This study was carried out to determine lung function and respiratory and non-respiratory symptoms among men and women exposed to dust emitted from crushing of granite rocks and to compare them with control men and women not exposed to any known air pollutant. The sites were the granite rock crushing industries in old Netim, Akamkpa Local Government Area of Cross River State, Nigeria. Respirable dust level was higher in the dust-emitting sites (1.087±0.243mg/m 3 ) than in the control areas (0.099± 0.007 mg/m 3 ; p 1 % were significantly lower in the dust-exposed group than their control group. (p 1 , FVC and PEFR) thus, suggesting restrictive lung defect among the exposed workers. Lung function indices correlated negatively with duration of service of the granite industry workers. The incidence of the major respiratory symptoms viz: unproductive cough, chest pain, catarrh and dyspnoea among the test group were higher (p Key words: Lung function, Granite, Dust, Symptoms Nigerian Journal of Physiological Sciences Vol.19(1&2) 2004: 41-47
