10 l Surrogate (2,4,5,6-tetrachloro-m-xylene) and internal standard (decachlorobiphenyl PCB congener 209) were spiked into the samples and blanks.
Then the indicator PCBs, dioxin-like PCB congeners and three lightly chlorinated biphenyls (PCB-11, 15, 19) and total PCBs (from Mono-CBs to Deca-CBs) were quantitatively analyzed both in wastewater and sludge at each treatment stage in the WWTP The distribution of PCBs between the dissolved and adsorbed phases in the influent and effluent of each treatment stage was investigated as well.
The mean of total concentration of PCBs (15 congeners) in Japanese mother's milk samples collected from four areas were found to be as 64.50ng/g for Hokkaido, 78.48ng/g for Miyagi, 54.95ng/g for Gifu, and 109.44ng/g for Hyogo (Inoue et al., 2006).
* Fusel oil is the most abundant group of congeners produced as a byproduct.
Despite their close genetic relationship and the hosting of common pollinators, the congeners differ in stature, number of racemes per plant, and to some extent, flowering period (Haddock and Chaplin 1982).
The lack of reporting of this congener on the EPA-TRI site, given the demonstration of 2,3,7,8-TCDD on the site, further calls into question the reliability and utility of the EPA-TRI data as a means of assessing public health risk.

The spiked samples and control (the congener free sample) were then allowed to pass through the following extraction and clean-up procedures before GC-u-ECD instrumental analysis.
The term "PCBs" refers to a family of compounds including 209 congeners, which are divided into two main groups: "dioxin-like PCBs (DL-PCBs)" and "non-dioxin-like PCBs (NDL-PCBs)".
