Levels of coplanar PCB in flue gases of high temperature processes and their occurrence in environmental samples
article
Coplanar PCB (IUPAC nrs. 77, 126 and 169) have been determined in samples of flue gases and solid wastes from high-temperature processes, and soils and sediment. TEQ-levels of coplanar PCB present have been compared with those of PCDD/PCDF in the samples. It is found that, while in the flue gas samples coplanar PCB contribute less than 10% to the total TEQ level, soils and sediment may contain higher levels (up to 30% of the total TEQ for the samples analyzed). Moreover the pattern of PCB in the samples from high-temperature processes apparently differs considerably from that in the soils and sediment, in which PCB 77 constitutes >70% of the coplanar PCB. © 1994 Springer-Verlag.
