Abstract

Abstract:

Measurement points were set inside and outside the barns to monitor PM2.5(diameter of particulate matter ≤2.5μm), PM10(diameter of particulate matter ≤10μm) and TSP(diameter of particulate matter ≤100μm ) concentrations on a swine farm in Changping, suburb Beijing for a full year（2014-09-30 to 2015-08-29）. Comparison and statistical analysis of the monitoring results were done with data from the Changping national environmental monitoring station. Results showed that the concentration ranges of PM2.5 inside and outside the barns were 23-245μg·m^-3 and 11-372μg·m^-3, respectively, PM10 were 113-1182μg·m^-3 and 25-444μg·m^-3, respectively, and TSP were 334-4396μg·m^-3 and 31-742μg·m^-3, respectively. The concentrations of PM10 and TSP inside the barns were much higher than that outside. The concentration of PM2.5 inside the pig barns was mostly influenced by the atmospheric environment, but the particulate matters larger than 2.5μm mostly came from the breeding process.
