Abstract
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.
본 연구는 상대적으로 농약을 많이 살포하는 고랭지 배추 농작업자를 대상으로 피레스로이드계 살충제의 노출에 영향을 미치는 요인을 생물학적 모니터링을 이용하여 평가하기 위하여 수행되었다. 강원도 고랭지 배추 작업을 하는 농업인을 대상으로 하여 농약 살포 다음날 아침 첫 소변을 받아서 요중 cis-, trans-DCCA, DBCA를 분석하였다. 농약 노출에 영향을 미칠 수 있는 요인으로는 풍속, 살포 위치, 보호구 착용 등을 조사하였다. 통계분석은 Kruskall Wallis로 시행하였다. 분석 결과, 고랭지 배추 작업자는 일반인보다 농약에 대한 노출이 많았으며, 풍속이 낮은 경우에는 살포자가 더 많이 노출되지만, 풍속이 높은 경우에는 살포자와 보조자간의 차이가 없었다.
