Abstract

Polychlorinated biphenyls (PCBs) were commercially produced as complex mixtures beginning in 1929. The PCBs manufactured commercially are known by a variety of trade names including; Aroclor (USA), Phenoclor (France), Kaneclor (Japan), Sovol (USSR) and so on. PCBs are a class of 209 congeners that were widely used in a wide variety of applications, including dielectric fluid in transformers and large capacitors; heat transfer fluids; hydraulic fluids; lubricating and cutting oils; and as additives in pesticides, paints, adhesives, sealants, and plastics. The quantification methods of peak matching and coefficient comparison were compared using the Aroclor 1242, 1248, 1254, 1260 standards. Also, six transformer oils were analyzed as a main source of polychlorinated biphenyls (PCBs) emission into the environment. The transformer oils contained the pure and mixed of Aroclor 1242, Aroclor 1254, and Aroclor 1260. The analytical results using two quantification methods showed the little difference between the measured results.

1929년부터 상업적으로 사용되기 시작한 폴리염화비페닐류(PCBs)는 Aroclor (미국), Kanechlor (일본), Sovol (러시아) 등 다양하게 상업적으로 시판되었다. PCBs는 209종의 동족체로 구성되어 있으며 변압기, 축전기의 절연유, 윤활유, 가소제, 도료, 복사지 등의 여러 용도로 사용되어 온 산업용 화학물질이다. 본 연구에서는 시판되는 PCBs Aroclor 제품을 구입하여, 표준물질을 사용하여 피크패턴법에 의한 정량방법과 계수비교법에 의한 정량방법을 비교하고, 시료에 적용하여 분석하였다. 분석대상 시료의 피크패턴은 Aroclor 1242:1254:1260의 세 종류가 혼합된 경우와, Aroclor 1242:1254, Aroclor 1254:1260이 혼합된 경우 그리고 Aroclor 1242, 1254 및 1260이 혼합된 시료가 다양한 비율로 검출되었다. 또한, 두 정량법에 따른 분석 결과는 혼합된 PCBs 제품의 종류가 한 종류인 경우 보다 여러 종류일수록 두 정량값의 차이가 없는 것으로 나타났다.
