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.
