Abstract

The purpose of our paper was to investigate the migration level of 4,4'-MDA(4,4'-methylenedianiline), 2,4-TDA(2,4-toluenediamine), aniline, acrylonitrile and methylmeth acrylate from plastic cookwares into food simulants and to evaluate the safety of each monomers. The test articles for monomers were PA (polyamide) items for 4,4'-MDA, 2,4-TDA and aniline, PU (polyurethane) items for 4,4'-MDA, ABS (acrylonitrile-butadiene- styrene) items for acrylonitrile, and acrylic resin items for methylmethacrylate. All the article samples of 321 intended for contact with foods were purchased in domestic market. 4,4'-MDA, 2,4-TDA and aniline were analyzed by LC-MS/MS (liquid chromatography -tandem mass spectrometer), acrylonitrile by GC-NPD (gas chromatography-nitrogen phos phorus detector) and methyl methacrylate by GC-FID (gas chromatography-flame ionization detector). The migration level of monomers were within the migration limits of Ministry of Food and Drug Safety (MFDS). As a result of safety evaluation, our results showed that the estimated daily intake (EDI, mg/kg bw/day)s were $2.39{\times}10^{-9}$ and $1.20{\times}10^{-9}$ for 4,4'-MDA and 2,4-TDA of PA, $4.32{\times}10^{-9}$ for acrylonitrile of ABS and $2.27{\times}10^{-7}$ for methylmethacrylate of acrylic resin. Reference Dose (RfD, mg/kg bw/day) of acrylonitrile and tolerable daily intake (TDI, mg/kg bw/day) of methacrylate were established respectively as 0.001 by EPA (US Environmental Protection Agency) and as 1.2 by WHO (World Health Organization). When comparing with RfD and TDI, the EDIs of acrylonitrile and methylmethacrylate accounted for $4.32{\times}10^{-4}%$ and $1.89{\times}10^{-5}%$ respectively.

국내 유통 중인 총 321건의 폴리아미드, 폴리우레탄, ABS, 아크릴 수지 재질 식품용 기구 중 이행우려가 있는 모노머인 4,4'-메틸렌디아닐린, 2,4-톨루엔디아민, 아닐린, 아크릴로니트릴 및 메틸메타크릴레이트에 대하여 이행량을 조사하고 안전성 평가를 실시하였다. 83건의 폴리아미드, ABS 및 아크릴 수지 재질 식품용 기구 검체에서 현행 식품용 기구 및 용기 포장 공전상의 용출규격 이하인 4,4'-메틸렌디아닐린, 2,4-톨루엔디아민, 아크릴로니트릴 및 메틸메타크릴레이트가 이행되었다. 이행량 결과를 토대로 안전성 평가 시나리오에 적용하여 4,4'-메틸렌디아닐린, 2,4-톨루엔디아민, 아크릴로니트릴 및 메틸메타크릴레이트의 EDI를 산출한 후 TDI와 비교하여 위해도를 평가하였다. EDI는 폴리아미드 재질 기구의 4,4'-메틸렌디아닐린과 2,4-톨루엔디아민의 경우 각각 $2.39{\times}10^{-9}$, 및 $1.20{\times}10^{-9}mg/kg\;bw/day$, ABS 재질 기구의 아크릴로니트릴의 경우 $4.32{\times}10^{-9}mg/kg\;bw/day$, 아크릴 수지 재질 기구 메틸메타크릴레이트의 경우 $2.27{\times}10^{-7}mg/kg\;bw/day$이었다. ABS 재질 기구 이행 아크릴로니트릴의 위해도는 RfD 대비 $4.32{\times}10^{-4}%$ 수준이었고, 아크릴 수지 재질 기구 이행 메틸메타크릴레이트의 위해도는 TDI 대비 $1.89{\times}10^{-5}%$ 수준이었다. 결론적으로 검토된 평가 항목들의 위해도는 TDI 대비 $4.32{\times}10^{-4}%$와 $1.89{\times}10^{-5}%$에 불과한 것으로 조사되어 안전한 수준인 것으로 사료되었다. 이러한 결과들은 앞으로 기구 및 용기 포장의 안전관리를 위한 과학적인 근거자료로 이용될 수 있을 것으로 판단된다.
