Abstract

The present study was carried out to assess the dietary exposure and the risk for arsenic (As) and mercury (Hg) through mushrooms intake. Various samples (n = 536) covering 17 kinds of mushrooms were collected from retail outlets and markets in Korea. The contents of As were 0.003 (King oyster) ~ 1.952 (Matsutake) mg/kg in raw mushrooms and 0.015 (Fuscoporia obliqua) ~ 16.95 (Matsutake) mg/kg in dry mushrooms, respectively. The contents of Hg were 0.001 (King oyster) ~ 0.030 (Matsutake) mg/kg in raw mushrooms and 0.004 (Oyster) ~ 0.588 (Matsutake) mg/kg in dry mushrooms, respectively. The mean dietary exposures of As was $0.151{\mu}g$/day, taking 0.005% of provisional tolerable weekly intake (PTWI). The mean dietary exposures of Hg was $0.022{\mu}g$/day, corresponding to 0.071% of PTWI. Therefore, the level of overall dietary exposure to As and Hg for Korean population through mushroom was far below the levels recommended by Joint FAO/WHO Expert Committee on Food Additivies, indicating little possibility of concern.

본 연구에서는 버섯류의 비소 및 수은 함량 실태조사를 통해 우리나라 국민이 식품으로써 버섯을 섭취할 경우의 중금속 위해성을 평가하였다. 국내 유통 버섯류 17개 품목, 536건을 분석하였으며, 비소 함량은 생물버섯의 경우 0.003(새송이)~1.952(송이) mg/kg이었고 건조버섯은 0.015(차가)~16.95(송이) mg/kg이었다. 수은 함량은 생물버섯의 경우 0.001(새송이)~0.030(송이) mg/kg이었고 건조버섯은 0.004(느타리)~0.588(송이) mg/kg이었다. 국내 유통 버섯류의 중금속 함량은 타 문헌과 유사하거나 낮은 수준이었다. 식품으로써 버섯을 섭취할 경우, 전체국민의 비소 노출량은 $0.151{\mu}g$/day으로 위해도는 0.005% 수준이었으며, 수은 노출량은 $0.022{\mu}g$/day으로 위해도는 0.071% 수준이었다. 따라서, 우리나라 국민은 국내 유통되는 버섯에 존재하는 비소 및 수은의 위해성으로부터 안전한 것으로 판단된다.
