“…The plant material of the STL peat is dominated by green and sphagnum mosses, subshrubs, and vascular plants. Numerous studies indicate the use of bryophytes as bioindicators of atmospheric metal deposition, since they mainly absorb elements from the atmosphere [58,59]. Mosses can accumulate metals in excess of their physiological needs for the morphological structure of cells and tissues [60].…”

One of the main reservoirs depositing various classes of pollutants in high latitude regions are wetland ecosystems. Climate warming trends result in the degradation of permafrost in cryolitic peatlands, which exposes the hydrological network to risks of heavy metal (HM) ingress and its subsequent migration to the Arctic Ocean basin. The objectives included: (1) carrying out a quantitative analysis of the content of HMs and As across the profile of Histosols in background and technogenic landscapes of the Subarctic region, (2) evaluating the contribution of the anthropogenic impact to the accumulation of trace elements in the seasonally thawed layer (STL) of peat deposits, (3) discovering the effect of biogeochemical barriers on the vertical distribution of HMs and As. The analyses of elements were conducted by atom emission spectroscopy with inductively coupled plasma, atomic absorption spectroscopy and scanning electron microscopy with an energy-dispersive X-ray detecting. The study focused on the characteristics of the layer-by-layer accumulation of HMs and As in hummocky peatlands of the extreme northern taiga. It revealed the upper level of microelement accumulation to be associated with the STL as a result of aerogenic pollution. Specifically composed spheroidal microparticles found in the upper layer of peat may serve as indicators of the area polluted by power plants. The accumulation of water-soluble forms of most of the pollutants studied on the upper boundary of the permafrost layer (PL) is explained by the high mobility of elements in an acidic environment. In the STL, humic acids act as a significant sorption geochemical barrier for elements with a high stability constant value. In the PL, the accumulation of pollutants is associated with their sorption on aluminum-iron complexes and interaction with the sulfide barrier. A significant contribution of biogenic element accumulation was shown by statistical analysis.

“…Occasionally, raw concentrations were normalised to the Earth's crustal abundance pattern or the soil by calculating the enrichment factor. This helped to account for uctuations in absolute levels and gave an indication of the elements' sources(Ma et al 2020, Taeprayoon et al 2023). The following is a mathematical expression or from very strong secondary branches.…”

E. julaceum is one of the species of corticolous mosses which is distributed widely in Upper Assam which falls under Tropical Rain Forest and Eastern Himalayan Biodiversity Hot Spot. Upper Assam is the most productive region in the state of Assam, with abundant natural resources such as coal, oil, and natural gas in addition to tea plantations. Concentration of five heavy metals viz., Cd, Cu, Ni, Cr and Pb were determined by ICP-OES analysis in the moss species along with its BAF and EF for each metal. It has revealed from the study that the species has significant concentrations of Cr, Cu, and Pb in all the study sites. The study unequivocally shows that species are capable of accumulating Cr, Cu, and Pb, and that they may thrive in industrial environments by creating dense carpets in the phorophytes.
