Abstract
The pollution by PCB [polychlorinated biphenyls] in the air inside the buildings of an electrical industry was measured. Three sampling and analytical methods were tried and the differences in their accuracies were estimated. Based on these results but also taking into account the need of an easy and practical implementation, a particular method was chosen whose precision was measured under different conditions of collection. This method was used to measure the air concentration of PCB in personal and fixed location samplers. Area samplers were located in a number of indicative positions inside the rooms in the factory. Personal samplers were collected on the staff during the work shifts.
