Structural group composition of dissolved organic matter in waters of thermokarst lakes of Bolshezemelskaya tundra
The relevance of the research is related to the intensive economic development of the Arctic part of the European North of Russia, which entails a sharp increase in anthropogenic pressure on vulnerable ecosystems of the Far North. At climate warming, melting of permafrost can provoke the formation of new thermokarst lakes and subsidence, which in its turn facilitates the removal of organic matter from peat into natural environments. The main aim is to reveal the features of composition of dissolved organic matter and its possible sources in the waters of thermokarst lakes of the Bolshezemelskaya tundra (near Naryan-Mar), with different water-mirror areas and at different stages of evolution. Methods. Analysis of the dissolved organic matter content in the waters of thermokarst lakes was carried out in the laboratory of georesources and the environment of Toulouse by the method of complete burning of dissolved organic carbon. In the laboratory of physicochemical methods of analysis of the Institute of Petroleum Chemistry of the SB RAS (Tomsk), by a three-step extraction at various pH the chloroformed concentrates were obtained. They contain dissolved organic matter. Organic structures were studied by Infrared spectroscopy. The structural-group composition of dissolved organic matter was determined by gas chromatography-mass spectrometry method.Β Results. Organic compounds in the waters of thermokarst lakes of Bolshezemelskaya tundra are mainly represented by hydrocarbons of aliphatic structure, carboxylic acid esters and aromatic compounds belonging to three homologous series. It was found, that low-molecular n-alkanes predominate in the small acid lake BZ-12, the main sources are bacteria, lower plants (unicellular algae) and phytoplankton. In the more mature and less acidic lake BZ-13, the main contribution belongs to higher terrestrial plants and coast marine algae. Phytoplankton also plays an important role in enriching water with dissolved organic matter. Accordingly, with evolution of the lake ecosy stem during recycling of a layer of peat sediments, the organic matters in waters are changed from the autochthonous to the allochthonnous
Elemental composition of macrophytes of thermokarst lakes in Western Siberia
Relevance. Macrophytes are one of the key participants in accumulation of chemical elements in lake ecosystems, but despite this, the issue of elemental composition of macrophytes of thermokarst lakes in Western Siberia and accumulation of chemical elements relative to the sediments and pore water remains practically unexplored. The aim of the research is to describe the formation of elemental composition of macrophyte species of thermokarst lakes in the north of Western Siberia and to identify the possibility of their use in biomonitoring. The objects of research were macrophyte plants (Hippuris vulgaris L., Glyceria maxima (Hartm.) Holmb., Comarum palustre L., Ranunculus spitzbergensis Hadac, Carex aquatilis Wahlenb s. Str., Menyanthes trifoliata L.), sediments and pore waters of thermokarst lakes of the north of Western Siberia. Methods. The elemental composition of the samples was studied by inductively coupled plasma mass spectrometry (ICP/MS, Agilent Technologies, 7500 se), the concentration of anions in water samples was determined by liquid chromatography (Dionex ICS/2000), the dissolved organic carbon was defined by infrared spectroscopy TOC/VCSN, Shimadzu), the organic carbon content of the sediments was determined by infrared spectrometry (Horiba Jobin Yvon Emia/320V C/S Analyzer). Statistical processing of data was carried out using the STATISTICA 6.0 software package. Results. The coefficients of biological accumulation of chemical elements in macrophytes relative to sediments and pore water were calculated for four key thermokarst lakes. It has been shown that macronutrients (Na, Mg, Ca), some heavy metals and metalloids (Ni, Cu, Zn, Co, As, Cd), as well as B and Mo are actively accumulated in water plants of thermokarst lakes of Western Siberia. High coefficients of accumulation of heavy metals indicate a significant phytoremediation function of macrophytes in a given territory

At climate warming, melting of permafrost can provoke the formation of new thermokarst lakes and subsidence, which in its turn facilitates the removal of organic matter from peat into natural environments. The main aim is to reveal the features of composition of dissolved organic matter and its possible sources in the waters of thermokarst lakes of the Bolshezemelskaya tundra (near Naryan-Mar), with different water-mirror areas and at different stages of evolution. Methods. Analysis of the dissolved organic matter content in the waters of thermokarst lakes was carried out in the laboratory of georesources and the environment of Toulouse by the method of complete burning of dissolved organic carbon. In the laboratory of physicochemical methods of analysis of the Institute of Petroleum Chemistry of the SB RAS (Tomsk), by a three-step extraction at various pH the chloroformed concentrates were obtained.

The structural-group composition of dissolved organic matter was determined by gas chromatography-mass spectrometry method. Results. Organic compounds in the waters of thermokarst lakes of Bolshezemelskaya tundra are mainly represented by hydrocarbons of aliphatic structure, carboxylic acid esters and aromatic compounds belonging to three homologous series. It was found, that low-molecular n-alkanes predominate in the small acid lake BZ-12, the main sources are bacteria, lower plants (unicellular algae) and phytoplankton.

Macrophytes are one of the key participants in accumulation of chemical elements in lake ecosystems, but despite this, the issue of elemental composition of macrophytes of thermokarst lakes in Western Siberia and accumulation of chemical elements relative to the sediments and pore water remains practically unexplored. The aim of the research is to describe the formation of elemental composition of macrophyte species of thermokarst lakes in the north of Western Siberia and to identify the possibility of their use in biomonitoring. The objects of research were macrophyte plants (Hippuris vulgaris L., Glyceria maxima (Hartm.) Holmb., Comarum palustre L., Ranunculus spitzbergensis Hadac, Carex aquatilis Wahlenb s. Str., Menyanthes trifoliata L.), sediments and pore waters of thermokarst lakes of the north of Western Siberia. Methods. The elemental composition of the samples was studied by inductively coupled plasma mass spectrometry (ICP/MS, Agilent Technologies, 7500 se), the concentration of anions in water samples was determined by liquid chromatography (Dionex ICS/2000), the dissolved organic carbon was defined by infrared spectroscopy TOC/VCSN, Shimadzu), the organic carbon content of the sediments was determined by infrared spectrometry (Horiba Jobin Yvon Emia/320V C/S Analyzer). Statistical processing of data was carried out using the STATISTICA 6.0 software package. Results. The coefficients of biological accumulation of chemical elements in macrophytes relative to sediments and pore water were calculated for four key thermokarst lakes. It has been shown that macronutrients (Na, Mg, Ca), some heavy metals and metalloids (Ni, Cu, Zn, Co, As, Cd), as well as B and Mo are actively accumulated in water plants of thermokarst lakes of Western Siberia. High coefficients of accumulation of heavy metals indicate a significant phytoremediation function of macrophytes in a given territory
