Objectives: An on-site study was conducted in order to quantify indoor exposure levels and the emission rate of particulate matter for domestic poultry buildings.
Materials and methods: Three types of poultry building (caged layer house, broiler house, and layer house with manure belt) as classified by mode of manure treatment and ventilation were investigated in this study. Nine sites per each poultry building were selected and visited for measuring exposure levels and emission rate of particulate matter. Total dust and respirable dust among the particulate matter were analyzed based on the weight method. Emission rates were estimated by dividing emission amount, which was calculated through multiplying indoor concentration (mg/m 3 ), by the ventilation rate (m 3 /h), into indoor area (m 2 ) and number of poultry reared in the poultry building.
Results: Mean exposure levels for total dust and respirable dust in the poultry buildings were 3.91 (±1.99) mg/m 3 and 1.99 (±0.89) mg/m 3 , respectively. The emission rates of particulate matter in the poultry buildings were estimated as 4.75 (±1.22) mg head -1 h -1 and 64.39 (±24.95) g m -2 h -1 for total dust and 0.58 (±0.23) mg head -1 h -1 and 7.52 (±2.51) mg m -2 h -1 for respirable dust, respectively. The distribution patterns for total dust and respirable dust were similar regardless of poultry building type. Among poultry buildings, broiler house showed the highest exposure level and emission rate of total dust and respirable dust, followed by layer house with manure belt and caged layer house.
Conclusions: The finding that the broiler house showed the highest exposure level and emission rate of particulate matter can be attributed to sawdust utilized as bedding material, which can be dispersed into the air by movements of the chickens. Thus, a work environmental management solution for optimally reducing dust concentrations is necessary for broiler houses.
