Abstract—

The assimilation potential to oil and oil hydrocarbons is assessed for the first time for different soil types of Azerbaijan. The soil assimilation potential is understood as the buffering capacity of soils to sustain a certain anthropogenic impact without changing their principal properties and ecological functions for a long period. Estimation of assimilation potential of a territory is necessary for assessing the actual self-purification capacity of environmental components as a national ecological resource under the conditions of constantly growing anthropogenic impact on the environment. For assessing the assimilation potential of soils in respect to oil hydrocarbons, the value of bacterial biodegradation of oil hydrocarbons has been evaluated according to the amount of hydrocarbon-oxidizing bacteria and the number of hydrocarbons that are oxidized by one bacterial cell. It is found that the assimilation potential of different soil types in Azerbaijan (provided they are contaminated with oil hydrocarbons) varies from 1 t/ha per year for solonchaks to 12.5–13.1 t/ha per year for chestnut (Kastanozems) and mountain chernozemic (Chernozems) soils. The index of actual assimilation potential for various soil types may be accepted as the upper safe level of the permissible hydrocarbon concentration.

基于同化势确定不同土壤类型的石油和石油产品最大允许浓度的方法（以阿塞拜疆土壤为例）

摘要—

首次评估了阿塞拜疆不同土壤类型对石油和石油烃的同化潜力。土壤同化潜力被理解为土壤在长期不改变其主要特性和生态功能的情况下维持一定的人为影响的缓冲能力。在不断增加的人为环境影响的条件下，估算一个地区的同化潜力对于评估作为国家生态资源的环境要素的实际自我净化能力是必要的。为了评估土壤对石油烃的同化潜力，根据碳氢化合物氧化细菌的数量和被一个细菌细胞氧化的碳氢化合物的数量，已经评估了石油碳氢化合物的细菌生物降解价值。研究发现，阿塞拜疆不同类型土壤的同化潜力（假设它们受到石油烃的污染）从solonchaks每年1吨/公顷到栗子（Kastanozems）和山黑钙土（每年12.5-13.1 t /公顷）不等。黑钙土）土壤。各种土壤类型的实际同化潜力指数可以作为允许的碳氢化合物浓度的最高安全水平。栗子（Kastanozems）和山黑钙土（Chernozems）每年1吨/公顷。各种土壤类型的实际同化潜力指数可以作为允许的碳氢化合物浓度的最高安全水平。栗子（Kastanozems）和山黑钙土（Chernozems）每年1吨/公顷。各种土壤类型的实际同化潜力指数可以作为允许的碳氢化合物浓度的最高安全水平。
