摘要: Abstract Two fuel oils and two crude were subjected to a 60-day weathering simulation experiment, the effects of on some common parameters for aromatics aromatic δ13C values studied. The results show that all oil samples affected little DBT/P (dibenzothiophene/phenanthrene) ratio methylphenanthrene distribution fraction. Four could be distinguished only by ratio. effect isotopes in polycyclic hydrocarbons was small. types four can distinguished, while Kuwait Russia cannot discriminated from each other totally double-coordinate two-dimensional maps δ13C; principal component analysis aromatics, relationship PAHs values. Therefore, value used as an alternative index spills.
