“…These results are consistent with the studies of other researchers [ 2 , 11 , 17 , 27 , 29 , 44 ]. Mandryk et al [ 45 ] conducted a study of 105 wood workers (with an average age of 38 years and 9 years of work experience) and concluded that the mean values of lung function parameters (VC, FVC and FEV1) were significantly lower in the exposed group.…”

“…These results are in line with those of a previous study conducted by authors on respiratory effects of exposure to bioaerosols [ 42 ]. In some studies of wood workers, the prevalence of respiratory symptoms in the exposed group was higher than that of the reference group [ 2 , 17 , 25 - 27 ]. The results of those studies are consistent with the present study.…”

“…Previous studies have shown a significant association between inhalation of wood dust and an increased prevalence of respiratory symptoms [ 2 , 17 , 25 - 27 ] and decreased lung functional capacity, as manifested by reduced peak expiratory flow (PEF), forced vital capacity (FVC), and FEV1 stands for forced expiratory volume in the first second [ 2 , 7 , 17 , 25 - 29 ]. For instance, Osman & Pala [ 29 ] showed that occupational exposure to wood dust was associated with nasal congestion (53%), redness of the eyes (43%), itchy eyes (41%), and rhinorrhea (23%), in addition to decreased FVC and FEV1 values.…”

OBJECTIVESThe possible adverse respiratory effects of airborne pollutants in sawmills have not been thoroughly investigated in Iran. Additionally, the extent to which workers are exposed to this organic dust and its associated bioaerosols has not been extensively quantified. Likewise, the predominant bacterial and fungal species associated with wood dust have not been characterized. The present study was undertaken to address these issues.METHODSOne hundred male individuals exposed to wood dust and 100 unexposed male subjects were investigated. They completed a standardized respiratory symptom questionnaire and underwent spirometry testing. Additionally, airborne concentrations of respirable and inhalable dust particles, bacteria, and fungi were measured.RESULTSThe mean concentrations of inhalable and respirable dust particles, bacteria, and fungi were found to be 2.44, 6.76 mg/m3 , 756.38, and 299.15 colony-forming units/m3 , respectively. The predominant Gram-negative bacteria in the sawmills included the Pseudomonadaceae, Klebsiella pneumoniae, and Rhinoscleromatis spp., and the predominant fungi consisted of the zygomycetes and Aspergillus spp. Respiratory symptoms were significantly more prevalent among exposed workers. Significant cross-shift decrements were noted in some pulmonary function parameters. Similarly, pre-shift spirometry results indicated that some pulmonary function parameters were significantly lower in the exposed group.CONCLUSIONSExposure to wood dust and its bioaerosols was associated with significantly higher prevalence of respiratory symptoms and both acute (i.e., partially reversible) and chronic (i.e., irreversible) decrements in the functional capacity of the lung. Additionally, the characterized bioaerosols did not differ significantly from those isolated in other parts of the world.

“…This points to a restrictive type of abnormality as supported by the previous studies like Mahamood NM, Noertjojo HK and Schlunssen. [17][18][19] Significant reduction in PEFR in study group compared to the control group shows that there is an element of obstruction along with restrictive abnormality. FEF 25-75 shows small airway disease.…”

Background: There has been an increase in proportion of workers suffering from occupational diseases compared to past. Only limited studies have been conducted to evaluate the pulmonary functions of carpenters, exposed to wood dust. Hence the present study was undertaken to find out any functional impairment in carpenters due to their occupational environment.Methods: Study was done in 300 subjects who were divided into two groups of 150 each. One group comprised carpenters with minimum 5 years exposure to wood dust. Other group comprised matching healthy subjects who served as controls. Pulmonary function parameters were recorded from all subjects. Parameters recorded were SlowVital Capacity (SVC), Forced Vital Capacity (FVC), Forced Expiratory Volume in 1 second (FEV1), and Peak Expiratory flow Rate (PEFR). ‘Knudson and Collagens’ standard reference values for south Indians were used here for interpretation. Statistical analysis of the data of study subjects and the controls were done by using student’s ‘t’ test. The level of significance was fixed as 5%.Results: A statistically significant reduction in SVC, FVC, FEV1and PEFR was seen in the study group compared to control group. FEV1/FVC was less than 80% of the predicted values in 8% of the study population. Seventeen percentage of the study population had less than 80% of predicted value of both FEV1 and FVC with normal FEV1/FVC.Conclusions: Lung functions of carpenters show statistically significant reduction compared to normal healthy adults. This could be due to their exposure to wood dust.

Background and Aims: Occupational exposure to wood dust leads to lung function abnormalities that are prominent causes of morbidity and disability of sawmill workers. The adverse respiratory effects of wood dust in sawmills have not been studied thoroughly in Bangladesh. This study aimed to investigate the effect of wood dust on the respiratory health of sawmill workers compared to controls as well as to determine the association of wood dust-exposing effects with inflammatory blood biomarkers, such as immunoglobulin E (IgE), erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP).Methods: This cross-sectional study included 100 sawmill workers from 25 distinct sawmills in various areas of Tangail, Bangladesh as well as 100 healthy volunteers who were adopted as a control group. Questionaries' survey and pulmonary function tests were performed face to face. Furthermore, after performing lung function tests, blood was drawn for further IgE, ESR, and CRP analyses.Results: Respiratory symptoms including breathlessness (32%), coughing (39%), sneezing (43%), chest tightness (30%), and itching (40%) were significantly higher in sawmill workers compared with control. Besides, sawmill workers' exposure to wood dust revealed a significantly lower level of spirometry parameters (forced vital capacity [FVC], FVC (%), forced expiratory volume in 1 s [FEV1], FEV1 (%), peak expiratory flow [PEF], PEF (%), FEV1/FVC (%), FEF25, FEF75, and FEF2575) compared with control and these spirometry parameters decreased with the increasing length of service. Moreover, a significantly higher level of IgE was observed in sawmill workers (290.90 ± 39.49) than in the control (120.95 ± 23.00).The high level of IgE suggests that the lower pulmonary function may be linked to allergic responses to wood dust among sawmill workers.
