Workers exposed to a variety of wood dusts have been shown to exhibit occupational asthma, lung function deficits, and elevated levels of respiratory symptoms.
Despite the popularity of pine and spruce, the health effects of exposures to these woods have not been extensively investigated.
A study was undertaken to investigate the respiratory health of a group of sawmill workers processing pine and spruce (n=94).
Data collection included a respiratory symptom questionnaire, spirometry, and allergy skin testing.
The sawmill workers were compared with a group of oil field workers from the same geographic area who underwent the same study protocol (n=165).
The results showed that the sawmill workers had significantly lower average values for FEV1 and FEV1/FVC (%), adjusted for age, height, and smoking.
These health effects were noted despite an average concentration of respirable dust of 1.35 mg/m3 (range, 0.1 to 2.2 mg/m3).
These levels are below the present occupational standard. (CHEST 1995 ; 108 : 642-46).
