Abstract

The objective of this study was to understand the content characteristic of polybrominated biphenyl ethers in indoor household dust. Polybrominated diphenyl ethers (PBDEs) are widely used as additive brominated flame retardants (BFR) in electrical and electronic equipment, and insulation in the indoor environment, and may be released indoors via volatilization or as dusts. The indoor household dust samples were collected from January to December in 2011 and measured for the concentrations, congener profiles and possible sources of PBDEs. The concentrations of 22 congeners of PBDEs (the sum of PBDEs 47, 49, 66, 71, 77, 85, 99, 100, 119, 126, 138, 153, 154, 156, 183, 184, 191, 196, 197, 206, 207 and 209) were 35.22~575.88 ng/g for apartment dust samples and 524.44 ng/g for laboratory dust sample. The eight congeners of BDE-47, 153, 183, 196, 197, 206, 207, and 209 are detected in the more than 1 ng/g. The three congeners of BDE-206, 207 and 209 in all dust samples were detected.

본 연구에서는 전기전자제품에 브롬화난연제로 널리 사용되고 있는 폴리브롬화디페닐에테르가 우리의 생활에서 어떻게 배출되는지 파악하고자 가정에서 발생되는 먼지 시료를 2011년 1월부터 12월까지 채취 분석하여 이성체 함량특성을 조사하였다. 아파트와 실험실에서 채취한 실내 먼지 중 총 22종의 PBDEs (47, 49, 66, 71, 77, 85, 99, 100, 119, 126, 138, 153, 154, 156, 183, 184, 191, 196, 197, 206, 207, 209)를 분석하여 정량한 결과, 아파트 실내 먼지에서 검출된 PBDEs 농도는 35.22~575.88 ng/g으로 나타났으며, 실험실에서 겨울에 채취된 먼지 중에서는 PBDEs가 524.44 ng/g 검출되었다. 분석시료 중 1ng/g 이상 검출된 이성체는 BDE-47, 153, 183, 196, 197, 206, 207, 209 등 8종으로 조사되었으며, 모든 시료에서는 BDE-206, 207, 209 3종의 이성체가 검출되었다.
