Abstract

A comparative analysis of the current content of petroleum hydrocarbons in various components of the ecosystem was performed to assess the ecological state of the southeastern part of the Onega Bay (White Sea) that suffered from a spill of fuel oil in 2003. The analysis showed relatively low levels of petroleum hydrocarbon concentrations: from 0.34 to 4.55 mg/kg, with a median of 1.41 mg/kg in bottom sediments; from 9.41 to 14.25 mg/kg, with a median of 12.30 mg/kg in tissues of benthic organisms; and below 1 MPC_fishery (the maximum permissible concentration) in water. The records of low concentrations of bacteria that use petroleum hydrocarbons (fuel oil) allow us to conclude that the state of the examined ecosystem is close to the natural condition.

燃油污染对白海奥涅加湾沿海生态系统的长期影响

摘要

对生态系统各个组成部分中石油烃的当前含量进行了比较分析，以评估2003年因燃料油泄漏而遭受的Onega湾（白海）东南部的生态状况。石油烃浓度低：从0.34至4.55 mg / kg，底部沉积物中位数为1.41 mg / kg；在底栖生物组织中为9.41至14.25 mg / kg，中位数为12.30 mg / kg；且水中的MPC_捕捞量低于1 MPC （最大允许浓度）。使用石油碳氢化合物（燃料油）的细菌浓度低的记录使我们可以得出结论，所检查的生态系统状态接近自然条件。
