Background: A higher incidence of occupational diseases has been reported recently compared to the past years. One of the industries where workers are remarkably exposed to dust is cement industry. Several studies have been conducted to evaluate pulmonary functions and biochemical parameters of workers exposed to cement dust in factories and construction sites, but few were concentrated among loading and unloading workers of warehouses. Hence the present study was undertaken to find out the effect of cement dust among loading and unloading workers of cement warehouses.Methods: This study was conducted among 82 exposed (cement dust) and 82 non-exposed individuals. Frequency of symptoms, biochemical parameters and spirometric values were taken from all subjects. Spirometric parameters recorded were, forced vital capacity (FVC), Forced expiratory volume (FEV1), FEV1/FVC% and Peak expiratory flow rate (PEFR).Results: Out of exposed group, 51.2% had cough, 46.3% had rhinitis 45.2% had breathlessness. FEV1 and FVC showed significant reduction while FEV1/FVC values were normal. No significant changes were seen in renal function tests or liver function tests. Mean value of erythrocyte sedimentation rate (ESR) was found to be significantly increased.Conclusions: Compared to normal healthy adults the loading and unloading workers in cement warehouses showed restrictive lung disease and an increase in ESR representing a non-specific inflammatory change. A continuous bio monitoring of health status must be initiated for these employees and awareness campaigns regarding the exposure and use of standardized protective devices must be mandated.

“…Similar findings have been reported from other studies [ 26 , 47 ] on the association of ambient air pollution and respiratory ill health and also high levels of particulate matter in residents near industrial plants [ 23 , 25 , 48 ]. Both respiratory symptoms and reduced lung functions have been consistently associated with exposure to PM; duration and frequency of exposure tend to be determining factors [ 36 , 39 , 40 , 49 , 50 ]. Exposure to PM has been repeatedly associated with decreased FEV1 in human studies [ 32 , 42 , 51 ].…”

We conducted a panel study to investigate seasonal variations in concentrations of airborne PM2.5 and PM10 and the effects on respiratory health in a community near a cement factory; in Chilanga; Zambia. A panel of 63 and 55 participants aged 21 to 59 years from a community located at the edge of the factory within 1 km and a control community located 18 km from the factory respectively; were followed up for three climatic seasons July 2015 to February 2016. Symptom diary questionnaires were completed and lung function measurements taken daily for 14 days in each of the three climatic seasons. Simultaneously, PM2.5 and PM10 concentrations in ambient air were monitored at a fixed site for each community. Mean seasonal concentrations of PM2.5 and PM10 ranged from 2.39–24.93 μg/m3 and 7.03–68.28 μg/m3 respectively in the exposed compared to the control community 1.69–6.03 μg/m3 and 2.26–8.86 μg/m3. The incident rates of reported respiratory symptoms were higher in the exposed compared to the control community: 46.3 vs. 13.8 for cough; 41.2 vs. 9.6 for phlegm; 49.0 vs.12.5 for nose; and 13.9 vs. 3.9 for wheeze per 100 person-days. There was a lower performance on all lung indices in the exposed community compared to the control; overall the mean FEV1 (forced expiratory volume in one second) and FVC (forced vital capacity) predicted percentage for the exposed was six and four percentage points lower than the control. Restriction of industrial emissions coupled with on-going monitoring and regulatory enforcement are needed to ensure that PM (airborne particulate matter) levels in the ambient air are kept within recommended levels to safeguard the respiratory health of nearby community residents.

“…6 Lime is an alkaline material and corrodes biological tissues; silica is a skin abrasive and also damages the lungs; and chromium causes allergic reactions. 7 Many of the studies 3,4,6,8,9,10 done previously demonstrated the effect of cement dust on respiratory system. These studies found out considerable decline in the lung function parameters due to cement dust inhalation.…”

Hematological parameters are acutely effected by cement dust exposure in construction workers

et al. 2017

Cement dust poses an occupational hazard causing respiratory (owing to its inhalation), dermatological, ocular and hematological problems. The purpose of the current study was to evaluate the effect of occupational exposure of cement dust on hematological parameters in construction workers. Apparently healthy sixty five (65) adult male construction workers aged 25-50 years participated in this study. Three (3.0) ml venous blood samples were collected from each participant for hematological analysis at two different time points, one at 8 AM and second at 4 PM at the end of work shift. Differences in means and test of significance were calculated using paired Student's t-test. The results revealed that post shift samples showed statistically significant increase (p<0.05) in mean total leukocyte count (TLC), lymphocyte %, monocyte % and eosinophil % and statistically significant decrease (p<0.05) in mean hemoglobin, red blood cell (RBC) count, packed cell volume (PCV) and platelet count. The present study confirms that hematological parameters are significantly effected in construction workers which may be attributed to the work atmosphere predominated with cement dust.
