The influence of anthropogenic pollution, particularly with polycyclic aromatic hydrocarbons (PAHs) on soil toxicity and spread of antibiotic resistance genes (ARGs) is extremely important nowadays. We studied 20 soil samples from a technogenically polluted site, municipal solid wastes (MSW) landfills, and rural settlements in the southwestern part of the Rostov Region of Russia. A close correlation was established between the results of biosensor testing for integral toxicity, the content of genes for the biodegradation of hydrocarbons, and the concentration of PAHs in soils. The relation between the quantitative content of ARGs and the qualitative and quantitative composition of PAHs has not been registered. Soils subjected to different types of the anthropogenic pressure differed in PAHs composition. The technogenic soils are the most polluted ones. These soils are enriched with 5 ring PAHs and carry the maximum variety of assayed ARGs, despite the fact that they do not receive household or medical waste.

如今，人为污染，特别是多环芳烃（PAHs）对土壤毒性和抗生素抗性基因（ARGs）传播的影响极为重要。我们研究了来自技术污染地点，城市固体废物（MSW）垃圾填埋场和俄罗斯罗斯托夫州西南部农村地区的20个土壤样品。在生物传感器的整体毒性测试结果，碳氢化合物生物降解基因的含量以及土壤中PAHs的浓度之间建立了密切的关联。ARGs的定量含量与PAHs的定性和定量组成之间的关系尚未记录。遭受不同类型人为压力的土壤中PAHs组成不同。技术性土壤是污染最严重的土壤。这些土壤富含5个环PAH，并且携带的被分析的ARG种类最多，尽管它们不接受家庭或医疗废物。
