Measurements of polychlorinated biphenyls (PCBs) were taken in surface sediments inside Seogwipo and Hallim Harbors of Jeju Island, Korea, to evaluate their distribution. These harbors typically have heavy ship traffic. The samples were collected three times (in June, October, and December, 2013). P...

PCBs란 무엇인가? | PCBs (Polychlorinated Biphenyls)는 2개의 페닐기에 1~10개의 염소원자로 치환된 비극성의 염소화된 탄화수소로 두 개의 페닐기의 수소가 무수염소와 반응하여 염소화될 때 생성되는 화학적으로 매우 안정한 유기화합물이다. 2개의 페닐기에 치환된 염소원자의 수와 위치에 따라 209개의 동종체(congener)가 존재하고 있으며 이 중 약 100여개의 동종체가 실제 사용되고 있다(Hutzinger et al. | |
한림항내 수면적은 어느 정도인가? | 한림항은 제주도 서북쪽에 위치하고 있으며 연안항으로 연근해 어업의 중심지이며 각종 어류와 해조류가 풍부하고 지하해수의 용출 등 수산업이 발달하기에 좋은 여건을 가지고 있다. 항내 수면적은 348,000 m2으로 내측의 수심은 4 m 정도이고 방파제 외측부근은 10 m 정도이며 항구 외해의 북서쪽은 수심이 20 m 정도로 조사해역 중 가장 깊고 서 방파제 외측부근은 수심 10 12 m 정도이다. | |
PCBs의 용도는 무엇인가? | PCBs는 전기절연성, 화학적 열적 안정성, 낮은 가연성, 화학적 부식에 대한 저항성 및 일반적인 비활성의 특성으로 축전기, 변압기의 절연유, 윤활유, 가소제, 도료, 복사지, 농약 등의 첨가제 등을 포함한 다양한 용도로 1930년부터 1993년까지 전 세계에서 130만톤이 생산되었으며(Petersen-Bjergaard et al., 1996; Breivik et al. |
