Abstract—

The polyarene complex of soils was investigated, and PAH sources were assessed quantitatively in soils in the area subjected to heterogeneous technogenic impact near the town of Zhirnovsk, Volgograd oblast. The objects of study were the soils on interfluve areas within the oil and gas field, including soils of agricultural lands, floodplains, urban area, as well as oil-contaminated soils. PAH concentrations vary from 16 to 330000 ng/g; light PAHs, naphthalene and phenanthrene homologues are predominant; heavy PAHs were detected in the amount of 78.5 ng/g mainly in the urban area. The Positive Matrix Factorization (PMF) model was used to indicate and quantify the PAH sources. The following sources of PAHs were identified: emanation, old oil injection, new oil injection, traffic, public gas-pyrogenic, public wood-pyrogenic, and biogeochemical. They determine, respectively, the following associations of PAHs in soils: diphenyl, anthracene-chrysene, chrysene-naphthalene, fluorene-benzo[ghi]perylene, tetraphene-benzo[ghi]perylene, pyrene-anthracene-benzo[a]pyrene, and phenanthrene associations.

通过统计模型指示和定量评估土壤中的聚芳烃来源（石油和天然气开采区，伏尔加格勒地区）

摘要-

对土壤中的聚芳烃复合物进行了研究，并对伏尔加格勒州日尔诺夫斯克镇附近遭受非均质技术影响的区域中的土壤中的PAH来源进行了定量评估。研究的对象是油气田间交错区域的土壤，包括农田，洪泛区，市区的土壤以及受石油污染的土壤。PAH浓度从16到330000 ng / g不等；轻型PAH，萘和菲的同系物占主导地位；检出的重金属PAHs总量为78.5 ng / g，主要在城市地区。正矩阵分解（PMF）模型用于指示和量化PAH来源。确定了PAHs的以下来源：排放，旧注油，新注油，交通，公共气热原，公共木热原和生物地球化学。hi ] per，四苯并-苯并[ g ] per，pyr-蒽-苯并[a] py和菲的缔合。
