“…Rice mill personnel are commonly exposed to rice dust flecks encompassing spores, microbes, elements, and endotoxins in workstations. Thus, common workforces of Bangladesh [ 80 ] and India [ 81 ] often suffer respiratory disease from respiratory diseases and poor pulmonary physiology compared to non-exposed individuals (control).…”

Introduction Cement dust emitted during cement manufacture consists of toxic components. Occupational cement dust exposure may cause inflammation in the human body, which may be detected early by observing changes in blood parameters such as red blood cell distribution width (RDW) and mean corpuscular volume (MCV). Objectives The study aims to observe the effect of occupational cement dust exposure on RDW and MCV. Methods This study was performed in the Department of Physiology of Dhaka Medical College, Dhaka, Bangladesh, and a factory in Munshiganj, Bangladesh, from September 2017 to August 2018. Ninety-two participants between 20 and 50 years were included (46 subjects were occupationally exposed to cement dust, and 46 were not exposed to cement dust). A pre-designed questionnaire was used for data collection. An independent sample t-test was used to analyze basic information, such as blood pressure and BMI. The multivariate regression model was used to analyze the effect of cement dust exposure on the study group. The impact of cement dust exposure duration was analyzed using the multivariate regression model. The level of significance was p < 0.05. The statistical analysis was performed using STATA-15 (StataCorp, College Station, TX), and the graphical presentation used GraphPad Prism v8.3.2. Results The cement dust-exposed participants had a significantly higher value of MCV by 1.19 fi (95% CI = 0.02, 4.84; p = 0.049) and a 5.92% increase in RDW (95% CI = 5.29, 6.55; p < 0.001) than that of the control group. Conclusion The study reveals that exposure to cement dust causes significant changes in RDW and MCV. These changes may indicate hemolysis due to inflammation.

BackgroundOccupational health is closely related to harmful factors in the workplace. Dust is the primary contributing factor causing impaired lung ventilation function among employees with dust exposure, and their lung ventilation function may also be influenced by other factors. We aimed at assessing the status and influencing factors of lung ventilation function among employees exposed to dust in the enterprises of the Eighth Division located in the Xinjiang Production and Construction Corps (XPCC), China.MethodsEmployees exposed to dust in enterprises of the Eighth Division located in the XPCC in 2023 were selected as the subjects of this cross-sectional study. Their lung ventilation function indicators were extracted from health examination records, and an on-site electronic questionnaire survey was conducted among them. Binary logistic regression analyses were conducted to evaluate the factors influencing lung ventilation function.ResultsAccording to the fixed value criteria, the abnormal rates of forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC), and FEV1/FVC were 31.6, 1.4, and 0.4%, respectively. The lower limit of normal (LLN) criteria could overestimate the rate of abnormal lung ventilation function. Several factors were related to impaired lung ventilation function, including gender, age, education level, marital status, body mass index (BMI), smoking status, physical activity, the type of dust, industry, enterprise scale, occupation, length of service, working shift, monthly income, and respiratory protection.ConclusionsA relatively low abnormal rate of lung ventilation function was observed among employees exposed to dust in enterprises of the Eighth Division, XPCC, and their lung ventilation function was associated with various factors. Effective measures should be taken urgently to reduce the effects of adverse factors on lung ventilation function, thereby further protecting the health of the occupational population.

Background: Seed processing workers are exposed to dust particles generated during the processing of seeds, which can have adverse effects on their respiratory health. Aim: to estimate the prevalence and patterns of respiratory morbidity among seed processing workers in Hooghly district, West Bengal, India, and to explore their use of respiratory personal protective equipment (PPE). Methods: A cross sectional observational study was conducted in 5 seed processing plants from December 2022 to February 2023. A sample size of 129 workers was selected using probability proportionate to population size to select seed processing plants and simple random sampling to select workers at selected plants. Data on sociodemographic characteristics, occupational profile, substance use patterns, respiratory PPE use, and respiratory symptoms were collected through structured interviews. Spirometry was performed with a hand held tabletop spirometer (RMS Helios 401) to assess respiratory function. Results: 52.7% of participants reported at least one chronic respiratory symptom, while 17.1% had evident respiratory morbidity based on spirometry results, with most having restrictive patterns (10.1%). Multivariable regression analysis revealed that factors associated with respiratory morbidity included increasing work years of exposure [1.10 (1.02 1.18)], irregular use of respiratory PPE [4.36 (1.22 15.57)], and primary or below education level [6.09 (1.38 26.98)]. Conclusion: The study highlights the high prevalence of respiratory symptoms and morbidity among seed processing workers. It emphasizes the importance of implementing effective respiratory protection measures and raising awareness about occupational lung diseases in this industry. Further research and interventions are needed to improve the respiratory health and well being of seed processing workers.
