The association between wood dust exposure and respiratory disorders and oxidative stress among furniture workers

Abstract

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.

Exposure to Wood dust and its Respiratory Health Effects Among Wood Workers in Yaoundé (Cameroon)

“…Additionally, no vacuum system was employed for dust elimination. Because poor working conditions could increase the risk of respiratory impairment, as the connection between inadequate adherence to recommend wood working regulations and increased dust exposure among workers has been well established in other studies [9]. Previous respiratory diseases such as those identified may contribute to the onset of current respiratory symptoms.…”

“…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.…”

“…The correlation between FVC and FEV1 with SOD and TAC supports the theory that oxidative stress was more likely a mechanism of impaired lung function. 8 Also the study undertaken by Mintz et al states that the LFQ may be effective and appropriate in identifying patients who should undergo spirometry testing. 6 The study does have some limitations to consider.…”

“…Paparan debu serbuk kayu dapat menyebabkan peradangan dan iritasi pada sistem pernapasan manusia. Gejala yang muncul seperti batuk, mengi, bronkitis kronis, sesak dada, dan asma (Kargar-Shouroki et al, 2022). Penyakit yang berisiko tinggi terjadi pada pekerja pabrik mebel ini disebabkan karena perilaku pekerja yang tidak menggunakan alat perlindungan diri utamanya masker saat sedang bekerja (Alvita et al, 2022).…”
