Respirable aerosol concentrations (RACs) were measured during four 24-hour periods in a naturally-ventilated (NV) broiler house and in a mechanically-ventilated (MV) broiler house. Mean daily RACs in the NV house with high air exchange rates ranged from 9 to 15·5 particles/ml compared with 34·9 to 44·1 particles/ml in the MV house where ventilation rates were lower. Mean hourly RACs in the NV house were greatest at sunrise, while in the MV house greatest RACs were found between 10·00 and 16·00 h. Most respirable particles counted had diameters between 1 and 2 μm. Ammonia concentrations were reduced as ventilation air exchange increased in the MV house. © 1989. |
