摘要：Polychlorinated biphenyls (PCBs) have been placed on the list of persistent organic pollutants by the Stockholm Convention in 2001 because of their high persistence, the bioaccumulation along the food chain and high toxicity. An area of concern in terms of pollution by these compounds is the landfill Glina. This paper aims to do a study on the presence of polychlorinated biphenyls in Glina soils and in their migration on soil profile. Soil samples were collected from six depths on five profiles (between 0 and 100 cm). Measurement by gas liquid chromatography with specific detection (capture electron detector) and capillary column (with specific non polar stationary phase) showed that only one of the five profiles is significantly polluted with PCB compounds. Thus, PCB 52 (with four chlorine atoms in the molecule) and PCB 101 (with five chlorine atoms in the molecule), were found with values exceeding approximately ten times the alert threshold of 0,002 mg/kg. Also, the content of highly chlorinated isomers (PCB 138, PCB 153 and PCB 180) were just above the intervention threshold of 0,04 mg/kg. The total content of PCBs compounds are ranged between 0,1401 mg/kg and 0,422 mg/kg, thus exceeding the alert threshold values of 0,25 mg/kg, but not reach the threshold of intervention of 1mg/kg. Although PCB compounds are quite immobile compounds in soil, they were found in deeper soil layers. This is possible if these compounds have been present in soil for years or due to disruption of soil layers, common situation in urban soils
