- W2024195786 abstract "본 연구는 기준 미설정 국내 유통 농산물 5품목 (상추, 호박, 양상추, 양배추, 쑥갓)의 기준 규격 설정을 위해 모니터링 자료를 확보하고자 전국에서 총 407건의 시료를 수거하여 ICP-MS와 수은분석기를 이용하여 납, 카드뮴, 비소 및 수은의 함량을 분석하였다. 대상 농산물 5품목의 납의 평균 함량은 0.001~0.026 mg/kg, 카드뮴은 0.001~0.018 mg/kg, 비소는 0.001~0.008 mg/kg, 수은은 0.0005~0.004 mg/kg 이었다. 모든 시료의 납, 카드뮴 함량은 채소류의 Codex 허용기준 (엽채류:납 0.3 mg/kg 카드뮴 0.2 mg/kg, 과채류: 납 0.1 mg/kg, 카드뮴 0.05 mg/kg)보다 낮은 수준이었다. 본 연구의 모니터링 결과와 2008년 국민건강영양조사의 식품별 1일 평균섭취량을 근거로 위해평가를 실시한 결과 조사대상 농산물 모두를 1일 평균섭취량으로 섭취한다고 하더라도 납, 카드뮴, 수은의 섭취량은 모두 PTWI 값의 1% 이하의 수준인 것으로 나타났다. 이상의 결과는 조사대상 농산물 5품목의 중금속 오염도와 이들의 섭취에 의한 위해도가 모두 낮은 수준이라는 것을 보여준다. This study was carried out as a survey on the level of lead (Pb), cadmium (Cd), arsenic (As) and mercury (Hg) in 5 items of agricultural products (lettuce, pumpkin, head lettuce, cabbage and crown daisy) for which safety guidelines are not yet established in Korea. The 407 samples were collected from local markets in 9 regional places and the levels of metals were measured by ICP-MS and mercury analyzer. The average levels of Pb, Cd, As and Hg were 0.026, 0.018, 0.008 and 0.003 mg/kg for lettuce, 0.002, 0.001, 0.001 and 0.0006 mg/kg for pumpkin, 0.002, 0.005, 0.001 and 0.0005 mg/kg for head lettuce, 0.001, 0.002, 0.0002 and 0.0006 mg/kg for cabbage and 0.022, 0.014, 0.006 and 0.004 mg/kg for crown daisy. For risk assessment, the daily dietary exposures of Pb, Cd and Hg by intake of these agricultural products were calculated and compared with PTWI (provisional tolerable weekly intake) established by JECFA. The daily dietary exposure of heavy metals by intake of these agricultural products were 0.13, 0.56 and 0.09% of PTWI, respectively. These monitoring results will be utilized as fundamental data for the establishment of Korean standards of Pb, Cd, As and Hg in 5 items of agricultural products and valuable source for DB construction for science-based safety control of heavy metals in foods including agricultural products." @default.
