내분비계 장애물질은 무엇이며, 어떤 종류가 있는 가? | 여러 화학물질들 중 환경호르몬이라 불리는 내분비계 장애물질(endocrine disrupting chemicals, EDCs)은 체내의 생체 리듬 유지와 발달 과정을 조절하는 생체 내 호르몬의 생산, 분비, 이동, 대사, 결합작용 및 배설을 방해하는 유해물질이며, 프탈레이트류(phthalates), 비스페놀 A (bisphenol A), 다이옥신류(dioxin), 알킬페놀류(alkyl phenol), 중금속 등이 있다.7) 그 중 프탈레이트는 플라스틱에 유연성을 증가시키기 위해 사용되는 유기화합물의 한 종류로, 열전도율과 기화성이 높아 환경 속에 쉽게 방출된다. | |
가공식품이란 무엇인가? | 7% 증가한 것으로 보고되었다.2) 가공식품이란 식품 원료에 세척, 탈피, 절단 등 간단히 물리적 조작만을 거치거나 물리적, 화학적 또는 미생물학적 처리를 하여 저장 기간을 연장한 제품 모두를말한다.3) 이러한 가공식품은 식품의 생산, 가공 및조리, 유통과정, 포장재 등에 의해 유해물질이 노출되어 체내로 유입될 수 있으며, 만성적으로 노출되는 경우가 많다. | |
일부 프탈레이트류는 인체에 어떤 영향을 미치는 가? | 일부 프탈레이트류는 미국 환경보호청(environmentalprotection agency, EPA)에서 사람에게 발암 가능한물질(Group B2)로 분류되고 있고, 동물실험에서 생식기계의 기능적·구조적 장애 및 태아의 테스토스테론 감소와 같은 변이원성 및 생식독성을 일으키는것으로 알려져 있다.12) 인체에 있어서는 성 호르몬 수준 저하13), 학령기 아동의 지능 감소14), 복부 비만15,16),어린이의 주의력결핍 과잉행동장애(attention deficit/hyperactivity disorder, ADHD)17) 등과의 연관성이제시되고 있다. 특히 어린이는 성인에 비해 프탈레이트에 노출될 수 있는 경로가 많고, 상대적으로 높은 대사속도를 가지고 있어 프탈레이트 노출에 더취약하다. |
