A total of 110 samples of dried agricultural products distributed in Gyeonggi-do were analyzed for 263 pesticides according to multi class pesiticide multiresidue method. Ten types of pesticides were detected in 10 samples. Chlorpyrifos was detected in Ricinus communis leaves, chlorpyrifos, hexaconazole, pyridalyl in Chwinamul (wild aster), diniconazole, isoprothiolane, lufenuron in radish leaves, hexaconazole in Cirsium setidens (Korean thistle), bifenthrin, and chlorothalonil, boscalid, and pyraclostrobin in pepper leaves. The detection rate of pesticides was 9.1%, and among these samples, one was detected over Maximum Residue Limits (MRLs). In the validation study, the values of limit of detection (LOD), limit of quantitation (LOQ), coefficient of determination (R 2 ) and recovery were in the range of 0.002~0.027 mg/kg, 0.006~0.083 mg/kg, 0.9964~1.0000 and 74.8~118.9%, respectively. The Positive List System (PLS) was newly introduced as part of the safety management of residual pesticide in agricultural products in Korea in 2019. With the application of the PLS, if the MRL is not established, 0.01 mg/kg limit is applied uniformly. In spite, these of strengthened residue limits, the MRLs of dried agricultural products are still insufficient. Therefore, this study could be utilized as basic data for the setting of proper MRLs.

A safety survey on Pesticide Residues in Pried Agricultural Products 341 의기준에수분함량을보정한잠정기준이적용된다. 일반적으로세계각국및 Codex Alimentarius Commission (Codex) 에서도대부분원료상태의식품에대하여기준을설정하여관리하고있는데, 원료농산물에잔류된농약은가공되면서대부분의농약이감소되지만건조나농축과정중에는오히려증가되는경우도있기때문에유해성 6,7) 에대한연구를지속적으로해야할필요가있다. 우리나라의경우가공식품의잔류허용기준을설정할때, 가공전 후의농약잔류량변화를비교하여산출한가공계수를원료의기준에곱하여 1일최대섭취량 (Theoretical Maximum Daily Intake, TMDI) 이 1일섭취허용량 (Acceptable Daily Intake, ADI) 의 80% 이하수준이되도록 Codex를참고하여설정한다. Codex에서는세계각 8,9) 국의가공식품에대한자료를토대로국제기준을설정하는데먼저 Food and Agriculture Organization of the United nations (FAO)/World Health Organization (WHO) 합동잔류농약전문가위원회 (Joint Meeting FAO/WHO on Pesticides Residues, JMPR) 가세계각국의자료를검토한후과학적으로증명된기준안을국제식품규격위원회농약잔류분과위원회 (Codex Committee on Pesticide Residues, CCPR) 에제안하고국가간협의를통해최종적으로결정한다 10). 과일과채소는국가별로소비형태가다르고가공계수가표준화되어있지않아지속적으로자료를수집하고있는실정이다. 11) 식품의약품안전처는농약허용물질목록관리제도 (Positive List System, PLS) 를도입했으며 2019년전면시행됨에따라모든농산물에대한농약잔류허용기준이강화되고농약사용에주의가필요하다. PLS란국산또는수입식품에대해잔류허용기준이설정된농약이외에는원칙적으로사용을금지하고일률기준인 0.01 mg/kg으로관리하는제도로원료농산물뿐아니라가공식품에도동일하게적용된다. 건조농산물의경우국내수요증가로잔류농약에대한안전성확보가대두되면서많은농약의잔류허용기준마련이시급히요구된다. 또한, 아직소면적재배작물이많기때문에농약사용에대한계도가지속적으로이루어져야하며, 건조농산물에대한체계적인관리와잔류농약실태파악이필요한상황이다. 이에본연구에서는경기도내에서유통되는건조농산물의잔류농약모니터링을실시하여농약에대한안전성을확보하고향후기준설정을위한기초자료로제공하고자한다.

