“…The amount of dust emitted depends on the type of material, the specific operation, the machine characteristics and the working environment [7]. Inhaled wood dusts range from 6% to 75% of the total wood aerosol [8,9]. Wood dust particles enter the human body mainly through the respiratory tract, causing direct toxicity by damaging alveolar, tracheal and bronchial epithelial cells.…”

BackgroundOccupational respiratory diseases are responsible of one-third of all documented work-related deaths. Exposure to wood dust leads to multiple respiratory manifestations including cough, chest pain, asthma and altered lung function. The aim of this study was to assess the level of exposure to wood dust and its respiratory health correlates among woodworkers in Yaoundé.MethodologyThe present descriptive cross-sectional study was conducted in 37 carpentry workshops in the city of Yaoundé. From October 2021 to February 2022. The geographical site selection was purposeful, taking into account areas with large numbers of workers and woodworker shop. Woodworker shops were enumerated and randomly selected. Respiratory manifestations were assessed upon a clinical respiratory examination involving cough, expectoration, wheezing and dyspnea. The force expiratory volume was determined using a dry spirometer. Statistical analyses were performed using IBM SPSS version 23.0 software; tables and graphs were generated using Excel 2013 software. The significance level was set at 0.05.ResultsThe study population was exclusively male, with a mean age of 34.04 ± 11.69 years. With 15.02 ± 12 years of woodwork experience. The respiratory symptoms reported were cough that was productive (41.8%) or dry (33.6%), chest pain (34.4%), dyspnea (41%) and wheezing (15.6%). The lung function decreased among the duration of woodwork experience.ConclusionRespiratory manifestation among woodworkers were reported. And there is a urgent need to implement woodwork safety measures including education on exposure and adherence to protective measure.

The outbreak of COVID-19 has created renewed attention on research and large scale manufacturing of face masks. In the last two decades, usage of face masks for respiratory protection has gained increased importance as a measure to control the maladies and fatalities due to exposure to particulate pollutants and toxic pathogens. Numerous variants of surgical and high-performance respirator masks are available in the market, and yet the fibrous materials science researchers, manufacturers and public health agencies are making concerted efforts towards improvising them with respect to self-sterilisability, facial fit, thermo-physiological comfort, reusability and biodegradability, while maintaining or rather enhancing the filtration efficiency. This review article presents a compendium of materials, design and performance standards of existing face masks, as well as elaborates on developments made for their performance enhancement. The criticality of inculcation of good hygiene habits and earnest compliance to correct mask donning and doffing practices has also been highlighted. This review is expected to make valuable contributions in the present COVID-19 scenario when donning a face mask has become mandatory.

“…Wood dust is classified into three categories: total, inhalable and respirable dust [ 6 ]. The particles with a mass median aerodynamic diameter of 100 μ are inhalable, and those with a mass median aerodynamic of 4 μ which deposit in the lower respiratory tract and interact with alveolar macrophages, are respirable [ 7 ]. It is worth noting that respirable wood dust ranges from 6% to 75% of the total wood aerosol [ 6 , 8 ].…”

Background This study was undertaken to determine the effect of wood dust on the respiratory system and oxidative stress in furniture workers and to determine whether any associations exist between respiratory parameters and oxidative stress. Methods This cross-sectional study was performed on 45 furniture workers and 45 office workers as a reference group in Iran. The NIOSH method 0600 was used to determine the concentration of particulates. The prevalence of respiratory symptoms was estimated via the European Community Respiratory Health Survey (ECRHS) questionnaire. Oxidative stress biomarkers and respiratory parameters were also measured. Results The mean concentrations of respirable and non-respirable dust were found to be 1.51 mg/m 3 and 1.23 mg/m 3 , respectively. Pulmonary function parameters, including forced vital capacity (FVC), forced expiratory volume in the first second (FEV1), FEV1/FVC, and antioxidant capacity biomarkers such as total antioxidant capacity (TAC) and superoxide dismutase (SOD) were significantly lower, while the prevalence of respiratory symptoms, and malondialdehyde (MDA) levels, were significantly higher in the furniture workers than in the reference group. There were significant positive associations between FVC and FEV1 with SOD and TAC. Conclusion The present study results indicated that exposure to wood dust significantly increased respiratory disorders and confirmed the association between lung function parameters and oxidative stress.
