During a survey of building-related symptoms among 1355 employees working in 19 governmental office buildings in the Netherlands, we measured physical and chemical factors, airborne microorganisms, and endotoxin.
Mechanically ventilated buildings were grouped as « healthy » or « sick » based on symptom prevalence (mean symptom prevalence<15% or =15%). We compared physical, chemical, and microbiological characteristics between mechanically ventilated and naturally ventilated buildings.
Gram-negative rods were found in higher numbers in the « sick » buildings.
The concentration of airborne endotoxin was six to seven times higher in the « sick » buildings than in the « healthy » buildings (254 vs 46 ng/m3) ; it was 35 ng/m3 in naturally ventilated buildings.
