摘要: 1. Endotoxins as components of organic dust may have adverse effects on the respiratory health workers in poultry buildings. The move towards more welfare-friendly housing systems for layers increase worker exposure to air contaminants due use litter. 2. endotoxin concentrations inhalable fraction airborne (below 100 µm) from cage and alternative system houses (on-floor, free range aviaries) were compared under both experimental commercial conditions. 3. concentration was higher aviaries (median: 565 EU/m3, range: 362-1491 EU/m3) than (98 EU/m3 (51-470)). 4. In field conditions, 13 (35 3156 EU/m3) buildings (n = 8, 78-576 EU/m3). It correlated respirable (fraction below 5 µm) temperature inside hen house but no seasonal variation observed. 5. present study emphasises that...
