Measuring of dust at pig farm
|Cathegory||Publication in specialized journals|
During 2008 the concentrations of volatile dust particles in the form of fractions sized up to 10 sm (PM10) and up to 2.5 sm (PM2.5) were measured in the pig farm building with the nominal capacity of 180 pigs placed in stalls with grids. The abovementioned fractions were measured using the gravimetric method and on-line measurement in 24-hour cycles. Standard and other micro- and macroclimate elements were being recorded at the same time. The mean concentration inside the stable was 502.8 for fraction PM10 and 121.8 sg.m-3, around the stable (= immission) it was 410 and 75.1 sg.m-3. The indicated values, especially the immission values, were subject to a rather significant fluctuation of 19.2 – 58.4%. The concentration consisted of PM10 immissions of 81.5% and 61.7% respectively.
