Effect of cement dust on lung function of adult cement loaders in Benin City, Nigeria

Cement is one of the important construction materials used for housing and infrastructure development. It is made from a mixture of clay and limestone that is calcined in kiln. The aim of this research is to investigate the effect of cement dust on lung function of adult cement loaders in Benin City using a total of 60 apparently healthy male and female subjects divided into two groups (experimental and control) of thirty subjects each between the ages of 25-40 years after ethical clearance. Anthropometric and Spirometry measurements were carried out on all subjects and data appropriately documented. Results obtained show reduction in the forced vital capacity of the experimental group(3.0L and 1.0L) compared to the control(1.0L).The forced expiratory volume in one second was reduced for the experimental group compared to the control(3.2L/Second and 1.0L/second respectively).The peak expiratory flow rate of the experimental group were reduced well when compared to the control (5.0L and 0.5L respectively).The results were statistically significant (P<0.05), hence cement loaders are advised to wear protective gadgets.Keywords: Cement, Lung function, Spirometry, Peak Expiratory flow rat
