Abstract. High concentrations of particulate matter (PM) and noxious gases in swine houses would induce adverse effects on the health of workers and animals. The present study investigated the distributions of PM fractions and ammonia (NH3) in two high-rise houses of nursery and fattening stables in a swine house. The concentrations of total suspended particulate matter (TSP), PM10, PM2.5 and NH3, temperature and relative humidity (RH) were detected in the east, west, front, rear and outside of the stables and the middle at three heights (0.5, 1.0 and 1.5 m). Monitoring was conducted at 2-h intervals from 07:00 h to 19:00 h for 3 d. The results showed that the indoor concentrations of PM and NH3 fluctuated with the start of feeding and opening of the fans. The concentrations of TSP, PM10, PM2.5 and NH3 in nursery were 0.64 ± 0.13 mg/m3, 0.39 ± 0.09 mg/m3, 0.21 ± 0.09 mg/m3 and 12.18 ± 3.36 mg/m3 respectively, and were 0.78 ± 0.20 mg/m3, 0.34 ± 0.10 mg/m3, 0.14 ± 0.06 mg/m3 and 26.70 ± 6.78 mg/m3 for fattening stable. For both stables, PM and NH3 concentrations were higher in the front and middle than that in the rear, and PM concentrations were significant increased during feeding time (P < 0.05).
