Effect of exposure to grain dust on respiratory system of exposed workers

ABSTRACT

A study was conducted in a factory concerned with storage of grain. The target population were all exposed workers [n= 32]. A control group [n= 32] matched as regards age, sex, socio-economic conditions and with no past or present history of grain dust exposure was examined similarly. The results revealed that exposure to grain dust resulted in an increase in prevalence of respiratory symptoms in the form of rhinitis and sinusitis, and bronchitis. The non-respiratory symptoms were in dermatitis. A significant decrease in lung function test was also found in the of a significant lowering in FEV1.0 / VC% and measured VC/ predicted VC% values. Chest radiographic examination revealed no abnormal findings among all exposed workers
