Description: As domestic meat consumption increases, the broiler production industry is becoming larger and denser which make more difficult to control the internal environment. Livestock mortality have been increasing and the concentration of fine dust and harmful gases generated inside livestock housing is also increasing. Considering the aging of farmers, exposure to high concentrations of organic dust generated from broiler house can cause serious health problems for workers such as respiratory diseases, asthma and allergies. Fine dust generated inside livestock housing can be emitted to the outside, causing secondary damage in terms of airborne virus spread and livestock odor. Therefore, the purpose of this study is to monitor the concentration of internal fine dust in forced ventilation broiler houses in Korea and to evaluate the effect of exposure to workers by locations considering the ventilation system. Experimental monitoring was conducted 11 different commercial broiler houses in Jeollabuk-do Korea. The broiler houses vary in size from 231' to 2,200', and each ventilation system is windowless forced ventilation. TSP, PM10, and PM2.5 were measured at three points along the length direction from the inlet to the outlet ventilation openings. The monitorings were conducted for 6 hours at a height of 1.5 m from the floor by using air pump and weighing the filters. Also, dust concentration by particle size was measured by dust spectrometer. The concentrations of fine dust were increased from inlet to outlet vent. And the average dust concentration showed TSP 3,924.2 '/m?, PM10 2,717.9 '/m?, PM2.5 421.4 '/m?. Dust concentration by particle size tends to generate higher concentrations of dust at the time of movement.. Field monitoring results showed that the ventilation system are closely related to fine dust concentration.