Jo 등의연 21) 22) 구에따르면 chlorpyrifos의경우저장기간중가장낮은감소율을나타낸농약이며, 분자구조내에 3개의염소원자를가지고있기때문에생물학적분해가어렵고, 다른유기인계살충제들과는달리분해반감기가길어농산물에서자주검출된다고보고된바있다. 최근 3년간유통된농산물에서부적합률이두번째로높은농약이었으며잔류 19) 허용기준이낮아서검출시부적합이될확률이높다. 건취나물, 건곤드레에서검출된 hexaconazole과무시래기에서검출된 diniconazole은 triazole계살균제이다. Hexaconazole은 1,2,4-triazole기를가지는침투성살균제로약이묻지않은부위에도효과가우수하며곰팡이로인한녹병, 흰가루병, 흰비단병등을예방하기위해사용된다. 6,23) 2017 경기도농산물잔류농약통계연보 24) 에따르면 hexaconazole은취나물에서검출빈도가높은농약성분이었으며, 서등 25) 의연구에서건취나물분석결과검출된농약이모두 hexaconazole인것으로보아건조후에도잔류되는농약인것을알수있다. Diniconazole은등록된작물수가적고잔류허용기준이낮아부적합으로판정될확률이높은농약이며, 주로열무에서잔류허용기준을초과하여무속작물에빈번하게사용되고있는것을알수있었다. Diniconazole은살균제이자생장조절제로식물 24) 체내의생장촉진호르몬인지베렐린생합성을억제하는작용을하며, 농산물의상품성을위해적절한크기와모양을유지하고자사용되는것으로판단된다. 26) 건고춧잎에서는 pyraclostrobin, chlorothalonil, boscalid, bifenthrin이검출되었고하나의시료에서여러농약이동시에검출되어김등 27) 의연구결과와일치했다. 고추에는재배시가장문제가되는탄저병예방차원에서 chlorothalonil, pyraclostrobin이자주사용되고있으며 2,28) 그외에동시검출된성분은상용화된혼합제농약사용에기인한것으로판단된다. 본연구에서엽채류에검출된농약들을살펴보면대부분작물에등록되어있지않았고, 유사농산물의최저기준에수분함량을고려한잠정기준을적용했다. 해당작물에는등록되지않았지만유사농산물에등록되어있어사용한것으로판단된다. 또한, 기후변화로인해소면적재배작물은다양해지고있으나병해충방제에사용가능한농약이부족하다는점도원인으로작용했을것이다. 29) 나물류의경우수급용이성, 유통및저장중안전성향상을위해건조기술이끊임없이개발되고있으며, 건조나물의다양한상품화가진행되고있기때문에잔류허용기준설정이시급한것으로생각된다. 건조농산물의잔류농약부적합건조농산물중잔류허용기준을초과한시료는 1 건으로건 피마자에서 chlorpyrifos가 1.22 mg/kg 검출되었고엽채류중최저기준인 0.05 mg/kg 에수분함량을보정한 0.17 mg/kg 이잔류허용기준으로약 7배높게검출되었다. 이를 PLS에적용해보면동일하게부적합이지만 0.01 mg/kg에수분함량을보정하여환산한 0.03 mg/kg 까지만허용되어기준이강화된다. 건취나물에서검출된 chlorpyrifos의경우는 0.25 mg/kg 검출되었고 0.44 mg/kg이기준으로적합이었지만 PLS를적용해보면기준이 0.09 mg/kg 으로부적합으로판정된다. 본연구에서적합이었던검출농약들을모두적용해보면부적합률은약 2.7% 로 3배가량증가하는것을알수있었다. 이처럼 PLS 도입에의해건조농산물의부적합이증가할것으로예상되며가공된농산물의소비가증가함에따라농약의잔류허용기준을설정하여관리하는것이안전성을확보하는데매우중요하다. 요즘은가격만큼이나 30) 품질이중요시되고있으며, 소비자들의요구에상응하기위해서는작물의생산성을향상시키는농약사용이불가피하다. 그러나소비자들이안심할수있도록안전한먹을거리를공급하는것도매우중요하기때문에농약사용에대한양면성이존재한다. 이에농민들이적용대상작물에만농약을사용할수있도록안전사용지침준수에관한지도와교육이꾸준히수행되어야하며, 작물에사용가능한농약의수를늘리고기준을추가로설정하는등현실적인해결책을위한노력이필요하다. 특히농산물의경우건조기준이설정된품목이많지않으므로모니터링자료를토대로새로운기준을제시할수있도록지속적인연구가진행되어야할것이다. 국문요약 본연구에서는건조농산물의잔류농약안전성조사를위해경기도에서유통되는건조농산물 110건을수거하여다종농약다성분분석법으로잔류농약 263종을검사하였다. 조사결과총 10건의시료에서 10종의잔류농약이검출되었으며, 건피마자에서 chlorpyrifos, 건취나물에서 chlorpyrifos, hexaconazole, pyridalyl, 무시래기에서 diniconazole, isoprothiolane, lufenuron, 건곤드레에서 hexaconazole, 건고춧잎에서 bifenthrin, chlorothalonil, boscalid, pyraclostrobin이각각검출되었다. 검출률은 9.1% 였으며, 이중건피마자 1 건에서 chlorpyrifos가잔류허용기준을초과하였고부적합률은 0.9% 로나타났다. 유효성검증실험결과검출한계 (LOD) 는 0.002~0.027 mg/kg, 정량한계 (LOQ) 는 0.006~0.083 mg/kg 으로나타났으며, 결정계수 (R ) 는 0.9964~1.0000으로나타났 2 다. 회수율은전반적으로 74.8~118.9% 로나타났다. 2019 년부터 PLS가시행됨에따라농산물에대한안전성관리가강화되었지만건조농산물의경우잔류허용기준이미비하기때문에본연구는향후기준설정을위한기초자료로제공하고자한다.
