| Abstract: | "Our laboratory has been asked to elucidate the origin of a strong 'toxic smell' present in a prominent politician's office, private house and motorcar. This stinky and pungent atmosphere has caused serious nausea and vomiting to several individuals. Urine samples were collected from the persons presenting symptoms of nausea for toxicological analysis. Drops, paper and cotton swabs of an oily liquid found at the implicated places were submitted by police to our laboratory for investigation. Methanol extracts of the drops were acetylated for gas chromatography/mass spectrometry (GC/MS) analysis in the electron impact mode; the cotton and paper swabs were analysed using headspace-gas chromatography/mass spectrometry (HS-GC/MS). The GC/MS analysis of the acetylated methanol extracts revealed that the major peaks of the chromatogram could be attributed to 2-methylquinoline, to 2-quinolinemethanethiol, to S-2-quinolinemethyl thioacetate, to 2-phenylethanethiol, to bis(E)-2-butenyl disulphide and to bis(3-methylbutyl) disulphide. Several volatile sulphur-containing compounds have been identified with the HS-GC/MS system. Detailed examination of the spectra as well as GC/MS analysis of commercially available skunk secret allowed us to relate the identified compounds to those present in the defence spray of skunks. No health sequels were observed for any of the persons implicated in this case" |
