“…We also found lower FEV 1 /FVC values for the workers working for more than 10 years and who were exposed to wood dust at concentrations higher than 4 mg/m 3 and 5 mg/m 3 compared with those exposed to wood dust at lower values. In previous studies, Schlünssen et al [15] found decreases in FEV 1 and FVC values for ex-smoker workers who were exposed to wood dust at higher levels compared with those exposed to wood dust at lower levels while any significant variation was not seen in any pulmonary function parameter for other workers in Denmark. Whitehead et al [34] found lower FEV 1 /FVC values for the workers who were exposed to wood dust at higher values compared with those exposed at lower levels in their study.…”

“…Besides, wood contains many microorganisms (including fungi), toxins and chemical substances and they may significantly affect human health [1,2,[8][9][10]. It is recognised that those agents may cause irritation of oral cavity and throat, tightness of the chest, irritant dermatitis, urticaria, alveolitis, deterioration of pulmonary functions, and a reduction of FEV 1 [1,2,7,[10][11][12][13][14][15][16].…”

Objectives: The aim of this study was to estimate occupational exposure to wood dust in the furniture industry in a minor industrial estate in Bursa/Turkey. Materials and Methods: The study was conducted between October 2006 and May 2007. In this study, a total of 656 persons, 328 woodworkers and 328 controls were included. A questionnaire was used in the study. Physical examination and the pulmonary function tests (MIR-Spirobank G) of the workers were performed. A portable Aircheck 2000 pump was used to collect the specimens of wood dust from the workplaces. NIOSH Method 0500 was employed for the gravimetric measurements of dust. Results: The average dust concentration at the workplace was 2.04±1.53 mg/m 3 . It was reported that 176 of workers (53.7%) had blocked nose while working, 141 (43.0%) had redness of the eyes, 135 (41.2%) had itching eyes and 78 (23.8%) had runny nose. No symptoms were observed in the control group while they were working at the workplace. The mean FEV 1 and FVC values of woodworkers, among both smokers and non smokers, were significantly low, although the FEV 1 /FVC value was high (p < 0.05). An increase both in FEV 1 and FVC values was detected among the woodworkers who had a working period less than 10 years and were exposed to wood dust at concentrations over 4 mg/m 3 compared to the woodworkers who were exposed to wood dust at less than 4 mg/m 3 (p < 0.05). Conclusions: As a result, in this study it was pointed out that the exposure to wood dust adversely influenced the workers respiratory functions. Besides, in this study a question associated with the healthy worker effect that can adversely influence health of workers exposed to wood dust at less than (4 mg/m 3 ) is revealed.

“…The study population is described in detail elsewhere (24,29), but in brief the 1997 study included 54 furniture factories or more than 90% of all furniture workers employed in Viborg County. The study population was workers employed in the woodworking, assembly, or stock departments.…”

“…"Asthma symptoms" were defined if the subject answered yes to ≥1 group A question (physician-diagnosed asthma, current asthma, ever asthma, ever wheezed) and ≥2 group B questions (use of asthma drugs, ever chest tightness, ever wake up with chest tightness, wake up wheezing, morning cough, wake up coughing, wheeze when exposed to cold air or pollen or animals, wheeze when exercise) or ≥2 group A questions (24). "Current asthma" was defined, according to the ECRHS definition, as having an attack of asthma in the last 12 months or use of medication for asthma (31).…”

“…The exposure was mostly to softwood (pine, spruce) and wooden boards. We have reported dose-response relationships between inhalable wood dust concentration and respiratory symptoms (23)(24)(25), acute nasal mucosal swelling (23), increased bronchial hyper-responsiveness (25) and acute decline in lung function (26). Furthermore, we have shown an increased incidence of respiratory symptoms among female woodworkers (27).…”

Wood dust is any particle arising from processing or handling wood. Woods are classified into two broad botanical classifications: hardwood is the common name given to the botanical classification angiosperms, and softwood is the common name given to the botanical classification gymnosperms. Gymnosperms have exposed seeds whereas angiosperms have encapsulated seeds. Although there are more than 12,000 species of trees recorded, most species are deciduous trees or hardwoods, and only about 800 species are coniferous trees or softwoods. This chapter discusses production and uses of wood. Wood use depends on availability. Biologically active organic compounds in wood are described. Wood dust is not a component of the ambient environment except in the vicinity of woodworking operations. Toxicity information is given for populations exposed to wood dust (mill workers, furniture makers, etc.). Diseases studied include nonmalignant lung disease, lung cancer, digestive cancer, and Hodgkin's disease. Wood exposure limits for hardwoods and softwoods are listed.
