The amount of endotoxin and (1 → 3)-β-D-glucan was determined indoors using four different sampling techniques. Airborne active related dust and floor-agitated dust had a lower proportion of endotoxin than sedimented surface dust. Endotoxin and glucan were related in airborne active related dust. An evaluation of the results in relation to effect data is required before recommendations on sampling methods can be issued.
