“…One study conducted on sawmills in India revealed that the spirometer parameters, including FVC, FEV1, FEF25%, slow vital capacity, peak expiratory flow rate, FEF50%, and maximum voluntary ventilation, were significantly lower in sawmill workers than in the reference group 18 . Moreover, decreased values of FVC, FEV1, FEV1/FVC, MEF25, MEF50, MEF75, and MEF2575 among wood dust exposed workers have been documented by Bislimovska et al 8 and Boskabady et al 33 Furthermore, other studies also revealed low level of spirometer values during the study on sawmills workers 7,19,34–36 .

“…According to our study high level of FVC, FEV1, PEF, FEV1/FVC, FEF25, FEF75, and FEF2575 was obtained for a <1-year exposed group, but less in a >20-year exposed group. Similarly, a study operated by Omole et al 34 found that FVC and FEV1 were significantly higher in the 1-5-year group and low in the above 10-year group. Hosseini et al 30…”

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.

“…Brefo [2] posited that sawmill operation is dominated by male than female because women fear to engage in activities that are dangerous and requiring physical strength. Agu et al [18] and Omole et al [36] in agreement with this study reported that most sawmills workers in Nigeria have just secondary school level of education. A greater portion of the respondents in this study affirmed that medical examination was not provided by employer before starting work at sawmill, nor any training provided for the job and no medical service for first aid and treatment were provided by the employer.…”

This study aimed to assess air pollution and health hazards around selected sawmills within Port Harcourt metropolis. The physicochemical parameters of the air at the sawmilling sites were determined using onsite air quality analysers. The microbiological parameters were determined using the settling plate technique and the isolates identified based on their cultural and biochemical characteristics. Results showed that estimates of the monitored physicochemical parameters varied with prevalent human activity, time of exposure and atmospheric conditions. At Rumosi, SO2, VOCs and TSP with a concentration 1.250 ppm, 550.500 ppm, 323.200 µg/m3 respectively exceeded the Federal Ministry of Environment (FMEv) & World Health Organization (WHO) limit irrespective of the atmospheric condition, time and day of sampling, while the temperature, PM2.5, PM10 and NO2 with a concentration of 39.450oC, 209 µg/m3, 348.350 µg/m3, 0.181ppm respectively varied and was within the FMEv acceptable standard. At SARS Road Sawmill 1, VOCs, PM10 and TSP exceeded the FMEv limit while at SARS Road Sawmill 2, SO2, NO2, VOCs, PM10 and TSP exceeded the FMEv limits. Microbiological analysis revealed that the bioaerosols contained 12 bacterial genera (Aeromonas, Citrobacter, Staphylococcus, Micrococcus, Klebsiella, Serratia, Pseudomonas, Proteus, Providencia, Shigella, Enterobacter and Bacillus) and 7 fungal genera (Penicillium, Fusarium, Geotrichium, Cladosporium, Rhizopus and Trichophyton and Aspergillus) with total heterotrophic bacterial count (THBC) and total fungal count (TFC) ranging from 2711-26980 CFU/m3 and 373-12851 CFU/m3 respectively. The study also showed that sawmills within Port Harcourt do not pay much attention to the provision and use of Personal Protective Equipment (PPE), as they were generally not provided. The sawmill workers commonly reported cough and chest pain which they admitted could be associated with their jobs. This study has shown that air around sawmill sites contains inhalable chemical and biological agents which could cause respiratory problems to workers with prolonged exposure and dose response. Sawmill operators should provide and enforce the use of PPE within their facility. It is recommended that sawmill workers and other visitors wear personal protective gadgets in the processing area of the sawmill factories. Further study to relate workers symptoms with emission is recommended.

“…Similar results were obtained by Mbengue et al (2018) and Demissie (2019) who revealed a negative correlation between spirometric parameters (FVC, FEV1, FEF 25-75 %, and PEFR) and duration of work among woodworkers. Also, previous study of Omole et al (2018) reported that sawmill workers exposed to wood dust in Nigeria more than 10 years had a signegative correlation between FEV1 and exposure time to wood dust. Abdel-Rasoul and his co-workers (2017) in a study of health disorders among workers in ceramic industry at Queisna City, prevalence of chest manifestations and decreased spirometric measurements.…”

2020, on 100 woodworkers ernorate. Similar numbers of subjects were chosen randomly from workers' relatives who were never exposed to similar hazards. All participants were interviewed using a predesigned questionnaire. Physical examination and spirometric measurements were performed for them. Environmental study of the workplace was done. Results: The mean concentration of respirable wood dust was 3.61±2.00 mg/m 3 , which is higher cantly higher prevalence of respiratory manifestations e.g. rhinitis, cough, expectoration, wheezes, shortness of breathing, chest pain and asthma (59%, 64%, 51%, 34%, 70%, 4% and 24%; respectively) as well as decreased spirometric measurements compared to the controls. The higher prevalence of respiratory manifestations as well as decreased spirometric measurements were positively correlated with time intensity factor. Conclusion and recommendations: Exposure to wood dust in a concentration more than permissible level has been adversely affecting the respiratory system and causing decrease in spirometric measurements. Regular use of good quality personal
