“…The initial Zn concentrations were as high as 250 and 218 μg g -1 in -B and +B, respectively, and the Mn levels were also very high. Silver birch is known to have high capacity for Zn accumulation (Kopponen et al 2001, HagenThorn andStjernquist 2005), and Mn accumulation is known in Betula pubescens (Reimann et al 2007). Both Zn and Mn, as well as Ca, Cd, Cu, Fe and Mg concentrations were lower in the B litter +.…”

“…The accumulation of Al, Fe, Na and Pb may have been partly caused by a difference between the uptake of these elements from the nutrient solution and peaty growth medium in the pots, compared to the amounts encountered in the soil in the incubation site. Geogenic and anthropogenic dust is a significant source of metals, which then accumulate on surfaces of plants and litter in the field (Tyler 2005, Reimann et al 2007). However, increases have been found in Al and Fe (Palviainen et al 2004b) and Pb, as well as Zn and Cu also in native conifer and beech litter (Berg and McClaugherty 2003, Brun et al 2008, Tyler 2005.…”

Inadequate boron (B) nutrition can affect the structural integrity and chemical composition of plant tissues. The changes in mass and element concentrations were studied using silver birch (Betula pendula Roth) leaf litter from seedlings grown with or without added B (B litter + or B litter −). The litter was produced in a growth room, and it was incubated in either B fertilised or control forest plots (B soil + or B soil −) between the moss and humus layers in two Norway spruce stands for 13 months. Additionally, the field decomposition experiment included longterm N and P application treatments (N soil and P soil ). B litter + somewhat reduced the remaining litter mass. In contrast, B soil + increased it, possibly because of lower soil pH. The +N soil treatment reduced the remaining mass. B litter + increased the remaining P, S, Cu, Cd, Ni and Zn but reduced Pb. Remaining B was high in the B litter -which also accumulated B from soil. B soil increased remaining Ca, Cd, Mg, Na, Pb, and slightly reduced N (in N fertilised plots). These changes in decomposition and element release have a potential to affect nutrient, carbon, and heavymetal cycles in areas where B deficiencies are common, and where B fertilisation is practised.

“…Bedrock lithology, ore 53 occurrences and urban contamination all have an influence on the element concentrations in 54 soils and consequently in plants (e.g. Reimann et al, 2007a). Over the last few decades much 55 attention has been paid towards soil pollution involving excess levels of both the essential 56 micronutrients and some of the non-essential, potentially-toxic trace elements such as Cd and 57…”

We investigated the effect of organic matter and weathering on the lability and solid phase speciation of heavy metals (Cd, Cr, Cu, Ni, Pb, Zn) in two contrasting subalpine regions in the Italian Alps. Cr, Ni and Cu could be linked to weathering. This was not the case for Pb. Since organic matter (OM) influences the solid phase speciation of heavy metals, the total organic C and N content, the C and N content of different density fractions of OM and also of the labile (oxidised by H2O2) and stable (H2O2-resistant) fractions were determined. Soil OM stocks were high and soils on north-facing slopes had more OM than the south-facing sites to which they were paired. Density measurements and the H2O2 fractionation indicated that the higher OM content on north-facing sites was due to an accumulation of weakly degraded organic material. Due to higher weathering intensity on north-facing sites, the abundance of the EDTA-extractable heavy metals was higher than on south-facing sites. All EDTA-extractable heavy metals showed a good correlation to the water-soluble phenolic concentrations which indicates that the metals were probably translocated as metalorganic complexes. Pb and Cu correlate not only to the light (density b1 g/cm3) and labile, organic fraction but also to the heavy (densityN2g/cm3) and stable fraction. High-mountain ecosystems like the Alps are sensitive to changing environmental conditions such as global warming. A warmer climate and the more favourable conditions it brings for biological activity, especially at cooler sites, will probably lead in the short-to mid-term to an increased loss of accumulated, weakly degraded OM. As the Pb and Cu content is significantly related to the labile organic matter pools, the risk exists that an increase in OM mineralisation could affect the storage capacity and mobility of these metals in soils. Abstract 24We investigated the effect of organic matter and weathering on the lability and solid phase 25 speciation of heavy metals (Cd, Cr, Cu, Ni, Pb, Zn) in two contrasting subalpine regions in 26 the Italian Alps. Cr, Ni and Cu could be linked to weathering. This was not the case for Pb. 27Since organic matter (OM) influences the solid phase speciation of heavy metals, the total 28 organic C and N content, the C and N content of different density fractions of OM and also of 29 the labile (oxidised by H 2 O 2 ) and stable (H 2 O 2 -resistant) fractions were determined. Soil OM 30 stocks were high and soils on north-facing slopes had more OM than the south-facing sites to 31 which they were paired. Density measurements and the H 2 O 2 fractionation indicated that the 32 higher OM content on north-facing sites was due to an accumulation of weakly degraded 33 organic material. Due to higher weathering intensity on north-facing sites, the abundance of 34 the EDTA-extractable heavy metals was higher than on south-facing sites.

“…Birch uses its leaves for detoxification of the plant, and very little Pb from Pb uptake from soil reaches the bark (Reimann et al, 2007c). This natural process (Goldschmidt's plant pump -Goldschmidt, 1937), and not contamination, is at the same time the starting point of the strong enrichment of Pb that is observed in the O-horizon.…”

“…None of the other materials provided such a clear urban contamination signal (Reimann et al 2007a-c). Terrestrial moss did not show, for example, any Hg indication, while birch bark did (Reimann et al, 2007c). Many of the materials reveal only single site anomalies for most of the elements studied, and interpretation requires intimate knowledge of local conditions and possible element sources.…”
