Chlorinated dioxin trrends between 1987 and 1993 for samples of crab hepatopancreas from pulp and paper mill and harbour sites in British Columbia

This study employs principal components analysis (PCA) to explore the interrelationships and trends in both the chlorinated dibenzo-p-dioxin and dibenzofuran patterns and the toxic congener composition among British Columbia pulp and paper mill sites, and between harbours and mill sites. The researchers applied PCA to a large data set of the concentrations of dioxins and furans in samples of crab hepatopancreas from locations in the vicinity of British Columbia coastal mills and the principal harbours in the province. PCA distinguishes harbour samples from mill samples, reveals differences between individual mill sites, and reliably classifies the dioxin and furan congener patterns according to chlorine bleaching, digested polychlorinated phenol, and pentachlorophenol wood preservative sources. PCA is also used to assign sources to individual crab samples. The study results indicate the changes in dioxin and furan congener composition over time.
