||Endotoxin exposure and symptoms in wastewater treatment workers
||July 2005, Vol.48, No.1, p.30-39. 38 ref.
||This study investigated endotoxin exposure and work-related symptoms in wastewater treatment workers. Questionnaire on data on symptoms was obtained from 468 employees in 67 sewage treatment plants and personal endotoxin exposure was measured in a sample of workers in three different periods during one year. Endotoxin exposure ranged from 0.6 to 2093 endotoxin units (EU)/m3, the geometric mean exposure being low (27EU/m3). Factor analysis yielded three clusters of correlated symptoms: lower respiratory and skin symptoms, flu-like and systemic symptoms, and upper respiratory symptoms. Symptoms appeared to be more prevalent in workers exposed to endotoxin levels higher than 50EU/m3. A significant dose-response relationship was found for lower respiratory and skin symptoms and for flu-like and systemic symptoms.
