Capillary gas chromatography (GC) combined with mass spectrometry (MS) and atomic emission spectroscopy (AED) was utilized for a comprehensive investigation of organic micropollutants in a marine sediment. Most compounds were found and identified by CC-MS library search. The elemental information from GC-AED was utilized for confirmation purposes, for analyte characterization in cases where identification by CC-MS was impossible, and for screening on heteroatomic components. In addition, GC-AED was effectively used for the quantitative part, where the total amount of GC amenable material, classes of compounds, and individual components were determined.
