Because our PCB analytical laboratory monitors 101 congeners and DDE, HCB, and mirex, we have greater ability than most to determine differences in actions of the various congener groups and pesticides.
Breastfed infants have the highest uptake rates (Table 2); for the different PBDE congeners, they are 8-84 times higher than the uptake rate of infants above 3 months of age (see Supplemental Material, Table S4).
Table 3 shows the association between selected PCB congeners and PCB groupings and metastatic prostate cancer in the Janus study.
We used Pearson correlations to assess the correlation between concentrations of the four PBDE congeners and between prenatal and child (at age 7 years) PBDE blood concentrations.
Furthermore, as reviewed by Hansen (1998), many epidemiological studies have assessed exposure based on the analysis of limited subsets of PCB congeners selected because of their toxicological similarity to dioxin, their relative occurrence in biological samples, and/or the ease with which they can be detected using a given analytical method.
The problem might not be the congeners themselves, however, but, like alcohol, how your body processes them.
Logistic regression was used to obtain crude (adjusted only for matching factors) and multivariable adjusted odds ratios (OR) and 95% confidence intervals (CI) for the association between the categorized (quartiles) congeners and ASD in comparison to GP controls.
PCB congeners were identified and quantified based on previously reported methods [37].
The alcohols with the most congeners are brandy, red wine, bourbon, dark rum and whiskey.
