초록

본 연구는 감귤 과수에서 사용되는 살균제 fluazinam의 동력분무기와 원격조종분무기의 위해성 평가 비교를 위하여 수행되었다 . 시험농약은 플루아지남 50% 수화제이었으며 , 2,000배 희석액 , 500 L를 동력분무기와 원격조종분무기를 이용하여 살포한 후 전신복장법으로 신체부위별 시료를 채취하여 LC-MS/MS로 잔류농약을 분석하였다 .
시험농약의 정량한계는 0.0005 g/ml이었으며 , 회수율은 작업복 88.7~114.7%, 내복 88.9~107.9%, 세척용액 82.3~ 97.7%, 거즈 94.3~102.7% 및 유리섬유필터 79.0~94.9%이었다 . 잔류농약 분석 결과 , 총 노출량은 노지재배에서 동력살포와 원격조종살포 각각 평균 321,278.85 및 595.14 g이었으며 , 시설재배에서 동력살포와 원격조종 살포 각각 평균 173,812.21 및 5,510.16 g이었다 . 총 검출량은 살포량 대비 노지재배에서 0.2570 및 0.0005%이었으며 , 시설재배에서 0.1390 및 0.0044%이었다 . 노출량을 바탕으로 산출한 fluazinam의 안전한계는 노지재배에서 동력살포와 원격조종살포 각각 0.44 및 63.90, 시설재배에서 각각 0.27 및 1.62이었다 . 플루아지남 50% 수화제를 살포할 때에는 농작업자의 위해도는 살포자가 직접살포하였을 때, 모두 위험한 걸로 평가되었으며 , 원격조종살포기로 살포하였을 때, 모두 낮은 것으로 평가되었다 . 노지재배 및 시설재배에서 동력분무기를 이용할 때보다 원격조종분무기를 이용하여 살포하였을 때 143.9배 및 6.1배 더 안전한 것으로 입증되었다 .

The purpose of this study was to compare the results of risk assessment a stationary power sprayer (SPS) and a remote-control sprayer (RCS) using the fungicide fluazinam in mandarin orchards.
Commercial pesticide, fluazinam 50% WP was diluted 2,000 times. After spraying 500 L using the stationary power sprayer and the remote-control sprayer, whole body samples were collected, and analysis of pesticide residues was performed using LC-MS/MS. The limit of quantitative was 0.0005 g/ml, and the recovery rates were outer 88.7~114.7%, inner 88.9~107.9%, washing solvent 82.3~97.7%, gauze 94.3~102.7%, and glass fiber filter 79.0~94.9%. According to the results of analysis of residual pesticide, the total average level of exposure was 321,278.85 and 595.14 g for SPS and RCS in outdoor cultivation, and 173,812.21 and 5,510.16 g for SPS and RCS in green-house cultivation, respectively. The total amount detected was SPS 0.2570% and RCS 0.0005% of the amount sprayed in outdoor cultivation, and SPS 0.1390% and RCS 0.0044% of the amount sprayed in green-house cultivation. Calculation of the margin of safety for fluazinam based on the exposure amount was 0.44 and 63.90 for SPS and RCS in outdoor cultivation, and 0.27 and 1.62 for SPS and RCS in green-house cultivation, respectively. When spraying of fluazinam 50% WP was performed, the results of the risk assessment for farm workers showed a high for the SPS, which was evaluated as low for the RCS. The results demonstrated that use of the RCS was 143.9 and 6.1 times safer in outdoor and green-house cultivation than use of the SPS.
