Abstract

Eight dried ear mushroom products (three domestic and five Chinese products) distributed in Korea were analyzed for 321 residual pesticides, 7 heavy metals, and 3 types of radioactivity. Residual pesticides in the domestic products were not detected. However, chlorpyrifos, isoprocarb, mepiquat chloride, and carbendazim were detected in four Chinese products, all of which were below the allowable residual limit. Among the detected pesticide ingredients, only the residue for mepiquat chloride has been established to be present in ear mushrooms. In the heavy metal test, trace amounts of heavy metals were detected in all samples. However, none of the samples exceeded the allowable residual limits, except for one domestic sample that exceeded the standard value of 0.3 mg/kg for lead. Radioactivity tests confirmed that levels were below the minimal detectable activity value in all samples.

국내 유통 중인 건조 목이 8건(국내산 3건, 중국산 5건)을 수집하여 잔류농약 321종, 중금속 7종, 방사능 3종의 유해물질 잔류성분을 조사하였다. 잔류농약 검사결과 국내산 3건에서는 검출되지 않았으나, 중국산 5건 중 4건에서 Chlorpyrifos, Isoprocarb, Mepiquat chloride, Carbendazim이 검출되었다. 농산물 농약 잔류허용기준에 의하면 목이는 Mepiquat chloride(0.5 mg/kg 이하)만 기준치가 설정되어 있다. 또한 중금속 검사결과는 모든 건조 목이에서 미량의 중금속이 검출되었으나, 기준치 이하로 낮게 나타났다. 다만 국내산 시료 1건에서 납 함량이 기준치(0.3 mg/kg)보다 높게 나타나 정확한 원인 규명을 위해서는 톱밥배지, 지하수, 보관·유통 과정에 대한 추가적인 조사가 필요할 것으로 보여진다. 방사능 조사결과에서는 모든 건조 목이에서 방사능 농도가 MDA값 이하로 불검출 수준으로 나타났다. 국내산과 중국산의 평균 방사능 농도는 요오드(131I)와 세슘(134Cs)은 비슷한 수준으로 나타났으며, 세슘(137Cs)은 국내산보다 중국산에서 다소 높게 나타났다. 방사성 세슘(137Cs)은 버섯류에 잘 농축되는 것으로 알려져 있는데 이번 조사에서는 국내 유통 중인 건조 목이는 방사능에 안전하게 나타났다.
