Lung function: occupational exposure to wood dust

Assessment of Respiratory Symptoms among Woodworkers in Jimma Town, Southwest Ethiopia, A Comparative Cross-Sectional Study

“…The present study hypothesis that the unique and endemic of the town with wood and wood products exposes woodworkers to different respiratory disorders which manifested with respiratory sign and symptoms as occupational hazard. Exposure to wood dust is responsible for development of varies respiratory diseases as occupation hazard and affecting about two million workers worldwide [3][4][5][6]. Dusts from the wood and its different components enters into respiratory systems via inhalation to cause respiratory disorders by sensitizing and irritating mucous membrane of airways which are manifested by different sign and symptoms among exposed wood workers [7][8][9][10][11][12][13][14].…”

Ventilatory and Auditory Findings among Workers in Asal’s Furniture Factory at New Damietta City, Damietta Governorate, Egypt

“…The averages of the selected environmental measurements were within the Egyptian maximum permissible limits, except for the noise levels in the woodworking building which were higher than the maximum permissible limits. (15) Table (3) shows that, as regards the ventilatory lung functions measurements among the woodworking group, the means±SD of both measured and percent predicted values of FVC and FEV1 were insignificantly slightly lower than those of the comparison group (p˃0.05). In addition, the means of measured and percent predicted values of FEV1/FVC, PEFR, FEF 25-57% were statistically significantly lower than the comparison group (p≤0.05).…”

“…Wood dust generated occupationally consists mainly of >5µm particles, that's is trapped in the upper respiratory tract. The particles with sub-5µm diameter, that range from 6% to 75% of the total wood aerosol (2) , are particularly hazardous as they infiltrate into the lower respiratory tract through sedimentation and diffusion (3) . Wood dust may give rise to allergic rhinitis, chronic bronchitis, occupational asthma (OA), External allergic alveolitis (EAA) and Chronic Obstructive Pulmonary Disease (COPD) (3) .…”

Workplace and Lung Capacity of Petrol Gas Station Workers in Kendari City

“…Airborne exposures to irritants, dusts, and gases can cause pulmonary function (PF) impairment during high-level acute conditions, as well as prolonged periods of low-dose exposure for workers. For occupations that cause potential uncontrolled exposure to substances known to be associated with PF impairment, respirators may be the principal method for exposure control [11].…”
