Abstract— The composition and content of hydrocarbons (HCs) in the waters three raised bogs of the south taiga subzone of Western Siberia: the Bolshoe bog, Central bog, and Bakchar bog (which is part of the Great Vasyugan mire) were determined by IR spectrometry, fluorimetry, and chromatography–mass spectrometry. The waters of the bogs are demonstrated to contain hydrocarbons coming from peat deposits (and produced by plants) and pyrogenic hydrocarbons. The Bolshoe bog, which occurs near areas with oil-producing facilities, is the only one whose water contains oil hydrocarbons. The most representative HCs group is n -alkanes whose carbon preference index (CPI) is 4.9–9.2. Among alicyclic HCs, the highest concentrations were detected for triterpenes, with the dominance of taraxerene and neohop-13(18)-ene in the Bolshoe and Bakchar bogs and diploptene in the Central bog. Contamination with oil hydrocarbons, which are transferred by air from oil- and gas-producing facilities, was identified based on the presence of methyl-substituted polycyclic aromatic hydrocarbons (PAHs), steranes, hopanes, and cheilanthanes and by reduced CPI in the water of the Bolshoe bog. The effect of fires in 2016 is inferred from the ratios of unsubstituted PAHs.

西西伯利亚南部针叶林凸起沼泽水域中碳氢化合物的鉴定

摘要：采用红外光谱法测定了西西伯利亚南部针叶林亚带三个凸起沼泽：Bolshoe 沼泽、Central 沼泽和 Bakchar 沼泽（属于 Great Vasyugan 泥沼）中的碳氢化合物（HCs）组成和含量。光谱法、荧光法和色谱-质谱法。沼泽的水被证明含有来自泥炭沉积物（由植物产生）的碳氢化合物和热解碳氢化合物。Bolshoe 沼泽出现在有石油生产设施的地区附近，是唯一一个水中含有油烃的沼泽。最具代表性的 HCs 组是正构烷烃，其碳偏好指数 (CPI) 为 4.9-9.2。在脂环族 HC 中，检测到最高浓度的三萜，在 Bolshoe 和 Bakchar 沼泽中，taraxerene 和 neohop-13(18)-ene 占主导地位，在中央沼泽中以 diploptene 为主。根据甲基取代的多环芳烃 (PAH)、甾烷、hopanes 和 cheilanthanes 的存在以及通过降低的水中 CPI 确定了油烃污染，这些烃通过空气从石油和天然气生产设施转移。 Bolshoe 沼泽。2016 年火灾的影响是从未取代的多环芳烃的比率推断出来的。
