“…Cement is made from limestone, laterites, clay and gypsum; and its composition includes, calcium oxide (lime), aluminium trioxide, silicon dioxide (silica), iron oxide and other impurities. 4 These pollutants have been implicated in many diseases including respiratory abnormalities, genetic disorders, hematological complications, organs and systems failure, vision problems, brain damage and teratogenic effect. 5 Cement dust can cause ill health by inhalation, skin contact or eye contact and the extent of damage depend on the duration of exposure, level of exposure and individual sensitivity.…”

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.

Respiratory Symptoms and Patterns of Pulmonary Dysfunction among Roofing Fiber Cement Workers in the South of Thailand: Phayong THEPAKSORN, et al. College of Public Health Sciences, Chulalongkorn University, Thailand— Objective This study examined the associations between respiratory symptoms and patterns of pulmonary dysfunction of 115 male roofing cement workers compared with 134 unexposed subjects. Methods A cross‐sectional study was conducted. Environmental samplings and spirometry measurements were also collected. Results The exposed workers had higher respiratory dust exposure levels (0.65 mg/m3) compared with the unexposed groups (0.32 mg/m3). The exposed group had significantly higher prevalence than the unexposed group for shortness of breath (OR=2.19). The exposed group also had higher but insignificant prevalence of chronic cough (OR=1.34), chest tightness (OR=1.64), and wheezing (OR=1.89). The ventilatory respiratory function values (FEV1 and FVC) were slightly lower for the exposed group. Conclusion An association between higher cement dust levels and a decline in ventilatory function among roofing fiber cement workers suggests that the respiratory health of roofing cement workers should be protected through policies or work standards.

“…Workers in cement manufacturing workplaces might be exposed to as high as 30.18 mg/m 3 or as low as 0.6 mg/m 3 of respirable dust that are highly dangerous. 30,31 As well, in agricultural environment; exposure to respirable dust varies according to the season and local climate condition. 32 Cement industry and construction workers are exposed to cement dust on a daily basis.…”

Background: Recently, lung cancer representing 5-7% of all cancers in Egypt with unavailable accurate epidemiological data. This study aims to identify characteristics, risk factors and histopathological types of bronchogenic carcinoma among a group of Egyptian patients.Methods: A cross sectional study was conducted on 123 cases of histopathological confirmed bronchogenic carcinoma presented to chest diseases department, Al-Zahraa Hospital, Al-Azhar University, Egypt in the period from July 2013 to May 2017. Statistical analysis of patients’ database was done using SPSS version 17.Results: Male to female ratio was 3.2:1; the majority of cases presented in their fifth (55.3%) and sixth (29.3%) decades of life, and urban: rural residence ratio was 2.1:1. Smoking was the most significant risk factor among 93.5% of cases, among them 65.9% were current smokers, 13.0% were ex-smokers and 14.6% were passive smokers. Occupational exposure to cement dust were reported among 47.2% of cases, 16.3% were farmers, 13.0% were employees, 8.9% were house wives, 8.1% were shoe makers and 6.5% were drivers. COPD was reported among 54.5% of cases. The commonest histopathological types were squamous cell carcinoma (31.7%), adenocarcinoma (30.9%), and large cell carcinoma (26.0%). Adenocarcinoma was the predominant type among females (55.3%), passive smokers (31.6%) and non-smokers (15.8%).Conclusions: Small cell lung cancer and squamous cell carcinoma subtypes were predominant among males, active smokers and workers exposed to cement dust. Adenocarcinoma was the commonest type among females, passive smokers and non-smokers. Conduction of anti-smoking campaigns; reduction of environmental pollution with regulation of occupational exposures to cement dust are recommended.
