  • Title: Source identification and concentration distribution of polychlorinated biphenyls in environmental media around industrial complexes.
    Author: Park SU, Kim JG, Masunaga S, Kim KS.
    Journal: Bull Environ Contam Toxicol; 2009 Dec; 83(6):859-64. PubMed ID: 19471846.
    Abstract:
    In order to grasp the concentration distribution and identify sources of PCBs, air and soil samples around Sihwa and Banwol industrial area in Korea were analyzed. In result, the polychlorinated biphenyls (PCBs) concentration of air and soil was ranged from 2.08 to 5.82 ng/m3 (0.0686–1.01 pg WHO-TEQ/m3) and 2.43 to 274 ng/g dry (0.116–60.5 pg WHO-TEQ/g dry), respectively. Air and soil samples showed the very similar isomer composition pattern in each homologue by matrix, respectively. As a result of MLR for soil samples, the whole contribution rate of PCBs products (Aroclor) to soil was ~2 times higher than combustion.
