“…In addition to this, nonessential elements like Zr, Th, and U and toxic elements including the heavy metals Al, Sb, As, Cs, and Pb also increased in concentrations as decomposition proceeded. Increase in the concentration of these elements agrees with other studies done in Scandinavian ecosystems (Laskowski and Berg, 1993;Brun et al, 2008) and elsewhere (Yue et al, 2019;Li et al, 2020;Kondratova and Bryanin 2021;De Marco et al, 2022). Their increase in concentrations probably is related with increased AUR and N, since we observed significant relationship between them (Fig.…”

“…Work on understanding the dynamics of some of the elements in this group, namely heavy metals, started as early as in the 1970's (Rühling and Tyler, 1973) and was later followed by crucial studies giving rare views of their dynamics (Fe, Mn, Zn, Cu, Al, Co, Mo, Ti, V, Zn, Cd, Pb, Ni, Cr, and REEs) tied to litter decomposition (Laskowski and Berg, 1993;Yue et al, 2019;Montemagno et al, 2021;De Marco et al, 2022;Kondratova and Bryanin 2021). Still, for most of the ecosystems, for reasons unknown, such studies have not been prioritized for several other trace elements and REEs (Berg and Laskowski, 2005;Brun et al, 2008;Cao et al, 2018;Gautam et al, 2019).…”

The temporal dynamics of 33 major, trace and rare earth elements (REEs) was studied in the Swedish Norway spruce-NSL (Picea abies) and Scots pine-SPL (Pinus sylvestris) litters with the aim to assess their release and accumulation dynamics. Litter bags (8×8cm) were incubated in paired monoculture stands of both the species for upto five years from 1979-1984 according to a randomized block design comprising 25 blocks (1×1 m) within an area of 625 m2. Decomposition rate was slightly higher for SPL (k = 0.315) compared to that of NSL (k= 0.217). During litter decomposition, until ~70% accumulated mass loss (AML), concentration of trace elements increased >50% in both litter types relative to initial concentrations. The pattern of concentration change was non-linear, and polynomial quadratic regression between concentration change and AML resulted in a significant relationships (adj R2= 0.20–0.97; P = 0.15–<0.0001). The changes in concentration and amount of trace elements resulted in two main types of dynamics; (i) both concentration and amount increased for Fe, Al, Ti, Cu, Mo, V, Zr, Sb, As, Cs, Pb, Th and U; (ii) concentration increased but amount decreased for Ni, Zn, Li and Sr. REEs’ amounts increased ~3-fold to 99-fold between the beginning and end of incubations suggesting accumulation during litter decomposition. Dynamics of different REEs were similar in their patterns of change in the two litters. Different REEs, had generally identical patterns of change during incubation, which is reflected in the high correlations among them (r2 = >0.95). A general upward convexity in the dynamics hints that if further incubated in the field, decomposing litter could have accumulated more REE in the organic matter. The results of this study can be useful for future studies in other ecosystems including metal-contaminated sites or element depleted sites. Plant litter accumulation, its decomposition and build-up of humic substances in the decomposing organic matter can act as sink for elements and can be used as a management tool for ecological amelioration of metal-contaminated sites as well as natural systems that are impoverished, especially recuperating ones. The study's findings have implications beyond such sites and can be useful in any research that seeks to understand the patterns of accumulation and release related to decomposition in different ecosystems.

“…The main aspects of heavy metals' behavior during forest fires in the studied area are passive accumulation in the fire plot, redeposition on the leeward side of the fire with the enrichment of all components of the forest ecosystem, and possibly long-distance atmospheric transfer [81,82]. The organic horizons of higher thickness in the control plot also have an ability to accumulate elements compared to lower horizons, but not as much as in the postfire plot.…”

Data on the main properties of Histic Podzols in the pine forests of semi-hydromorphic landscapes in the middle taiga of the Komi Republic after forest fires are presented. A decrease in topsoil horizon thickness by more than 7.6 times, an increase in litter density by 6 times, and a decrease in litter stock by 4 times were observed in postfire soil. There was an increase in carbon content in the pyrogenic horizon (48%) and in the upper part of the podzolic horizon—from 0.49 at the control plot to 1.16% after the fire. The accumulation of all studied trace metals (Cu—from 2.5 to 6.8 mg × kg−1; Zn—from 35.7 to 127.4 mg × kg−1; Ni—from 2.2 to 8.1 mg × kg−1; Pb—from 1.4 to 28.3 mg × kg−1; Cd—from 0.3 to 1.1 mg × kg−1) in soils after wildfires was recorded. The effect of the fire can be traced to a depth of approximately 20–30 cm. A significant influence of the pyrogenic factor on the alpha and beta bacterial diversity was noted. The bacterial response to a forest fire can be divided into an increased proportion of spore-forming and Gram-negative species with complex metabolism as well.

The temporal dynamics of 33 major, trace, and rare earth elements (REEs) were studied in the litter samples containing Swedish Norway spruce (Picea abies) (NSL) and Scots pine (Pinus sylvestris) (SPL), with the aim to assess their release and accumulation dynamics. Litter bags (8 × 8 cm) were incubated in paired monoculture stands with both the species for up to 5 years from 1979 to 1984 according to a randomized block design comprising 25 blocks (1 × 1 m) within an area of 625 m2. The decomposition rate was slightly higher for Scots pine litter (k = 0.315) than for Norway spruce litter (k = 0.217). During litter decomposition, at ∼70% accumulated mass loss (AML), the concentration of trace elements increased by >50% in both litter types compared to initial concentrations. The concentration change took place in a non-linear pattern, and polynomial quadratic regression between concentration change and accumulated mass loss resulted in significant relationships (adj R2 = 0.20–0.97; p = 0.15–<0.0001). The changes in concentration and amount of trace elements resulted in two main types of dynamics: 1) both concentration and amount increased for Fe, Al, Ti, Cu, Mo, V, Zr, Sb, As, Cs, Pb, Th, and U; 2) concentration increased but amount decreased for Ni, Zn, Li, and Sr. The amount of REEs increased from ∼3-fold to 99-fold from the beginning to the end of incubation, suggesting accumulation during litter decomposition.
