유통 식약공용농산물 중 비의도적 유해물질 오염도 조사 = Investigation of Unintentionally Hazardous Substance in Commercial Herbs for Food and Medicine

다국어 초록 (Multilingual Abstract)

This study was performed to investigate the contamination levels of heavy metals(such as lead, cadmium, arsenic and mercury) and aflatoxin(such as B1, B2, G1 and G2) in commercial herbs for food and medicine. The concentrations of the heavy metals were measured by the ICP-MS and a mercury analyzer. The aflatoxins were analyzed by a HPLC-florescence coupled with photochemical derivatization. The detection ranges of the lead, cadmium, arsenic and mercury were found to be 0.006~4.088 ㎎/㎏, 0.002~2.150 ㎎/㎏, ND~0.610 ㎎/㎏ and ND~0.0139 ㎎/㎏ respectively. Among the total samples, the 3 samples(2.6%) were not suitable for the specification of cadmium by the MFDS(Ministry of Food and Drug Safety). The 13 samples of the total 117 samples were aflatoxin positive(11.1%). The amount of aflatoxin G1 was 0.7834 ㎍/㎏ in the Puerariae Radix and aflatoxin G2 were 0.3517 ㎍/㎏, 0.4881 ㎍/㎏ in two samples of the Glycyrrhizae Radix et Rhizoma, respectively. The aflatoxins B2 and G1 were simultaneously detected in the 10 Angelicae Gigantis Radix. The detection ranges of aflatoxins B2 and G1 were 0.2324~1.0358 ㎍/㎏ and 0.7552~1.6545 ㎍/㎏ respectively in Angelicae Gigantis Radix. The results of the current study suggest that continuous monitoring is needed for the proactive management of commercial herbs for food and medicine safety.
