ammonia rather than in phosphorus (Vale et al, 1988;Peuke et al, 1994;Gloser and Gloser, 2000). Spalding and Goldsmith (1993) found that a light-induced increase in K + permeability of cell membrane was gained via ATP-activated channels, resulting in increased cytosolic concentration of K + .…”

“…Our Ca 2+ uptake rates (1À7 mmol g À1 dwt h À1 ) were slightly lower than loblolly pine trees in the field (8 mmol g À1 Lucash et al, 2007) and sycamore maple (Acer pseudoplatanus L.) seedlings in hydroponics (8 mmol g À1 dwt h À1 , Gloser and Gloser, 2000). Magnesium uptake rates (0:1À1:2 mmol g À1 dwt h À1 ) were similar to sycamore maple seedlings in hydroponics (0:2 mmol g À1 dwt h À1 , Gloser and Gloser, 2000) but lower than loblolly pine trees in the field Lucash et al, 2007). Uptake rates of K + were negative (À0:6 to À 3:2 mmol g À1 dwt h À1 ) and fell within the large range we found for loblolly pine trees in the field (À120 to 40 mmol g À1 dwt h À1 , Lucash et al, 2007).…”

“…Insignificant decrease of pH values were observed at the end of the experiments in the NH + 4 amended cultures in both the laboratory and field. This may be attributed to NH + 4 induction of chemical changes resulting in depression of essential cations such as K + , Ca 2+ , and Mg 2+ uptake (Gloser and Gloser, 2000). Although the uptake of many inorganic cations is reduced, the uptake of NH + 4 itself is high that plants generally take up an excess of cations relative to anions (Nocito et al, 2002;Spalding et al, 1999;Zhu et al, 2001).…”

Influences of phosphorus and nitrogen on uranium and arsenic accumulation in Lemna gibba L. were investigated in the laboratory hydroponic cultures and in the field pot experiments. The initial uranium and arsenic concentrations in solutions for the hydroponic cultures were 1000 µg l −1 each, while in situ trials used tailing water containing 198.7 ± 20.0 µg U l −1 and 75.0 ± 0.4 µg As l −1 at a former uranium mine in eastern Germany. A test of three PO 3− 4 concentrations (0.01, 13.6 and 40.0 mg l −1 ) in the hydroponic cultures, highest uranium accumulated in L. gibba under the culture with highest PO 3− 4 . Significant differences in uranium accumulation were between 0.01 mg l −1 and 13.6 mg l −1 PO 3− 4 cultures only (ANOVA p = 0.05). In the field, addition of 40.0 mg l −1 PO 3− 4 increased the bioaccumulation of uranium significantly. Contrary, high PO 3− 4 concentrations suppressed the bioaccumulation of arsenic in both the laboratory and the field. The bioaccumulation of both uranium and arsenic increased slightly with the increase of NH + 4 concentration. However, high NH + 4 concentrations reduced the yield in the control experiments. The concentration of uranium rose temporarily to 856.0 ± 294.0 µg l −1 , while the concentration of arsenic sunk slightly and temporarily immediately after amending the tailing waters with 40 mg l −1 PO 3− 4 . The speciation of uranium in the tailing water was modelled with geochemical code PhreeqC, which predicted that uranyl carbonate species dominated before addition of phosphates, but after increasing the PO 3− 4 concentrations, uranyl phosphates species became dominant. Addition of NH + 4 to the tailing water had negligible influence on free available uranium and arsenic concentrations. Thus, manipulations to enhance uranium and arsenic attenuation by L. gibba has limitation when the amendments interact with other elements including the contaminants in the milieu, and when the target contaminants have antagonistic behaviour in the tailing water.
