Abstract:Persistent, bioaccumulative, and toxic (PBT) substances are a continuing cause of concern because of their effects on environmental and human health. The objectives of this pilot study were (1) to develop a screening method that could be used for the extraction and analysis of a group of 10 PBT compounds selected from the priority lists of Muir and Howard (2007) and (2) to apply those methods to measure the concentrations of these analytes in lake trout collected from Lake Michigan. These compounds included 1,2,3,4,5-pentabromo-6-chlorocyclohexane (PBCCH); 1,2,5,6,9,10-hexabromocyclododecane (HBCDD); 1,2,3,4,5,5-hexachloro-1,3-cyclopentadiene (HCCPD); 3,4,4'-trichlorocarbanilide (TCCBA); 3,4-dichlorobenzotrifluoride (DCBTF); 4-chloro-3,5-dinitrobenzotrifluoride (CDNBTF); triphenylphosphine (TPPine); 2,4,6-tri-tert-butylphenol (TTBP); dodecamethylpentasiloxane (DDMPS); and dodecamethylcyclohexasiloxane (DDMHS). Difficulty was encountered in obtaining reference materials for TTBP and DDMHS. Thus, triphenylphosphite (TPPite) was substituted for TTBP, and DDMHS was omitted from the list.Standard solvent extraction, gel permeation chromatography (GPC), and silica gel chromatography (SGC) methods were applied and modified as necessary for the clean-up preparation of fish samples. This included a serial evaluation of GPC elutants, which indicated the 150 to 350 mL fraction yielded the best results. Subsequently, an evaluation of SGC elutants revealed that the first two fractions combined yielded the best results. After solvent extraction, the quality control and fish samples were analyzed via gas chromatography/mass spectrometry (GC/MS) along with a set of calibration standards.
