The incidence of respiratory symptoms and lung function impairments among workers exposed to organic dust aerosols was studied. Respiratory symptoms recorded by questionnaire and lung function were assessed in workers involved with processing organic materials and airborne dust levels were measured at the various workplaces. Workers exposed to organic aerosols demonstrated significantly higher incidences of chronic respiratory symptoms compared with nonexposed referents. Male smokers had higher incidences of many respiratory symptoms compared with nonsmokers. Up to 65% of female and 61.9% of exposed male workers reported acute symptoms which developed during a work shift. Significantly decreased lung function was seen in almost all exposed workers compared with referents. Respirable dust concentrations ranged from 0.12 to 3.50mg/m3. The authors conclude that exposure to organic aerosols may contribute to the development of chronic obstructive lung disease, especially in conjunction with smoking.
