The aerodynamic size of airborne bacteria in pig buildings was normally distributed and overall respirable airborne bacteria ranging between 0.6 and 4.7 [micro]m (stage 3 to stage 6) were estimated to account for about 60% of the total airborne bacteria.
A low-vol impactor [PM.sub.10] (ZUF-Frankfurt, Germany) operated at flow of 9.0 L [min.sup.-1], two cyclones ([PM.sub.2.5] URG-2000-30EH and [PM.sub.1.0] URG-2000-30EH, URG Corporation, USA) operated at flow of 16.7 min [L.sup.-1] and a Sioutas personal cascate impactor (SKC Incorporation, USA) with stages A, B, C and D (aerodynamic size (> 2.5; 1.0-2.5; 0.5-0 1.0; 0.25-0.50; < 0.25 [micro]m) with flow rate of 9.0 L [min.sup.-1] were employed for the sampling.
The central role of cascade impaction in the analytical toolkit for inhaled products is largely attributable to the fact that, unlike all other particle sizing methods, this one provides a mass-weighted distribution based on aerodynamic size for the active ingredient, rather than for the complete formulation.
