초록

본 연구는 감귤 과수원에서 살균제 difenoconazole의 동력분무기와 원격조종분무기의 위해성 평가 비교를위하여 수행되었다 . 시험농약인 difenoconazole 10% 수화제이었으며 , 2,000배 희석액 , 1,000 L를 동력분무기와 원격조종분무기를 이용하여 살포한 후 신체분위별 시료를 채취하여 GC-MS/MS로 잔류농약을 분석하였다 . 시험농약의정량한계는 5 ng이었으며 , 회수율은 85.7~101.9%이었다 . 잔류농약 분석 결과 , 총 노출량은 동력살포와 원격조종살포각각 14,168.6 및 2,108.8 g이었으며 , 총 검출량은 살포량 대비 0.028 및 0.004%이었다 . 노출량을 바탕으로 산출한difenoconazole의 안전한계는 동력살포와 원격조종살포 각각 55.23과 8.32로 difenoconazole 10% 수화제를 살포할때에 농작업자의 위해도는 모두 낮은 것으로 평가되었으며 , 동력분무기를 이용할 때보다 원격조종분무기를 이용하여살포하였을 때 6.6배 더 안전한 것으로 입증되었다 .

This study was carried out to compare the risk assessment of the stationary power sprayer and the remote-control sprayer of the fungicide difenoconazole in mandarin orchards. Commercial pesticide, difenoconazole 10% WP was diluted 2,000 times. After spraying 1,000 L using the stationary power sprayer and the remote-control sprayer, samples for each body part were collected and pesticide residues were analyzed by GC-MS/MS. The limit of quantitative was 0.005 mg/L, and the recovery rates were 85.7~101.9%. As a result of residual pesticide analysis, the total exposure level was 14,168.6 and 2.108.8 g for power spraying and remote-control spraying, respectively.
And the total detection amount is 0.028 and 0.004% of the spraying amount. The margin of safety of difeno- conazole calculated based on the exposure amount was 55.23 and 8.32 for remote control and power spraying, respectively. When difenoconazole 10% WP was sprayed, the risk assessment of farm workers was evaluated to be low. It has been proven to be 6.6 times safer when sprayed using the remote-control sprayer than the stationary power sprayer.
