Abstract

The residual amount of 160 kinds of pesticide for multi-analysis methods were analyzed in Baechu cabbages throughout the year by GC/MS. We investigated the 160 kinds of pesticide residues in commercial Baechu cabbages monthly from October 2007 to September 2008. Over the 12 months, the residues were detected in the Baechu cabbages harvested and distributed only in July, August, October and November. The residual amounts were 0.01 ppm Bifenthrin, 0.04 ppm Chlorfenapyr, and 0.03 ppm Bifenthrin in July, October, and November, respectively, and 0.01 2 ppm Bifenthrin in August. All residues were below MRL. These results indicate that the commercial Baechu cabbages are comparatively safe from pesticide residues.

연중 시중에서 유통되고 있는 배추에서의 잔류농약에 관한 모니터링을 실시하였으며, 동시 다성분 분석이 가능한 160가지의 농약을 대상으로 하였다. 연중 배추 중 농약의 잔류량을 관찰한 결과 12개월 중 8개월은 잔류농약이 검출되지 않았고, 잔류 농약이 검출된 시기는 7월과 8월, 10월과 11월이었다. 월동배추를 제외한 계절에는 배추의 품질이 나빠, 농약 사용량이 많아지기 때문에, 자연히 농약이 잔류할 가능성이 커지기 때문인 것으로 보인다. 각 농약의 잔류량은 7월, 10월, 11월에는 Bifenthrin 0.01, Chlorfenapyr 0.04, Bifenthrin 0.03 ppm이고, 8월에는 Bifenthrin이 각각 $0.01{\sim}0.02\;ppm$으로 이는 모두 각 농약의 MRL 미만의 양이었다. 따라서 연중 시중 유통배추는 농약 잔류에 대해 상당한 안전성을 확보하고 있다고 볼 수 있다.
