This fact is due to the presence of highly-chlorinated congener OCDD and also because of elevated concentrations of furans (Table 4).

The dioxin and furan congeners thought to be most toxic to humans are the seven dioxins (including OCDD and 1,2,3,4,6,7,8-HpCDD) and 10 furans with chlorines occupying at least the 2,3,7, and 8 positions (Figure 1).

OCDD is very insoluble, and therefore difficult for the body to absorb, Birnbaum says.

This 'nontoxic' dioxin isn't

TEQ values were calculated using seven mono- and non-ortho-substituted dioxin-like PCBs (PCBs 126, 169, 105, 118, 156, 157, 189) and OCDD as described by Van den Berg et al.

When we entered thyroid volume as the dependent variable and concentrations of the seven most toxic PCDD congeners [TCDD, 1,2,3,7,8-pentachlorinated CDD (PeCDD), 1.2.3.4.7.8-HxCDD, 1,2,3,6,7,8-HxCDD, 1.2.3.7.8.9-HxCDD, 1,2,3,4,6,7,8-hepta-chlorinated CDD (HpCDD), and octa-chlorinated CDD (OCDD)] as independent variables, cross-tabulation for samples > LOD reduced the number of individuals to an insufficient 25.
