Abstract

We tested for pesticide residues in 124 samples of 22 different items of imported fruits circulated in Gyeonggido. Total 218 pesticides were analyzed by multi-residue method using gas chromatography/nitrogen phosphorus detector-electron capture detector (GC/NPD-ECD), time of flight/mass spectrometer (TOF/MS), ultra performance liquid chromatography/photo diode array (UPLC/PDA), high performance liquid chromatography/fluorescence detector (HPLC/FLD) and mass spectrometer (LC/MS/MS). The pesticides were detected in 18 fruits samples, ranging 0.003~0.3 mg/kg and no samples had violative residue. The separation test to 14 sample pesticides detected was conducted to monitor the current status of pesticide residues according to the partial characteristic. The pesticides were detected in 14 peels ranging 0.03~1.5 mg/kg and 2 fleshes in less than detection limits. These results indicate that imported fruits are safe when the human takes normally but even the small amount of pesticides is harmful when the human takes it in a prolonged period. Therefore, the pesticide residual amounts of imported friuts should be constantly monitored for food safety.

본 연구는 경기도에서 유통 중인 수입과실류에 대한 잔류농약 분석을 수행하였다. 총 22품목 124건의 시료를 구입하여 GC/NPD-ECD, TOF/MS, UPLC/PDA 및 HPLC/FLD, LC/MS/MS를 이용하여 218종 잔류농약을 동시 다성분 분석법으로 분석한 결과 18건의 과실에서 잔류농약이 0.003~0.3 mg/kg 범위로 검출되었으나 기준초과 시료는 없었다. 과실의 부위별 특성에 따른 잔류농약정도를 알아보기 위해 농약이 검출된 과실류 중 14건에 대하여 분리 실험을 실시하였으며, 그 결과 과피 14건에서 0.03~1.5 mg/kg, 과육의 경우 2건에서 검출한계 미만으로 나타났다. 실험결과 모두 잔류농약허용기준 이내에서 검출되어 정상적인 방법으로 섭취할 경우 위해도는 매우 낮은 수준이었다. 그러나 미량이라도 장기간 섭취시 인체에 유해할 수 있으며, 검출빈도가 높은 성분들이 검출되므로 수입과실에 대한 지속적이고 체계적인 모니터링이 필요하겠다.
