摘要: The objective was to collect a large dataset on both indoor concentrations and emission rates of particulate matter (PM), make detailed analysis the temporal spatial variations PM, thereby develop measuring strategy for pig fattening facilities. Different PM fractions ranging from 0.25 32 μm were sampled continuously together with environmental parameters (i.e., temperature relative humidity). Sampling position (19 locations) within compartment showed significant effect concentration, but this small compared daily variation over whole period. contribution location variance 6, 4 12% PM1, PM2.5 PM10, respectively. contributed 29, 65 58% concentration variance, while period 65, 31 31% Based these conclusions, facilities is proposed. For one period, consists 5 specific sampling periods 48 h. This offers possibility shorten total time significantly reduce number measurements without loss important characteristics (e.g., peak factors). also allows reconstruction evolution entire
