Abstract

Solid-phase microextraction (SPME) with $85{\mu}m$ polyacrylate fiber, coupled to gas chromatography-mass spectrometry was used to analyze the plasticizers contained in balloon samples. The balloons were identified to be made of polyisoprene by IR spectroscopy. The plasticizers extracted from the balloon samples soaked in acetone-added water solvent for an hour were quantified by external standard method using nine kinds of plasticizers. The quantification method was validated for standard plasticizers in the range of $0.25-25{\mu}g/g$. The detection limits were $0.11-0.38{\mu}g/g$ for different plasticizers. The RSDs for the reproducibility of this quantitation method were 3.7-14.2%. A few of balloons included risky level of plasticizer concerned as and endocrine disrupter, and it is necessary to regulate these products.

GC-MS와 연결된 $85{\mu}m$ 폴리 아크릴레이트 fiber의 SPME가 풍선 시료 중에 포함된 가소제를 분석하는데 사용되었다. 풍선은 IR 분광법에 의해 폴리이소프렌으로 만들어진 것으로 판명되었다. 한시간 동안 아세톤이 첨가된 물 용매에서 추출된 풍선의 가소제는 9종류의 가소제가 포함된 외부표준법에 의해 정량 하였다. 정량법은 $0.25-25{\mu}g/g$의 농도범위에서 표준 가소제들에 대하여 유효화 과정을 거쳤으며, 검출한계는 가소제에 따라 $0.11-0.38{\mu}g/g$이었고, 이러한 정량법에 의한 재현성의 RSD는 3.7-14.2%이었다. 이들 풍선 중에는 우려할만한 수준의 환경호르몬성 가소제가 검출되는 제품도 포함되어 있어 이들에 대한 규제의 필요성이 있다.
