The effect of chronic cement dust exposure on lung function of cement factory workers in sokoto, nigeria

Abstract

ABSTRACT

Effect of Cement Dust Exposure on Lung Function among Residents of Kalambaina Community in Sokoto State, Nigeria

“…21 The findings on pulmonary function parameters (the VC (vital capacity), FVC, FEV 1 , FEV 1 /VC ratio and PEFR values) in the study carried out by Yang 22 and his colleagues are consistent with the findings in this study. The findings by Al -Neaimi 16 and others, 6,17 were also similar to the findings in this study. These studies on cement dust exposure have demonstrated the observation of lower pulmonary function indices and impaired lung function.…”

“…12 A study carried out on the workers of this cement factory in Kalambaina found that cement dust was deleterious to health of the workers. 6,7 The study found the vital capacity and forced expiratory volume for one second percent [FEV 1 %] were found to be significantly lower in the cement factory workers than in the control subjects. The haemoglobin concentration and packed cell volume were significantly lower than those of the control group while the white cell count and platelets were significantly higher in the cement factory workers than in the control group.…”

“…The liver enzymes were not significantly different except for alkaline phosphatase which was significantly lower in the cement factory workers than in the control subjects. 6,7 If these effects were reported in cement factory workers who are aware of the health risks of cement dust and claim to use protective devices, the fate of residents in the host communities, who are unaware of the health risks and use no protective devices should be of great concern. There is need to assess the lung function of these residents.…”

“…Some researchers in Nigeria have studied the effect of chronic exposure to cement dust on the health of cement factory workers and have found cement dust deleterious to health. [6][7][8][9][10][11] Oguntoke and his colleagues in their study in Ewekoro Local Government Area, South-Western Nigeria on both cement factory workers and residents of Ewekoro found that the health profile of the factory workers and some residents of neighbouring communities showed high levels of respiratory and skin infections. 12 A study carried out on the workers of this cement factory in Kalambaina found that cement dust was deleterious to health of the workers.…”

Excessive Exposure to Dust Among Cleaners in the Ethiopian Cement Industry

“…Several cross sectional studies have found high prevalence of chronic respiratory symptoms (7,38,41,(49)(50)(51)(52)(53)(54) and reduction of lung function (7,41,53,(55)(56)(57).…”
