A six month field scale study was carried out to compare windrow turning and biopile techniques for the remediation of soil contaminated with bunker C fuel oil. End-point clean-up targets were defined by human risk assessment and ecotoxicological hazard assessment approaches. Replicate windrows and biopiles were amended with either nutrients and inocula, nutrients alone or no amendment. In addition to fractionated hydrocarbon analysis, culturable microbial characterisation and soil ecotoxicological assays were performed. This particular soil, heavy in texture and historically contaminated with bunker fuel was more effectively remediated by windrowing, but coarser textures may be more amendable to biopiling. This trial reveals the benefit of developing risk and hazard based approaches in defining end-point bioremediation of heavy hydrocarbons when engineered biopile or windrow are proposed as treatment option.
进行了为期六个月的野外规模研究，以比较条垛翻堆和生物堆技术修复受船用燃料油 Bunker C 污染的土壤。通过人体风险评估和生态毒理学危害评估方法来定义终点清理目标。在重复的条垛和生物堆中添加营养物和接种物、仅营养物或不添加任何物质。除了进行烃类分组分析外，还进行了可培养微生物特征和土壤生态毒性测定。这种质地较重且历史上受到船用燃料污染的土壤通过条垛翻堆处理得到了更有效的修复，但较粗的质地可能更适合生物堆处理。该试验表明，在提出工程生物堆或条垛作为处理方案时，基于风险和危害的方法在确定重质烃类生物修复终点方面具有优势。
