FINGERPRINTING MARINE POLLUTANT HYDROCARBONS BY COMPUTERIZED GAS CHROMATOGRAPHY-MASS SPECTROMETRY
A series of petroleum hydrocarbons of geochemical significance (biological markers), e.g., C sub 20-C sub 40 acyclic ispoprenoids and C sub 27+steranes and triterpanes are proposed as passive tags for the characterization of oils in the marine environment. Mass-fragmentography of samples was used to make evident these series of components without complex enrichment treatments. The rational choice of the characteristic ions is discussed, and molecular and stereoisomeric profiles are considered for identification purposes. Computerized GC-MS permits multiple fingerprinting from the same GC run. Rapid and effective comparisons between samples and long term storage of the results for future examination can be conducted. Differences between oils from the same geographic area and correlations of highly weathered samples are exemplified.
