안산 및 수원시에서 유통 중인 다류 19품목(감잎차, 국화차, 녹차, 라벤더차, 로즈마리차, 민들레차, 보이차, 뽕잎차, 수국차, 자스민차, 나미향차(찹쌀차), 메밀차, 쑥차, 연화차, 오룡차, 용정차, 장미차, 철관음차, 화과차)을 대상으로 218종의 농약 잔류실태를 조사하였다. 조사대상 65건 중 19건에서 15종(bifenthrin, bromopropylate, chlorpyrifos, cyhalothrin, cypermethrin, chlorfenapyr, dicofol, endosulfan, fenpropathrin, fludioxonil, fenvalerate, iprobenfos, isoprothiolane, tetradifon, triazophos)의 농약이 검출돼 23.1%의 검출률을 나타냈다. 검출된 농약의 잔류량은 0.01~1.24 mg/kg으로 대부분 잔류허용기준 이하로 나타났으나 보이차(2006 년산) 1건에서 bifenthrin이 기준치(0.3 mg/kg)를 초과한 것으로 나타났다. 검출된 농약 15종에 대한 위해도를 평가한 결과 EDI/ADI 값은 0.0001~0.0844%로 나타나 다류에 존재하는 잔류농약은 안전한 수준인 것으로 평가되었다.
The investigation of 218 residual pesticides for 19 types of tea (persimmon leaf tea, chrysanthemum tea, green tea, lavender tea, rosemary tea, dandelion leaf tea, puer tea, mulberry leaf tea, hydrangea leaf tea, jasmine tea, nuomixiang tea, buckwheat tea, mugwort tea, lotus leaf tea, oolong tea, longjing tea, rose tea, tiehkwanyin tea and huoguo tea) obtained from markets in Ansan and Suwon was carried out to assess the risk for residual pesticides in tea. The detection rate was 23.1 % (19 samples of total 65 tea samples) and the detected pesticides were 15 pesticides, such as bifenthrin, bromopropylate, chlorpyrifos, cyhalothrin, cypermethrin, chlorfenapyr, dicofol, endosulfan, fenpropathrin, fludioxonil, fenvalerate, iprobenfos, isoprothiolane, tetradifon and triazophos. The range of concentrations for the detected residual pesticides was 0.01 to 1.24 mg/kg which showed below their maximum residue limits (MRL), but the residual concentration of bifenthrin in a puer tea showed above the legal limit of 0.3 mg/kg. The result of risk assessment of residual pesticides for the detected 15 samples showed that EDI (estimated daily intake) of the pesticides detected ranged 0.0001~0.0844% of their ADI (acceptable daily intake).
