Abstract Bitumen and bitumen impacted soil and water samples were investigated for their relative chemical composition using comprehensive gas chromatography GcxGc – time of flight mass spectrometry (GCxGC-TOFMS). The results reveal the presence of key compounds which could serve as environmental biomarkers for bitumen impacted soils and aquifers. Prominent alkanes such as 3-methylpentane; 2,2,4-trimethylpentane; 1,3,5-trimethyladamantane; 2,6,10-trimethyldodecane; 3-ethyl-2,2-dimethyl pentane were tentatively identified and are likely potent biomarkers in environmental forensic assessment of bitumen contamination while the presence of some aromatic compounds: 1,2-benzenedicarboxylic acid, 1,2-dimethyl-3-propylbenzene; 3,4-bis(methoxycarbonyl)benzoic acid; 1,3-bezenedicarboxylic acid, 1,2-benzenediol; 1,3-dimethylbenzene; 1,2-2-(2-ethylhexoxycarbonyl)benzoic acid; (4-methylpentan-2-yl)benzene; 2,4-dimethyl benzo(H)quinolone will further confirm the bitumen contamination in an area under investigation. A host of additional compounds were tentatively identified, mainly in the bitumen samples. The results obtained in this study provides baseline data for effective monitoring, and source apportionment of oil/oil products spills.

使用综合气相色谱 GcxGc – 飞行时间质谱 (GCxGC-TOFMS) 初步评估环境样品中的沥青污染

摘要 使用综合气相色谱 GcxGc - 飞行时间质谱 (GCxGC-TOFMS) 研究了沥青和沥青影响的土壤和水样品的相对化学成分。结果揭示了关键化合物的存在，这些化合物可作为受沥青影响的土壤和含水层的环境生物标志物。突出的烷烃，如 3-甲基戊烷；2,2,4-三甲基戊烷；1,3,5-三甲基金刚烷；2,6,10-三甲基十二烷；3-乙基-2,2-二甲基戊烷被初步鉴定，可能是沥青污染环境法医评估的有效生物标志物，同时存在一些芳香族化合物：1,2-苯二甲酸、1,2-二甲基-3-丙苯；3,4-双(甲氧基羰基)苯甲酸；1,3-苯二甲酸，1,2-苯二醇；1,3-二甲苯；1、2-2-(2-乙基己氧羰基)苯甲酸；(4-甲基戊-2-基)苯；2,4-二甲基苯并（H）喹诺酮将进一步确认被调查区域的沥青污染。初步确定了许多其他化合物，主要是在沥青样品中。本研究获得的结果为石油/石油产品泄漏的有效监测和来源分配提供了基线数据。
