    • A method of screening a hydrocarbon stream for potential toxicological hazards. The method involves providing a hydrocarbon stream; conducting 2-dimensional gas chromatography (2D-GC) analysis to quantify saturates and aromatic distribution in the hydrocarbon stream; identifying 2-8 ring aromatic distribution and weight percentage of 2-8 ring aromatic molecules in the hydrocarbon stream from the 2D-GC analysis; relating the weight percentage of 2-8 ring aromatic molecules in the hydrocarbon stream from the 2D-GC analysis to a mutagenicity index (MI), in which the MI is determined in accordance with ASTM Standard Method E 1687; and assessing a potential toxicological hazard of the hydrocarbon stream based on the weight percentage of 2-8 ring aromatic molecules in the hydrocarbon stream from the 2D-GC analysis and a MI threshold value. The 2-8 ring aromatic distribution preferably includes 3-6 ring aromatics, more preferably 3.5-5.5 ring aromatics. The 2-8 ring aromatic distribution includes mono alkylated and multi alkylated aromatic molecules.
    • 筛选烃流以用于潜在的毒理学危害的方法。 该方法涉及提供烃流; 进行二维气相色谱(2D-GC)分析以量化烃流中的饱和物和芳族分布; 从2D-GC分析确定2-8环芳族分布和2-8环芳族分子在烃流中的重量百分比; 将来自2D-GC分析的烃流中的2-8环芳族分子的重量百分比与诱变指数(MI)相关,其中MI根据ASTM标准方法E1687测定; 并基于来自2D-GC分析的烃流中的2-8环芳族分子的重量百分比和MI阈值评估烃流的潜在毒理学危害。 2-8个环芳族分布优选包括3-6个环芳族化合物,更优选3.5-5.5个环芳族化合物。 2-8环芳族分布包括单烷基化和多烷基化芳族分子。
