“…As cement dust, soils and pines growing in the vicinity of the cement plant contain Ca in high concentrations (Mandre et al 2008;Mandre 2009;Ots 2002) it can be to hypothesised that Ca may decrease the uptake, accumulation and translocation of Cd in the crown of pine. The same opinion is held by Österås and Greger (2003), who in their research proved that Ca reduces the accumulation of Cd in tissues of Norway spruce. Recently, Suzuki (2005) showed also that Ca reduced the uptake and toxic effect of Cd in Arabidopsis, Choi et al (2001) in tobacco plants and Rivetta et al (1997) in radish.…”

The concentration of heavy metals in soil and in Scots pine (Pinus sylvestris) organs growing on a pH gradient from 4.0 to 7.9 of soil at different distances from a cement plant was monitored. Emission for over 40 years of alkaline dust (pH 12.3-12.6) into the atmosphere in North Estonia had resulted in alkalisation and elevated concentration of total heavy metals in upper layers of the soil (0-30 cm), which was considerable even 10 years after the dust pollution stopped. Monitoring showed that the accumulation and allocation of heavy metals varied between the stem, shoots and needles and differed from the trees in the unpolluted area, depending more on the mobility of elements and the pH than element concentrations in the alkaline soil. A strong negative correlation was found between the soil pH and Mn, Zn and Cd concentrations in different tree organs. Compared to the unpolluted area, Pb was present in relatively higher concentrations in all organs but Cr, Fe and Cu in needles and shoots. The concentrations of Mn and Cd were much lower than control in all organs of trees in alkalised soil. The height increment and density of needles on shoots were predominantly in negative correlation with the pH of soil.

“…An increase of Ca concentration under Cd stress would be a possible mechanism for reducing toxic effects of Cd, and a decrease of Ca concentration under Cd toxicity may be a symptom of a damaged intercellular defence system. Osteras and Greger (2003) have also found interaction between heavy metals and calcium, which explained the observed concentrations of metals in bark and wood. As a whole, in such a carbonate environment, even Fig.…”

a b s t r a c tVicia faba L. seeds were grown in a pot experiment on soil, mine tailings, and a mixture of both to mimic field situations in cultivated contaminated areas near mining sites. Metals in the substrates and their translocation in root, stem and leaf tissues were investigated, including morphological responses of plants growing on mine tailings. Metal concentration -and generally bioaccumulation -was in the order: roots > leaves > stems, except Pb and Cd. Translocation was most significant for Zn and Cd, but limited for Pb. Metal concentration in root and leaf was not proportional to that in the substrates, unexpectedly the minimum being observed in the mixed substrate whilst plant growth was retarded by 20% (38% on tailings). Calcium, pH, organic matter and phosphorus were the main influencing factors for metal translocation. The ultrastructure of V. faba L. cells changed a lot in the mine tailings group: root cell walls were thickened with electron dense Pb, Zn and C particles; in chloroplasts, the number of plastoglobuli increased, whereas the thylakoids were swollen and their number decreased in grana. Finally, needleshaped crystalline concretions made of Ca and P, with Zn content, were formed in the apoplast of the plants. The stratagems of V. faba L. undergoing high concentrations of toxic metals in carbonate substrate, suggest root cell wall thickening to decrease uptake of toxic metals, a possible control of metal transport from roots to leaves by synthesizing phytochelators-toxic metal complexes, and finally a control of exceeded Ca and metal concentration in leaves by crystal P formation as ultimate response to stress defense. The geochemical factors influencing metal availability, guaranty a reduction of metal content in plant growing on mixed tailing/soil substrate as far as carbon te are not completely dissolved.

“…For the ash+GLD treatment, the reduced Cd content is probably mainly caused by an increased bioavailability of competing ions like Ca (Table I and Figure 1B). Elevated Ca addition has been shown to decrease the Cd content of bark in young Norway spruce (Österås and Greger, 2003). Further, the affinity of Ca to cell walls ought to be higher than Cd, since the affinity of Cd to cell walls has been found to be similar to Zn (Williams and Rayson, 2003).…”

“…Thirteen years after application of 20 000 kg ha −1 of wood bark ash on a peatland field the K, B and Zn concentrations were increased in needles of Scots pine growing on the field (Ferm et al, 1992). Elevated levels of Ca, Cd, Cu or Zn, comparable to wood ash application, have been shown to increase the contents of Ca, Cu and Zn, but not Cd, in wood and/or bark of young Norway spruce (Österås and Greger, 2003).…”

“…Field studies with wood ash have shown that wood ash application can increase the concentration of Ca as well as heavy metals, such as Cd, Cu and Zn, in the forest soil solution (Bramryd and Fransman, 1995;Rumpf et al, 2001;Arvidsson and Lundkvist, 2003). Elevated concentrations and changed proportions of metals due to wood ash application will probably be reflected in wood and bark of forest trees (Österås and Greger, 2003).…”

To counteract nutrient depletion and acidification of forest soils, recycling of waste products from the forest industry has been suggested. Spreading of these waste products will probably change the concentration and availability of Ca and heavy metals in forest soils and thereby the contents of these metals in trees. This field study aimed at examining the influence of pellets of wood ash (ash) or a mixture of wood ash and green liquor dregs (ash+GLD) on the contents of Ca, Cd, Cu and Zn in wood and bark of Norway spruce [Picea abies (L.) Karst.]. The waste products were spread in an amount of 3000 kg ha −1 in 1996 at a felling site in Sweden and in 1999 and 2002 young spruce trees, planted in 1995, were collected and wood and bark were analysed for Ca, Cd, Cu and Zn with AAS. Changes in the metal content of wood and bark of young spruce trees were found 3 and 6 years after spreading pellets of ash or ash+GLD compared with the control. The effect of the treatments on the metal contents of bark and wood differed and was larger after 3 years than after 6 years. Treatment with ash+GLD tended to have less effect on the metal contents of bark and wood than treatment with only ash. An increase in the contents of Cu and Zn in bark or wood, compared with the control, was only found for the ash treatment and only 3 years after application. Both the ash and ash+GLD treatment decreased the Cd content of the wood and/or bark after 3 years, and after 6 years it still was, or tended to be, lower than the control.
