The assessment of aliphatic hydrocarbons was performed in the Sergipe River estuarine system, northeastern Brazil. Aliphatic hydrocarbons concentration ranged from 9.9 ug gâ1 up to 30.8 ug gâ1 of dry sediment. The carbon preference index (CPI, based on nC24 to nC34 range), indicated predominance of petrogenic input in two of the sites analyzed (P4 and P5). The unresolved complex mixture (UCM) was found to be present in seven of the nine sites sampled (except for P4 and P5). Overall, the results of this work suggest that there is a mix of organic matter sources to the sediment. Although the coast of Sergipe has an intense off shore petroleum exploration and the Sergipe River crosses the entire city of Aracaju, the capital city of Sergipe, non-significant anthropogenic fingerprint was assessed.
⺠Environmental quality in Sergipe River estuarine system was for the first time assessed. ⺠Hydrocarbon distribution was used for environmental quality evaluation. ⺠Data suggest a mix of sources to the sediments of Sergipe River estuarine. ⺠No significant anthropogenic activity has been identified.
