Polycyclic aromatic hydrocarbons (PAHs) and geochemical biomarkers are good environmental markers to study the origin and evolution of an oil spill. To have access to the greatest number of molecular ratios, no fractionation of oil into aliphatic and aromatic compounds is made. Three analytical MS approaches are tested to analyze markers in this total hydrocarbon fraction: classical quadrupole GC-MS, high resolution GC-MS (HR GC-MS) and metastable reaction monitoring GC-MS-MS (MRM GC-MS-MS). This analytical approach is used to follow the evolution of PAHs in petroleum polluted mangrove soils over 8 years by using molecular ratios between polycyclic aromatic hydrocarbons and tri- and tetracyclic terpanes.
多环芳烃（PAHs）和地球化学标志物是研究石油泄漏起源和演化的良好环境标志物。为了获得最多的分子比率，不对油进行脂肪族和芳香族化合物的分馏。测试了三种分析质谱方法来分析该总烃馏分中的标志物：经典四极杆气相色谱-质谱联用仪（GC-MS）、高分辨率气相色谱-质谱联用仪（HR GC-MS）和亚稳反应监测气相色谱-串联质谱联用仪（MRM GC-MS-MS）。通过使用多环芳烃与三环和四环萜烷之间的分子比率，这种分析方法被用于追踪石油污染红树林土壤中多环芳烃8年的演化情况。
