Total Petroleum Hydrocarbons (TPH) represent major environmental contaminants which pose a significant risk to ecosystems and humans heath if left untreated. Bioremediation represents a simple, cheap and environmentally-safe approach to clean up TPH-contaminated sites. Traditional TPH analysis is expensive and time-consuming. Here we assess, for the first time, the potential of RemScan as a fast, accurate and cost-effective portable device to be used as a tool to monitor the bioremediation process. A variety of TPH-contaminated soils were subject to TPH quantitative analysis using RemScan. The TPH values obtained were validated and compared against the results obtained from an accredited external laboratory, which uses Gas Chromatography / Mass Spectrometry (GC/MS) for TPH analysis. •RemScan showed a correlation coefficient (R) of 0.998 in comparison with the traditional methods, but importantly with a significant reduction in both time and cost.•RemScan was successfully used to measure TPH concentrations in bioremediated, weathered-contaminated and highly contaminated soil samples with TPH concentrations varying from 100 to 100,000 mg kg.•The RemScan Laboratory Station was used to minimize the source of errors associated with human manual handling.
总石油烃（TPH）是主要的环境污染物，如果不进行处理，会对生态系统和人类健康构成重大风险。生物修复是一种清理受TPH污染场地的简单、廉价且环境安全的方法。传统的TPH分析既昂贵又耗时。在此，我们首次评估RemScan作为一种快速、准确且经济高效的便携式设备，用作监测生物修复过程工具的潜力。使用RemScan对多种受TPH污染的土壤进行TPH定量分析。将获得的TPH值进行验证，并与使用气相色谱/质谱联用仪（GC/MS）进行TPH分析的认可外部实验室所得结果进行比较。•与传统方法相比，RemScan的相关系数（R）为0.998，但重要的是时间和成本都大幅降低。•RemScan成功用于测量生物修复、风化污染和高污染土壤样品中的TPH浓度，TPH浓度范围为100至100,000毫克/千克。•使用RemScan实验室工作站将与人工操作相关的误差源降至最低。
