Two approaches are proposed for the identification of a contaminant
caused by the spilling of oil or oil products in water. A capillary gas chromatography
(CGC)–mass spectrometry (MS) method for oil spill identification is applied.
The presented approaches describe the use of MS data of 18 selective ions of
spilled product and the probable pollutant. The spill identification is accomplished
on the bases of a quantitative comparison between the ion chromatograms of
the samples taken from the probable pollutant and from the spill itself. The
other approach is made by chemometric treatment of complete CGC–MS data.
