Bisphenol A (BPA) is an endocrine disruptor frequently used in food containers, including epoxy resin and polycarbonates. BPA concentrations were monitored by high performance liquid chromatography (HPLC) under photosensitization of riboflavin (RF), methylene blue (MB), rose bengal (RB), or titanium...

Bisphenol A란 무엇인가? | Bisphenol A(BPA, 2,2-(4,4-dihydoxydiphenyl)propane)는 폴리카보네이트, 에폭시 수지 등 플라스틱 중합체의 단위체로서, 젖병, 전자레인지용기, 음료수 캔 등의 식품 저장용기 제조에 사용되는 물질로(1) 공기, 물, 토양, 식품 및 사람의 세포나 혈액에서도 미량 발견된다(2,3). BPA의 구조는 에스트로겐과 유사하며, 체내에서 정상적인 에스트로겐 작용을 방해하는 내분비교란물질로 작용한다. | |
광분해법은 무엇이 있는가? | 식품이나 환경에서 BPA 함량 저감화를 위해 화학적방법 및 광분해법 등의 다양한 제거방법이 연구되고 있다(6-9). 광분해법으로는 이산화티타늄(titanium dioxide)과 같은 광촉매제(photocatalyst)와 자외선을 조사하는 방법(10)과 과산화수소와 Fe(II)이온, 자외선 조사를 통한 photon-Fenton 반응법 등이 대표적이다(8,11). 최근 Ha 등(12)은 라이보플라빈(riboflavin)이 감광제로 작용 시 가시광선 조사에 의해 BPA 농도가 모델시스템 및 차 음료에서 유의적으로 감소됨을 보고하였다. | |
Bisphenol A는 에스트로겐에 어떤 영향을 주는가? | Bisphenol A(BPA, 2,2-(4,4-dihydoxydiphenyl)propane)는 폴리카보네이트, 에폭시 수지 등 플라스틱 중합체의 단위체로서, 젖병, 전자레인지용기, 음료수 캔 등의 식품 저장용기 제조에 사용되는 물질로(1) 공기, 물, 토양, 식품 및 사람의 세포나 혈액에서도 미량 발견된다(2,3). BPA의 구조는 에스트로겐과 유사하며, 체내에서 정상적인 에스트로겐 작용을 방해하는 내분비교란물질로 작용한다. BPA는 에스트로겐이 관여하는 여러 반응에서 유전적, 비유전적인 독성을 유발시키며(1), 갑상선 호르몬 활성 저해(4) 및 발암 가능성 등도 보고되었다(5). |
