Abstract

The aim of this study was to verify the overloading of greased impaction pre-separators (IPs) in samplers for PM10 and PM2.5. Furthermore, the use of cyclone pre-separators (CPs) as equivalent samplers, which are less vulnerable for overloading, was validated. In the overloading test, the greased plates of IPs were replaced by new ones at different time intervals. Additional validating tests were conducted in different animal houses (pigs and poultry), in a technical lab, and in ambient air. Seventy-five pairs of 24-h measurements, 36 for PM10 and 39 for PM2.5, consisting of results for 1 IP and 2 CPs were obtained in total. The equivalence analysis was performed according to EU prescription. Results from the overloading test showed that measured PM2.5 concentrations notably increased with increasing intervals of replacement of the greased plates. PM10 concentrations were not affected by replacement intervals. Results from the validation tests showed comparable results for PM10 with CP and IP in the whole concentration range. PM2.5 concentrations, however, were significantly higher for IP than for CP in animal houses. At low concentrations in the lab and in the outside air, results were comparable. It was concluded that PM2.5 measurements in animal houses cannot be performed with an IP, because of overloading. A CP seems to give reliable results, both for PM10, as for PM2.5 measurements
