分析受污染土壤和水中石油碳氢化合物的方法受到一系列限制，这些限制来自废物-土壤-地下水基质的复杂性、溢出产品固有的化学多样性以及现场调查的要求。与难风化污染物相关的分析不确定性是一个主要问题，难风化污染物作为污染地下的残余饱和口袋而存在。采用透明、分阶段的废物定性方法可大大缓解这些制约因素，并改善现场调查资源的利用。此外，在这一方案中使用生物标志物监测和气相色谱-稳定碳同位素比质谱法，可能会对补救专家在阐明废物源术语和选择和监测补救处理技术方面产生重大益处。
Methods for the analysis of petroleum hydrocarbons in contaminated soil and water are subject to a range of constraints arising from the complexity of waste-soil-groundwater matrices, the inherent chemical diversity of the spilled product and the requirements of the site investigation. The analytical uncertainties associated with refractory weathered contaminants, which exist as pockets of residual saturation in the contaminated subsurface are a major problem. Adoption of a transparent, phased approach to waste characterisation significantly mitigates these constraints and improves the use of site investigation resources. Moreover, the use of biomarker monitoring and gas chromatography-stable carbon isotope ratio mass spectrometry within such a scheme is likely to be of significant benefit to remediation experts in the elucidation of waste source terms and the selection and monitoring of remedial treatment technologies.
