The Arctic environment is very vulnerable and sensitive to hydrocarbon pollutants. Soil bioremediation is attracting interest as a promising and cost-effective clean-up and soil decontamination technology in the Arctic regions. However, remoteness, lack of appropriate infrastructure, the harsh climatic conditions in the Arctic and some physical and chemical properties of Arctic soils may reduce the performance and limit the application of this technology. Therefore, understanding the weaknesses and bottlenecks in the treatment plans, identifying their associated hazards, and providing precautionary measures are essential to improve the overall efficiency and performance of a bioremediation strategy. The aim of this paper is to review the bioremediation techniques and strategies using microorganisms for treatment of hydrocarbon-contaminated Arctic soils. It takes account of Arctic operational conditions and discusses the factors influencing the performance of a bioremediation treatment plan. Preliminary hazard analysis is used as a technique to identify and assess the hazards that threaten the reliability and maintainability of a bioremediation treatment technology. Some key parameters with regard to the feasibility of the suggested preventive/corrective measures are described as well.
北极环境对碳氢化合物污染物非常脆弱和敏感。土壤生物修复作为一种有前途和具有成本效益的清洁和土壤去污技术，在北极地区引起了关注。然而，偏远、缺乏适当的基础设施、北极恶劣的气候条件以及北极土壤的某些物理和化学特性可能会降低该技术的性能并限制其应用。因此，了解处理计划中的弱点和瓶颈，确定其相关危害，并提供预防措施，对于提高生物修复策略的整体效率和性能至关重要。本文的目的是综述使用微生物处理受碳氢化合物污染的北极土壤的生物修复技术和策略。它考虑了北极的操作条件，并讨论了影响生物修复处理计划性能的因素。初步危害分析被用作一种技术，用于识别和评估威胁生物修复处理技术可靠性和可维护性的危害。还描述了一些关于建议的预防/纠正措施的可行性的关键参数。
