“…In line with our results, Maritta et al, demonstrated that smoking has a synergistic effect to dust on lung function of tile factory workers (12). In this regard, Attarchi et al reported a signi cant synergistic effect of cigarette smoking and occupational exposures on lung function of rubbery workers (13). These ndings revealed that cigarette smoking has been implicated as a risk factor for respiratory disease among industry workers.…”

Occupational respiratory diseases are the most prevalent occurring work-related diseases that contribute to global health concerns. The present study aimed to assess pulmonary function among detergent powder factory workers. In a cross-sectional study, 305 employees working at a detergent powder company in Semnan, Iran were enrolled. Demographic characteristics, health- and job-related information were recorded using a checklist. Subsequently, spirometer was used at baseline, before and after shift-working for recording respiratory ailments and pulmonary function tests (PFT). According to the results, the mean percentage of all spirometric indices significantly reduced after shift-work including forced vital capacity (FVC) (P < 0.01), forced expiratory volume in one second (FEV1) (P < 0.01), FEV1/FVC ratio (P = 0.038), peak expiratory flow (PEF) (P = 0.13) and forced expiratory flow at 25 and 75% of the pulmonary volume (FEF (25–75)) (P < 0.01). Although the mean percentage of FEV1 significantly improved upon wearing the protective mask (P = 0.014). Moreover, FVC and FEV1 indices were significantly loss in smoking workers than in non-smoking participants (P = 0.005 and P = 0.003, respectively). This study revealed that using effective preventive measures such as masks would be helpful to promote health conditions. However, despite the occupational health programs for preventing and reducing work-related respiratory diseases, these can be considered as a serious threat for detergent powder factory workers that need to apply more control strategies and health assessment.

“…Table summarizes 32 articles describing 30 cross‐sectional studies evaluating the presence of respiratory symptoms and NMRD among workers exposed to rubber manufacturing emisssions . Occupational cohorts ( n = 10 896 workers in total) across studies varied from 34 to 1820 workers, and included facilities from the United States ( n = 14), Sweden (6), India (3), Iran (3), Italy (1), Netherlands (1), Poland (1), and Turkey (1).…”

“…Twenty‐six (87%) of the cross‐sectional studies assessed for tobacco use among workers; 19 (63%) of those studies reported respiratory symptoms or lung function associated with smoking. For example, one study described prevalence of lung impairment among exposed non‐smokers (odds ratio = 3.45, 95%CI, 1.76‐9.50), exposed smokers (12.12, 3.35‐37.87), and non‐exposed smokers (3.48, 1.42‐8.33) compared with non‐exposed non‐smokers …”

Background: Non-malignant respiratory disease (NMRD) cases have occurred among rubber manufacturing workers. We examined exposure to rubber manufacturing emissions as a risk factor for NMRD.Methods: From a systematic literature review, we identified case reports and assessed cross-sectional and mortality studies for strength of evidence of positive association (strong, intermediate, non-significant positive association, none) between exposure to rubber manufacturing emissions and NMRD-related morbidity and mortality, and conducted two meta-analyses. Results:We analyzed 62 articles. We identified 11 cases of NMRD. Nine (30%) of 30 cross-sectional studies and one (4%) of 26 mortality studies had strong evidence. The summary odds ratio and SMR for the cross-sectional and mortality meta-analyses were 3.83 (95% confidence interval [CI], 2.28-6.51) and 0.90 (95%CI, 0.82-0.99), respectively. Conclusion:Available evidence supports rubber manufacturing emissions as a potential risk factor for NMRD-related morbidity. Further investigations with longer follow-up periods and inclusion of short-tenured workers could further define risks for NMRD and identify prevention strategies.

“…Also, the encountered general manifestations of loss of appetite, loss of weight, persistent weakness or fatigability, and bony aches showed a highly statistically significant prevalence among exposed workers when compared with their controls. These general toxic manifestations were attributed to the hazardous exposure to various toxic chemicals involved in the rubber industry such as aromatic amines, carbon black, nitrosamines, phthalates, polycyclic aromatic hydrocarbons, and solvents, in many different processes (Attarchi et al, 2013;Wingren and Axelson, 2007). In the rubber manufacturing industry, light naphtha made of aliphatic hydrocarbon (n-hexane) and aromatic hydrocarbons (benzene, ethyl benzene, toluene, xylene, and cumene) could be used as solvents in the production processes.…”

Objective: For several decades, there has been increasing evidence for excess incidence of lung cancer among workers in the rubber industry. The purpose of this study was to assess the risk of lung cancer occurrence among Egyptian workers involved in the rubber industry using two circulating protein biomarkers. Methods: This study was performed in a rubber manufacturing factory in Shubra El-Kheima region in Greater Cairo, Egypt. Environmental assessment for the suspended particulate matter of size 10 µm (PM10) concentrations was done. Levels of plasma pro-surfactant protein B (pro-SFTPB) and serum high-sensitivity C-reactive protein (HsCRP) were measured among the studied population ( n = 155) who were divided into two groups. The first group included 75 workers exposed to rubber manufacturing process while the control group involved 80 administrative subjects. Results: The levels of PM10 neither exceeded the Egyptian nor the international permissible limits where the highest levels were observed in the mixing department. However, through medical history and clinical examination, it was observed that some general and respiratory manifestations were more prevalent among the exposed group when compared with their controls. Laboratory investigations revealed that the mean values of pro-SFTPB and HsCRP levels among exposed workers were significantly higher than those of the control group. These increased circulating proteins levels were strongly and positively correlated with each other and with the duration of employment of exposed workers. Conclusion: The study results support the conclusion that prolonged occupational exposure to rubber manufacturing process is associated with an elevated risk of lung cancer.
