Abstract

Persistent Organic Pollutants (POPs) are chemical substances which persist in the environment, bioaccumulate through the food web, and pose a risk of causing adverse effects to human health and the environment. POPs are thermally stable, highly lipophilic and water-insoluble compounds which can induce various toxic influences including immunotoxicty, carcinogenicity adverse effects on reproduction, development and endocrine fuctions. Polybrominated diphenyl ethers or PBDEs, are organobromine compounds that are used as flame retardant. Because of their toxicity and persistence, the industrial production of some PBDEs is restricted under the Stockholm Convention, a treaty to control and phase out major POPs. In this study, PBDEs was measured in various site of Sihwa industrial complex to investigate concentration distribution of POPs. The levels of PBDEs in house dust samples were 0.722~44.024 ng/g-dry. In PBDEs congener, BDE-209 was relatively higher in the all sites. The concentration of BDE-209 measured over 80.0% of total PBDEs. In various site, high molecular PBDEs homologues are measured higher than low molecular.

잔류성유기오염물질(POPs)은 환경에 잔류하며, 먹이 사슬을 통해 축적되고, 인간의 건강과 환경에 악영향을 일으키는 화학물질이다. 잔류성 유기 오염 물질은 열에 안정적이고, 친유화성, 불용성의 물질이며, 생식, 성장 및 내분비 기능에 면역독성 및 발암성 부작용 등 다양한 유해 영향을 일으킬 수 있다. 폴리브롬화디페닐에테르(PBDEs)는 방염제로 사용되는 유기브롬 화합물이다. 독성 및 잔류성으로 인해 일부 PBDE 생산품은 주요 POPs를 관리하고 단계적으로 제한하는 스톡홀름 협약에 의해 제한되었다. 본 연구에서는 잔류성유기오염물질의 농도분포를 조사하기 위해 시화산업단지의 여러 사이트에서 PBDEs를 측정하였다. 하우스더스트 샘플에서 PBDEs의 농도수준은 0.722~44.024 ng/g-dry로 나타났으며, PBDEs 동족체 중 BDE-209가 모든 지역에서 상대적으로 높게 나타났다. BDE-209의 농도는 총 PBDEs의 80.0 % 이상으로 나타났다. 대상 지역의 여러 사이트에서 고분자 PBDEs는 저분자 PBDEs 보다 높게 측정되었다.
