  • To evaluate exposure characteristics of the insecticide imidacloprid to apple orchard workers during treatment on orchard fields and evaluate its potential risk using a whole body dosimetry (WBD) method, 1,000-time diluted acephate+imidacloprid 25(20+5)% solutions were sprayed on 10 apple orchard fields in Cheongju with a speed sprayer at a rate of 3,000 L/ha/person, after put on clothes such as inner/outer clothes, personal air pump with a IOM sampler, nitrile glove and mask. Exposure test included mixing, loading and application steps. The test pesticide imidacloprid residues in the collected samples were analyzed with a HPLC-DAD. Recoveries ranged from 81.5 to 108.6% for analytical method validation and from 73.8 to 86.7% for field recovery. Total exposed amounts to mixer/loader and applicator were found to be 0.0014-0.0279% of total applied active ingredient of imidacloprid. Glove exposure of both mixer/loader and applicator was higher than the other parts. Margins of safety of mixer/loader and applicator were calculated to be 97-355 and 46-196, respectively, indicating that exposure risk of imidacloprid to apple orchard workers by spraying with a speed sprayer was very low.

  • 대부분의 농약은 인간에게 해를 미치는 화학물질로 구성되어 있어서 반복 노출된 살포자는 다양한 종류의 상해를 받게 된다. 많은 연구결과들에 의하면 농약살포자가 농약에 노출되는 이유로 방제복의 미착용이 가장 중요한 것으로 보고되고 있다. 세계적으로 적지 않은 농민이 경미하든 심각하든 간에 농약중독으로 추정되는 자각증상을 경험한 바가 있다고 답하고 있다. (중략)

  • The aim of this study were to evaluate the exposure level of pyrethroid pesticide according to spraying machine type. The urinary metabolites of pyrethroid pesticide in apple farmers were analyzed to determine the exposure level of pyrethroid pesticide. The result shows that, the spraying volume was greater in SS sprayer group than in power sprayer group. But multi variate analysis which adjust spraying volume and field area, there were no difference of urinary metabolites between two sprayer machine. To make more accurate model of pesticide exposure, the factors influencing pesticide exposure should be determined and further study should be done.

  • 농약의 직주입 혼합방식은 작업자의 안전에 기여하며 남은 농약은 용기와 함께 수거되어 재사용 되므로 환경보전 및 경제적 이점이 있다. 그러나 주입식 방제기의 분관내 농약혼합액이 노즐에 이르는 시간까지의 유동특성인 지연시간은 농약 살포량에 오차를 유발한다. 본 연구는 이 지연시간이 미치는 실제 살포오차의 정도를 파악하려 시뮬레이션을 행하였다. 시뮬레이션의 결과에 의하면 오차는 상당히 심각한 것으로 판단되었으며 지연시간을 단축하려는 여러 방법을 검토하였다. 분관의 직경을 줄여 유동속도를 빠르게 하거나, 혼입 농약의 양을 일정하게 유지하며 방제속도를 가능한 목표속도에 맞추는 방법 등은 약간의 오차를 줄일 수 있을 뿐이었고, 농약을 각 노즐에 주입함으로써 오차를 최소화할 수 있으나 미소계략의 문제를 내포하였다. 따라서 농도의 변화에 따른 지연시간을 없앤 직주입 총유량 제어방식을 통하여 노즐 배출유량을 방제속도의 변이에 따라 보상하며 비례적으로 농약을 주입하여 농도를 일정하게 유지할 수 있을 것으로 판단된다.

  • This study was conducted to evaluate the use of biological monitoring to determine the factors that influence the effects of exposure to pyrethroid pesticides among highland cabbage farmers. Urine was collected from farmers who was cultivating Chinese cabbage in the relatively highground in Gangwon-do the morning following pesticide application and was analyzed for cis- and trans-3-(2,2-dichlorovinyl)-2,2-dimethylcy-clopropane carboxylic acid (DCCA) and 3-(2,2-dibromovinyl)-2,2-dimethyl cyclopropane carboxylic acid (DBCA). Factors affecting exposure to pesticides, such as wind speed, spraying location, and the use of protective gear, were also investigated. Statistical analysis was performed by the Kruskal-Wallis test. Our analysis indicated that highland cabbage farmers were exposed to a higher level of pesticides than the general public or other types of farmers. When the wind speed was low, workers who sprayed pesticides were exposed to a higher level of pesticides compared to the exposure level in an assistant. However, there was no difference in exposure between the two when wind speed was high.

  • This study was carried out to estimate the risk of pesticide operators who use high toxicological pesticides. The class II (highly hazardous) pesticides registered in korea were 15 products, and 11 products were spray type pesticides at orchard file in 2009. The using information based on the pesticide label and the data searched through survey of actual condition on pesticides were used for calculate the pesticide operator exposure dose. The risk quotients of these pesticides against the pesticides operator were calculated as devide pesticide exposure dose by reference dose which were presented by EFSA (European Food Safety Authority), JMPR (Joint FAO Meeting on Pesticide Residues), and US/EPA (United States Environmental Protection Agency). Omethoate showed the highest risk quotient and the values were 338 and 75 when the operator spray using speed sprayer and motor sprayer respectively. Risk quotients of all class II pesticide were above 1. This result means that the risk potential of these pesticides are very high.

  • This study was performed in order to assess the risk of pesticide operator in korean rice paddy. The amount of exposure was calculated based on the informations of 48 kind of items that are used the form of a spraying in korean rice paddy. The risks of these pesticides were assessed to compare the exposure dosage with AOEL (acceptable operator exposure level) which was released form developed countries. When the operator spraying pesticides using motor sprayer, 17 items showed the risk for operator if the operator have not worn the personal protective equipment (PPE), and 6 items showed the risk for operator if the operator have worn the PPE. These result were indicated that the risk of pesticide operator was very high in korean rice paddy.
