SPATIAL BIOMONITORING OF POLYCHLORINATED BIPHENYL AND POLYBROMINATED DIPHENYL ETHERS IN TIBETAN PLATEAU USING TIBETAN BUTTER

摘要：

In the present study, Tibetan butter samples were collected from different prefectures in Tibet Autonomous Region (TAR) to investigate the spatial distributions of polychlorinated biphenyl (PCBs) and polybrominated diphenyl ethers (PBDEs). ∑25PCB concentrations ranged from 137.3 to 2518 pg g-1 with a mean value 518.5 pg g-1, which were far lower than those in the butter from other worldwide regions. The average concentration of ∑12PBDE was 124.6 pg g-1, which was comparatively lower than PCBs. Back trajectory model and principal component analysis indicated the source of these two groups of persistent organic pollutants were mainly from the global long-range transport via to cold trap in this region.
