Identification of Organic Compounds in Great Lakes Fishes by Gas Chromatography/Mass Spectrometry: 1977

摘要

Samples of adult lake trout (Salvelinus namaycush) or walleye (Stizostedion v. vitreum) collected in 1977 from each of the Great Lakes and Lake St. Clair, as well as adult hatchery-reared lake trout, were analyzed for organic contaminants by gas chromatography/mass spectrometry (GC/MS). At each sampling site, twenty large fish were sampled and composited as whole fish into one sample and homogenized. Contaminants were extracted, isolated from lipids, separated on silica gel into two fractions, and analyzed by GC/MS. Organic compounds were identified by comparing the unknown mass spectra to the EPA/NIH library of 25,409 mass spectras.
