Even though congeners occur in very tiny amounts, some of them are considered toxic.
We also considered alternate strategies for replacing values <LOD (for congeners detected in at least 55% of samples); these included using lab-read values for low sample volumes originally censored to <LOD (uncensored data) and multiple imputation using SAS PROC MI (SAS 2015).
Based on the similarity-intermiscibility theory, PCB-52, PCB-87, and PCB-99 have relatively lower [K.sub.OW] among the PCB congeners. And HEX/ACE also has relative lower [K.sub.OW] than other solvents.
Although some studies suggest that lower-brominated PBDEs represent the primary congeners of concern for pregnant and nursing women [64, 79, 84], recent evidence suggests that higher-brominated PBDEs may undergo metabolic debromination and then transfer to the neonate or nursing infant as a more toxic metabolite or lower-brominated PBDE [26, 85].
A commercial mixture of 19 PCB congeners, 20 organochlorine pesticides, five internal standards and four surrogates was used to prepare calibration curves ranging from 0.5 to 200 ppb.
The retention time window were established through five injections of 19 PCBs standard congeners over a period of 72 h and the retention time was recorded for each congener to three decimal places [38].
Here, the mainly concerned PCBs were 20 individual PCB congeners and total PCBs (from Mono-CBs to Deca-CBs).
Identification and quantification of 2,3,7,8-substituted congeners of PCDDs D[Fs.sup.-1] and dioxin-like PCBs (non-and mono-ortho-substituted congeners) was performed by using a (i) Shimadzu GC-14B gas chromatograph with AOC-1400 auto-sampler.
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).
Congeners exert their greatest impact on some spirits because by distillation they become concentrated in them.
