Project Tocoen: The fate of selected organic pollutants in the environment part xxiv. The content of PCBs and PCDDs/Fs in high‐mountain soils

Abstract

The six high‐mountain soil samples (more than 1,100 m above sea level) from National Park Krkonose (North Bohemia, Czech‐Polish border) were analyzed for contents of PCBs, non‐ortho and mono‐ortho PCBs and PCDDs/Fs. The content of PCBs ranged between 31 and 137 ng.g^‐1 dry soil. PCB 77 was predominant coplanar PCBs. The contents of PCDDs/Fs ranged between 17 and 29 pg.g‐¹ 1‐TEQ of PCDDs/Fs and were between 20.1 and 41.2 pg.g^‐1 T‐TEQ of PCDDs/Fs and coplanar PCBs. The contents of PCDFs were significantly higher than those of PCDDs. The predominant congeners were OCDF and OCDD. The contribution of non‐ortho and mono‐ortho PCBs to the total 1‐TEQ ranged between 9.3 and 49.3%.
