Abstract
최근 관심이 되고 있는 혈액 중 다이옥신 분석방법을 마련하기 위해 미국 NIST의 혈청 인증표 준물질 1589a를 이용하여, 캐나다, 일본 등 선진국의 혈액 중 다이옥신 분석방법을 비교·검토하고, 우리나라 실정에 적합한 혈액 중 다이옥신 분석방법(안)을 제시하였다. 제안된 분석방법은 추출과정에서 유분 등 지방의 효과적인 제거를 위한 알칼리 분해 추출 후 기존의 다이옥신 전처리방법과 유사한 방법으로 정제하여 두 종류의 컬럼을 사용하는 분석방법이다. 또한, 혈청 인증표준물질과 실제 혈액시료에 제안된 분석방법을 적용한 결과 정량한계는 사염화물(TeCDD/DF) 및 오염화물(PeCDD/DF)이 1 pg/g-lipid,육염화물(HxDD/DF) 및 칠염화물(HpCDD/DF)이 2 pg/g-lipid 그리고 팔염화물(OCDD/DF)이 4 pg/g-lipid이며, 검량용 표준물질은 검출 농도를 고려하여 CSL(0.1~1), CS1/2(0.25~2.5), CS1(0.5~5.0), CS2(2~20) 및CS3(10~100)로 제시하였다.
