Abstract

Phthalates, known as typical endocrine disruptors, are plasticizers used to soften plastics such as polyvinyl chloride (PVC). Because of their material properties, phthalates are used extensively in the production of toys, flooring, wood processing, detergents, and even cosmetics as lubricants and perfume solvents. Due to their endocrine disrupting effect and other adverse health effects published, recently, phthalates have been regulated in many countries. Besides, in an effort to replace phthalates, several chemical plasticizers such as trioctyltrimellitate (TOTM) and dioctylterephthalate (DIOP) have been used instead of the existing harmful phthalates, and novel alternatives are continuously being developed. Nonetheless, phthalates are still being detected in several plastic products, and the safety of alternatives that are considered safe is being questioned. In this review, we describe the adverse health effects of phthalates, their regulation and the current status of their alternatives.

대표적인 내분비계 교란물질인 프탈레이트의 이용실태, 위해성, 규제현황 및 이를 대체하여 사용되는 대체가소제 및 대체플라스틱소재들의 특성을 정리하였다. 프탈레이트는 대표적인 내분비계 장애물질 중 하나로 경구 또는 호흡과 피부를 통해 체내에 침투해 여성호르몬 및 남성호르몬과 갑상선호르몬이 작용을 교란하는 것으로 알려졌다. 특히, 태아의 발달 저하, 성체의 생식능력 저하, 암 유발 이외에도 신경발달 저하 및 정신질환까지도 프탈레이트 노출과 연관이 있음이 보고되었다. 각종 플라스틱 제품, 안료, 화장품 등 일상생활 곳곳에 광범위하게 사용되던 프탈레이트는 규제가 이뤄짐에 따라 여러 종류의 대체가소제들이 사용되고 있으며 가소제를 사용하지 않는 플라스틱 대체소재들이 개발되고 있다. 이들 대체가소제 및 대체소재들의 내분비 교란 및 위해성이 새로이 제기되고 있으며, 프탈레이트 만큼 구체적으로 안전성 평가가 이뤄지지 않았으므로 결코 안전하다고 할 수 없다. 또한 대체가소제 및 대체소재들의 물성적 한계와 낮은 가격경쟁력은 재고되어야 한다. 본 소고에서는 in vitro, in vivo 및 in silico 시험을 통해 알려진 프탈레이트 대체가소제 및 대체소재들의 안전성 자료들을 정리하여 안전성에 대한 의문을 제기함과 동시에 바람직한 대체재 발굴을 위한 가이드라인를 제시하고자 하였다.
