Abstract:
Human adipose tissue samples obtained during autopsies in 5 Canadian municipalities within the Great Lakes basin were analysed for polychlorinated dibenzodioxins and dibenzofurans using gas chromatography-high resolution-mass spectrometry. The mean congener values for male and female donors in each municipality are comparable with previously reported data. No significant differences in congener levels between male and female and between municipalities were detected. A positive correlation between congener level and age was observed for several congeners as well as for the total congener concentration expressed as its 2378-TCDD toxic equivalent.
