Analysis of PCBs in air samples collected at facilities related with PCB containing products or wastes
Polychlorinated biphenyls (PCBs) are classified and regulated as one of the 12 persistent organic pollutants (POPs) under the Stockholm Convention on POPs. The present study analyzed PCBs in samples collected from several types of facilities related to PCB containing products or wastes in South Korea. The results showed that total PCB concentrations ranged from 37 pg m-3 to 104,048 pg m-3 and from 106 pg m-3 to 13,382 pg m-3 in indoor and outdoor air samples respectively. In air samples elevated abundances of lighter congeners, such as mono-, tri-, etc. were found as compared with the technical products. The principal component analysis of PCB profiles showed that the homologue pattern of PCBs in outdoor and indoor air samples collected from the facilities similar to that of background air samples and the PCB product mixture of Aroclor 1016, Aroclor 1221, Aroclor 1232 and Aroclor 1242. These results suggested that PCB emissions during the production, recycling, use and disposal of PCB containing products or wastes were the important sources to atmospheric PCBs in South Korea.. This is the first study to investigate PCB emission from facilities related with PCB containing products and wastes in South Korea.
