EVALUATION OF PM10 EMISSION FROM FARROWING AND FATTENING SWINE ROOMS BY CONTINUOUS ON-LINE MEASUREMENTS

In this study, PM10 emission factors were studied in both the farrowing and fattening rooms of a piggery. The following climatic and managerial variables were monitored online, in both rooms, throughout the observation period; temperature and humidity (internal and external), ventilation rate, heating, number and weight of animals and type of feed administration. PM10 concentration was also measured continuously in both rooms, and also at the inlet level of the fattening room, to estimate dust coming from the external environment, using a Haz Dust EPAM 5000 (EDC) sampler which is based on the near-forward light scattering method. The emission factor of particulate matter (PM10) was calculated by taking into account PM10 concentrations both inside and outside the building, and the ventilation rate (air volumes extracted from the stable). Correlations between PM10 concentration and the considered variables were studied. The PM10 emission was estimated at 6.8 mg head-1 h-1 from the farrowing room, and at 12.03 mg head-1 h-1 from the fattening room.
