플라스틱 제품 중의 프탈레이트계 가소제 분석
Analysis of Phthalate Esters in Plastic Products

초록
프탈산 에스테르는 PVC에 폭 넓은 유연성과 가공성을 부여하여 연질제품으로써 독특한 용도 확대를 가져온 첨가제이다. 한편, 프탈산 에스테르가 발암성 물질로써 간과 신장의 조직기능장해 및 생식기형을 유발하는 물질로 보고되면서 미국, 영국을 비롯한 선진국에서 인체유해성에 관한 연구가 활발히 진행되고 있다. 특히 3세 미만의 어린이들이 사용하는 완구 및 유아용품의 경우 완구를 씹거나 빨면서 가지고 노는 사이에 완구로부터 어린이의 입을 통해 프탈산 에스테르가 직접 인체로 유입될 수 있으므로 유해성 문제가 심각히 대두되고 있다. 그러나 내분비계 장애물질 대책에 있어 전세계적으로 아직도 이에 대한 검사 및 검출방법 등에 대한 표준화된 방법이 없어 연구결과나 기준 등을 서로 비교하는 것에 어려움이 있다. 따라서 본 연구에서는 국내에 유통되고 있는 플라스틱 제품 9종 55품목을 대상으로 추출용매와 시간을 달리하여 프탈산 에스테르의 함량을 정성, 정량 분석함으로써 최적의 가소제 분석 방법을 확립하고자 한다.
Phthalate esters are additives which give wide usage as soft products due to the fact that these endow a softness and a better process to PVC products. However, active researches about their toxicity toward a human body have been carried out in many advanced countries including the United States and England, since the phthalate esters have been reported as carcinogens to give the functional disorder and genetic malformation of tissues in liver and kidney. Specially, in case of toys for children less than 3 years old, when they are playing with the toys while chewing or sucking, seriously harmful problem may occur by the phthalate esters' inducing directly into a human body through a mouth. Nevertheless, since there is no standard method to evaluate and detect these phthalate esters it has been quite difficult to make a comparison between the results and standards. In this study, we have analysed qualitatively and quantitatively for 55 items of plastic products including infants' toys varying solvents and times for extraction to establish the best analytical method of phthalate esters from PVC materials.
