We based reference half-lives of PCB-77 and PCB-81 on measurements from samples of adipose tissue, whereas we determined reference half-lives for the 10 remaining PCB congeners based on measurements of blood (Ogura 2004).
We based reference half-life values for infants on congener-specific values reported by Leung et al. (2006) where available.
In this study we provide congener-specific reference half-life values for adults and infants and a method of half-life estimation based on individual characteristics.
For 1,2,3,7,8,9-HxCDF, which had no available half-life data, we used the reference half-life for 1,2,3,6,7,8-HxCDF.
We found the slope (βage) and the intercept [β0 age)] coefficients by using a linear interpolation between the infant and adult reference half-lives (shown in Tables 5 and 6).
We preferentially used the regression method used by Flesch-Janys et al. (1996) for adult reference half-life values because it covers multiple congeners in a consistent way and incorporates information for percent body fat, sex, and smoking status, and because the resulting values are within the range of the other values in the literature.
We used a Sirius electrode which is based on a Ag/AgCl reference half-cell and is made in the U.K. Compounds 1− 44 were obtained from commercial sources except for trifluoromethanesulfonamide (35) and its N-phenyl (33) and N-methyl (34) derivatives.
For dioxin and furan congeners not reported by Flesch-Janys et al. (1996), we used the model proposed by Van der Molen et al. (2000) to determine a reference half-life, using the median age (48.7 years) and percent body fat (21.9%) from Flesch-Janys et al. (1996).
With a stage persona that matches a cocky attitude on loan from hip-hop with the wacky energy of a Super Ball, Minhaj tends to bury his material under a barrage of pop-culture references — half panderingly nostalgic, half perishably current — that render long stretches of script incomprehensible to anyone outside his demographic.
One should realize that we only presented an interesting case report and in its current form we provided 25 references, half of which dealt specifically with modular component corrosion, which in our opinion is a lot for a case report already.
