Among 15 identified individual PAHs, the main contribution to their total amount was made by heavy highly condensed PAHs in the Eastern European peat plateaus, in particular, 6-nuclear benzoperylene (1021вЂ‰В±вЂ‰707В ng/g), whereas in West Siberian permafrost peatlands, light PAHs were dominating, mostly naphthalene and phenanthrene (211вЂ‰В±вЂ‰87 and 64вЂ‰В±вЂ‰25В ng/g, respectively). In the profile the qualitative and quantitative composition of PAHs was non-uniform estimated in a wide range: from 112 to 3673В ng/g with mean 1214вЂ‰В±вЂ‰794В ng/g.

The bogginess of the subarctic sectors of the European North-East and Western Siberia occupies a leading role in the climate regulation on the Earth.Personal Evaluation The strength of Genesis R&D is the database, which is an exceptionally complete and varied source of nutrient information. The nutrition information presented on this website is based on standard product formulations and was obtained through analysis by our nutritional software, entitled ESHA Genesis R&D, and information provided by our suppliers.Peatlands, occupying only 3% of the land surface, contain about 15вЂ“30% of global soil organic carbon reserves 1.

The presence of benzoperylene in the entire peat strata, including its permafrost layer, was a marker of the anaerobic conditions that persisted throughout the Holocene and they were necessary for the synthesis of this compound.Barnes & Nobles online bookstore for books, NOOK ebooks & magazines. In grass-dwarf shrub, grass-moss and moss peat, the share of 2-nuclear PAHs was most significant: naphthalene and fluorene, as well as 6-nuclear benzoperylene.

These markers were used to analyze soil organic carbon of permafrost peatlands in the tundra and forest-tundra, located in zones of continuous and massive island permafrost distribution 25, 26, 27, 28.However, these indicators cannot have a universal application due to the difference in species communities composing the peat, geochemical and landscape characteristics. To identify the plant groups that compose peat layers, the analysis of different chemical parameters is widely applied: the composition of humic substances and low molecular weight organic compoundsвЂ”aliphatic compounds, phenols, n-alkanes, alcohols, carbohydrates, low molecular weight organic acids 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24. Functional characteristics and indicators of the properties of peatlands were determined by using geochemical methods 9, 10, 11, 12, 13. This requires the understanding of what compounds are stored in permafrost.Along with traditional methods (plant macrofossil and palynological analyses of peat), qualitatively new geochemical methods and approaches are now widely used, showing the response of vulnerable Arctic and subarctic ecosystems to the climate change 8. Future permafrost thaw could lead to the release and inclusion of significant amounts of chemical elements and substances into geochemical flows 6, 7.

Polygonal peatland (TZвЂ”'Tazovsky': TZ 1, TZ 2 and TZ 3вЂ”67в‚0вЂІN, 78в…6вЂІE) was investigated in the subzone of the southern tundra in Western Siberia with polygonal-roller soil complexes. Two sites (TZ and K) are located in the southern tundra, the other two sites (Kh and I) are in the northern and extreme northern taiga, respectively. Thus, it is necessary to study the quantitative and qualitative PAH composition, especially in permafrost peat plateaus, conserving huge stocks of potentially labile organic carbon.There has been a high scientific interest in PAH study over the past decades 32, 33, 39, 40, 41, 42, 43, 44, 45, however, studies of the features of PAH accumulation in peatlands are extremely underrepresented 46, 47, 48, and in permafrost peatlands, they are singles 29, 49, 50.The purpose of this study was to assess the profile distribution of PAHs in permafrost peatlands in the East European and West Siberian permafrost zones.The objectives of the work are: (1) to compare of the PAHs profile distribution patterns in permafrost peatlands of different botanical composition (2) to identify of peat deposits having maximum PAH accumulation (3) to determine of trends in the accumulation of various PAH groups (4) to compare of PAH accumulation in permafrost peatlands of the East European and West Siberian plains.To study peat plateau/thermokarst complexes, we selected representative key sites located in similar permafrost peatlands. PAHs are characterized by high chemical stability, which, in combination with acidic and anaerobic cathotelm environment, does not result in PAH degradation. If organic matter in permafrost peat plateaus is conserved, it becomes vulnerable to mineralization during permafrost thaws. Peat is a product of biogenic accumulation, and a peat deposit is a chronicle pattern of changing flows of organic compounds, including PAHs of natural and anthropogenic origin 38.

Unlike palsas, the peat mounds have no isolated frozen cores, being the extensions of the permafrost peat plateau. These bare peat circles are round patches with a diameter of 4вЂ“25В m and areas from 10 to 500 m 2, covering up to 1вЂ“10% of the total peat plateau.The upheaved peat mounds (up to 2вЂ“3В m high) are drier than the peat circles and are sparsely vegetated. The soils of the peat circles (bare surfaces on permafrost peatlands) are identified as Ombric Sapric Cryic Histosols (Hyperorganic Turbic), because the upper horizons have signs of peat cryoturbation. Permafrost is absent or located deeper than 10В m in fens (the maximum depth of borehole drilling). The soils of the cracks are classified as Hemic Muusic Histosols, where the moderately decomposed peat accumulates on the polygonal-veined ice filling the cracks soils of seasonally freezing fens belong to Hemic Histosols. According to the WRB 52, the soils of polygons and peat plateaus are classified as Ombric Sapric Cryic Histosols (Hyperorganic), which characteristic diagnostic features are the presence of well-decomposed organogenic material (peat) down to more than 2В m deep, predominantly atmospheric nutrition and the underlying permafrost within 1В m.

Uliginosum L., Empetrum hermaphroditum L., Rubus schamaemorus L., Bryidae mosses ( Dicranum, Polytricum) and lichens (mainly representatives of the genus Cladonia). The main part of mounds and polygons is vegetated with polydominant shrub-lichen communities, e.g., Betula nana L., Ledum palustre L., Vaccinium vitis-idaea L., V. The polygonal peatland is almost flat from the surface, the excess of polygons over depressions (cracks) is up to 0.5В m.

Compactum, etc.Thus, the study area covers a vast part of the cryolithozone: from the Tazovsky site with a predominantly continuous permafrost 250вЂ“450В m thick and a shallow active layer (<вЂ‰0. The ground layer is covered by Sphagnum fuscum, S. The herb-dwarf shrub vegetation is dominated by Betula nana and Eriophorum media, as well as Rubus chamaemorus, Oxycoccus microcarpus.
