Congener-Specific Carbon Isotopic Analysis of Technical PCB and

To evaluate the utility of carbon isotopes, determination of isotopic ratios of 13C/12C in source materials, for example, technical PCB preparations, is needed. In this study, we determined Î´13C values of 31 chlorobiphenyl (CB) congeners in 18 techn
