Background : Cement factory workers are exposed to cement dust during their daily work activities. Chronic exposure to cement dust may have adverse effect on the haemopoietic system and the workers would suffer from anemia that may lead to cardiovascular disease. Objective: To assess the effects of exposure to cement dust on hemoglobin concentration and total count of RBC in cement factory workers. Methods : This cross sectional study was conducted in the Department of Physiology, Dhaka Medical College, Dhaka from July 2017 to June 2018. After fulfilling the ethical consideration, 46 apparently healthy male cement factory workers, working in a cement factory for 2 years or more, with age ranging from 20 to 50 years were study group and 46 age, BMI and socioeconomic condition matched apparently healthy male subjects from different areas of Dhaka city were control group. Hemoglobin concentration and total count of RBC were estimated using automated haematology analyzer. For statistical analysis, Unpaired Student’s ‘t’ test and Pearson’s correlation coefficient test were performed. Results: In this study, hemoglobin concentration and total count of RBC were significantly (p < 0.05) lower in study group than those of control group. Hemoglobin concentration was negatively related with duration of cement dust exposure. Conclusions: This study concludes that the cement dust exposure had deleterious effect on hemoglobin concentration and total count of RBC and the duration of exposure to cement dust had an impact on hemoglobin concentration.

Background. Cement dust inhalation is associated with deleterious health effects. The impact of cement dust exposure on the peak expiratory flow rate (PEFR), liver function, and some serum elements in workers and residents near cement factory were assessed.Methods. Two hundred and ten subjects (50 workers, 60 residents, and 100 controls) aged 18–60 years were studied. PEFR, liver function{aspartate and alanine transaminases (AST and ALT) and total and conjugated bilirubin (TB and CB)}, and serum elements{lead (Pb), copper (Cu), manganese (Mn), iron (Fe), cadmium (Cd), selenium (Se), chromium (Cr), zinc (Zn), and arsenic (As)}were determined using peak flow meter, colorimetry, and atomic absorption spectrometry, respectively. Data were analysed using ANOVA and correlation atp=0.05.Results. The ALT, TB, CB, Pb, As, Cd, Cr, Se, Mn, and Cu were significantly higher and PEFR, Fe, and Zn lower in workers and residents compared to controls (p<0.05). Higher levels of ALT, AST, and Fe and lower levels of Pb, Cd, Cr, Se, Mn, and Cu were seen in cement workers compared to residents (p<0.05). Negative correlation was observed between duration of exposure and PEFR (r=-0.416,p=0.016) in cement workers.Conclusions. Cement dust inhalation may be associated with alterations in serum elements levels and lung and liver functions while long term exposure lowers peak expiratory flow rate.

Introduction: Inhalation of suspended particulates in cement plants is one of the most important risk factors for pulmonary and respiratory problems for workers of these factories. The purpose of this study was to investigate the role of physical activity on pulmonary function among cement factory workers. Method: This  cross-sectional descriptive-analytical study was conducted among 82 cement factory workers. They were selected based on the available sampling method and volunteers were included in the study. According to Beck questionnaire, 48 people were categorized in the inactive and 34 in the active groups. Pulmonary function indices included VC, FVC, FEV1, FEV1, to FVC ratio. Furthermore, the forced expiratory flow of 25-75% (FEF 25-75%) and Spirometry were used to determine the pulmonary capacity of workers. Independent T-test was applied for comparing the two groups and SPSS software ver. 23 was run for data analysis. Results: The results showed that VC, FEV1 / FVC, and FEF 25–75% indices in the active group were significantly higher than the inactive group (p /0,000) (p≥0.01) (p≥0.03). ). Moreover,  FVC and FEV1 indices in the active group were not significantly different (p≥ 0.18) (p 14 0.14) from the inactive group. Discussion: Our investigations showed the positive effect of physical activity and exercise on the pulmonary parameters and respiratory function of the cement factory workers. Therefore, these people are recommended to exercise regularly during the week to prevent respiratory and health problems caused by high concentrations of cement dust.
