Abstract

Most countries have the legislation and regulation for POPs control in food. In here, we studied the quantitative analysis of 24 organochlorine POPs (${\alpha}$-HCH 1, ${\beta}$-HCH 2, ${\gamma}$-HCH 3, ${\delta}$-HCH 4, trans-chlrodane 5, 2,4'-DDE 6, ${\alpha}$-endosulfan 7, cis-chlordane 8, 2,4'-DDD 9, endrin 10, ${\beta}$-endosulfan 11, 2,4'-DDT 12, endosulfan sulfate 13, HCB 14, aldrin 15, trans-nonachlor 16, 4,4'-DDE 17, dieldrin 18, 4,4'-DDD 19, cis-nonachlor 20, 4,4'-DDT 21, heptachlor 22, heptachlor epoxide 23 and mirex 24) with GC-ECD. The retention time of analytes were ranged between 19.18 min and 34.69 min, and their peak intervals were over 0.05 min at least. LOQs were ranged 0.003 ~ 0.033 ng/g, and their recovery rates were showed 60.9 ~ 120.8% on the 0.1 ng/g concentration of 24 organochlorine POPs. All tested 30 sundried salts were collected on Korean retailed market, and any analyte was not found in all the samples on LOQ levels.

최근 국내외 환경규제를 강력히 받고 있는 잔류성 유기오염물질(POPs)의 농식품에 대한 잔류 허용기준은 설정되어 있으나, 천일염은 제조특성상 환경으로부터 이들 유해물질의 오염 가능성이 매우 높음에도 불구하고 지금까지 관련 조사 및 연구가 이루어지지 않았다. 따라서, 본 논문에서는 천일염에 잔류 가능한 24종의 유기염소계 POPs(${\alpha}$-HCH 1, ${\beta}$-HCH 2, ${\gamma}$-HCH 3, ${\delta}$-HCH 4, trans-chlrodane 5, 2,4'-DDE 6, ${\alpha}$-endosulfan 7, cis-chlordane 8, 2,4'-DDD 9, endrin 10, ${\beta}$-endosulfan 11, 2,4'-DDT 12, endosulfan sulfate 13, HCB 14, aldrin 15, trans-nonachlor 16, 4,4'-DDE 17, dieldrin 18, 4,4'-DDD 19, cis-nonachlor 20, 4,4'-DDT 21, heptachlor 22, heptachlor epoxide 23 and mirex 24)를 대상으로 GC-ECD(DB-5, $30m{\times}250{\mu}m{\times}0.25{\mu}m$)를 활용한 정량분석을 실시하였다. 24종 POPs 물질의 retention time은 19.18 min의 ${\alpha}$-HCH를 시작으로 34.69 min의 mirex 순서로 검출되었으며, 각각의 peak간 간격은 최소 0.05 min 이상인 것으로 확인되었다. 이들 POPs의 LOQ는 0.003 ~ 0.033 ng/g 범위에서 확인되었고, 0.1 ng/g 수준에서 측정한 회수율은 60.9% ~ 120.8%로 나타났다. 본 연구에서 분석한 모든 천일염 시료에서 이들 POPs 물질이 정량한계 이상 검출된 시료는 없었다.
