Abstract

The untargeted approach allowed recognizing different classes of compounds, mainly hydrocarbons from C-20 to C-30. Besides, two chemicals, deriving from anthropic activities, N-butylbenzenesulfonamide (NBBS) and di phenyl sulfone (DPS), were identified and quantified in all samples. Both analytes showed decreasing concentrations from the more confined site to the outer one. The oceanographic characterization of the area performed with multiparametric probes provided useful information, in agreement with chemical analyses. The presence of NBBS and DPS in the site presenting lower continental inputs demonstrated the usefulness of the integrative sampling approach for temporal and spatial monitoring, especially for low level and/or short-term pollution events that traditional monitoring can fail to detect.
