초록
As domestic meat consumption increases, the broiler production industry has been larger and denser. The concentration of particulate matter (PM) andharmful gases generated is also increasing inside livestock house. However, the current research status of PM exposed to farm workers and the healtheffects are in the early stage. To understand PM concentration affecting workers in the broiler house, field monitoring was conducted according to itssize distributions. Concentrations of PM10, PM2.5, and TD (Total Dust) were monitored using personal air samplers with teflon filter during workingand moving periods considering the ventilation systems of 6 broiler houses. The purpose of this study is to monitor the PM concentration in theexperimental broiler houses operated by forced ventilation system generally used in Korea and to evaluate the regional concentrations through airflowpattern. The PM concentrations were increased from inlet to outlet vents resulting in 1,872 of TD, 1,385 of PM10, and 209 ㎍/㎥ of PM2.5, respectively. The TD and PM10 concentrations were increased when the workers and broilers were moving. Among them, the particle size that occupied the largestamount of PM was 13.75 ㎛. These results suggest that personal protection equipments are important to reduce the health effect from PM inhalation.
