Quantifying natural vs. petroleum F3 hydrocarbons in oil spill impacted muskegs and drilling mud bioremediation applications

受石油烃污染的土壤和废物可对人类健康和环境造成高毒性风险，因此根据"加拿大土壤中石油烃标准"（加拿大环境部长理事会，2000年）进行管理。然而，碳氢化合物也由生物体如植物和动物自然产生。目前，化学武器系统协议将生物烃误认为石油烃。因此，最干净的有机土壤会被误认为是石油污染的物质，导致不必要的土壤修复和填埋处置的要求。这项研究建议将通过两个实验室为基础的模拟实验来解决虚假的石油烃污染。每个模拟将代表加拿大石油工业经常面临的问题。第一个实验将模拟原油管道泄漏在麝香草栖息地。第二个实验将模拟生物修复柴油基钻井泥浆，堆肥与粪便和秸秆。每种成分的独特化学特征将被分析，然后再组合到实验一和实验二中。将在6个月的研究期内记录化学变化。这些数据将用于开发一种从真实PHC浓度中减去BHC浓度的方法。该项目的主要成果将是建议改进和修订现有的化学武器系统石油分析协议。消除不必要的土壤补救和处置要求估计可为加拿大石油工业节省1 000万美元的费用。环境效益包括保护宝贵的垃圾填埋场空间和自然生境地区。

Petroleum hydrocarbon contaminated soils and wastes can pose high toxicity risks to human health and the environment and are therefore regulated in accordance with the "Canada-Wide Standards (CWS) for Petroleum Hydrocarbons (PHCs) in Soil (Canadian Council of Ministers of the Environment, 2000). However, hydrocarbons are also naturally produced by living organisms such as plants and animals. Currently, the CWS protocols misidentify biogenic hydrocarbons as petroleum hydrocarbons. As a result, the cleanest organic soils would be mistakenly identified as petroleum contaminated materials, resulting in unnecessary soil remediation and landfill disposal requirements.This research proposal will address false petroleum hydrocarbon exceedences through two laboratory-based simulation experiments. Each simulation will represent issues that are regularly faced by the Canadian petroleum industry. The first experiment will simulate a crude oil pipeline spill in a muskeg habitat. The second experiment will simulate the bioremediation of diesel-based drilling mud, composted with manure and straw. The unique chemical signatures of each component will be analyzed before they are combined into experiments one and two. Chemistry changes will be documented over a six-month study period. This data will be used to develop a method for subtracting BHC concentrations from true PHC concentrations. The major outcome of this project will be recommended improvements and revisions to the existing CWS petroleum analysis protocols. The elimination of unnecessary soil remediation and disposal requirements represents an estimated cost savings of $10 million dollars to the Canadian petroleum industry. Environmental benefits would include the conservation of valuable landfill space and natural habitat areas.
