Isomeric-specific analysis of composition of technical PCB mixtures: Sovol, Sovtol and Trichlorodiphenyl
T12N3
A.A. Shelepchikov, E.S. Brodsky
Comparative isomer-specific analysis of technical mixtures of PCBs produced in USSR/Russia and USA was carried out. The study was performed by gas chromatography/high resolution mass spectrometry using stable isotope labeled standards. In each sample, 166 individual congeners or unresolved compounds representing all 209 PCB congeners were determined. The data showed that different lots of the same technical PCB mixtures had significant differences in the congeners pattern. PCB mixtures produced in the USSR (Russia), had group composition and relative abundance of indicator congeners which are similar to American Aroclors, but showed important differences in fine congeners distribution.
