초록

본 연구에서는 소와 조사료로 이용되고 있는 볏짚의 농약잔류량 모니터링 결과 검출된 edifenphos와 tricyclazole에 대해 확률적 접근법을 이용해 축산물 중 잔류하는 농약의 우리나라 국민 전체에 대한 노출량을 예측하고 ADI와 비교한 위해성평가를 수행하였다. 평가 결과 소부산물을 간으로만 섭취할 경우 전체인구의 edifenphos 평균 노출량은 ADI대비 0.027%로 매우 낮았으며 $99%^{th}$에서도 0.034% 수준으로 안전하였다. 연령층 별로 볼 때 부산물의 섭취량이 매우 낮은 1~6세가 가장 안전하였으며 부산물의 섭취가 많은 19~29세의 평균 노출량이 ADI대비 0.04%로 상대적으로 높았으나 이 또한 매우 낮은 수준으로 소부산물 섭취를 통한 edifenphos의 위해성은 모든 연령층에서 낮은 것으로 평가되었다. Tricyclazole은 볏짚에 잔류하는 수준이 낮으므로 간 및 신장을 포함한 소부산물 중 잔류량이 음의 값으로 계산되어, 소부산물 중 농약잔류량을 정량한계의 1/2을 적용하여 점추정으로 평가하였다. 소부산물 섭취에 의한 전체인구의 tricyclazole 평균 노출량은 ADI대비 0.0006%로 매우 낮았으며 $99%^{th}$에서도 0.0007%로 아주 미미한 수준이었다. 연령층 별 tricyclazole의 ADI대비 노출량은 $99%^{th}$에서도 1~2세의 0.0003%부터 19~29세의 0.0013%까지 분포하여 소부산물 섭취를 통한 tricyclazole의 위해성은 모든 연령층에서 매우 낮은 것으로 평가되었다.

The objective of this study was to investigate the exposure assessment of Korean consumers to edifenphos and tricyclazole in cattle product fed the rice straw, using a probabilistic approach. We used tricyclazole and edifenphos residue data in rice straw reported by National Academy of Agricultural Science (NAAS) for the 1998, 1999, 2001 and 2010 monitoring study and National Agricultural Products Quality Management Service (NAQS) for 2009 monitoring study. The mean exposures of edifenphos and tricyclazole for all of Korean consumers were 0.027% and 0.0006% of ADI and $99%^{th}$ percentile exposures were 0.034% and 0.0007% of ADI respectively. The group of 1~6 years old consumers has the lowest exposure of edifenphos and tricyclazole. The group of 19~29 years old consumers has the highest exposure of edifenphos and tricyclazole.
