摘要：

Sediments sampled within the bed of the Coatzacoalcos river of Veracruz, Mexico, were used as geo-accumulators for the assessment of the status of petroleum pollution in the Coatzacoalcos river. Stable carbon isotope ratios and the composition of aliphatic and aromatic hydrocarbons were determined in order to evaluate the importance of the petrogenic inputs as well as to ascertain their spatial distribution. Molecular markers, namely acyclic isoprenoid hydrocarbons, steranes and hopanes, were studied for source identification. As a result, high levels of petroleum were found in the whole studied area, with no defined spatial trends, corresponding to an overall pollution by the same type of crude oil products.
