Objectives Exposure to monoterpenes (alpha-pinene, bêta-pinene and delta3-carene) in joinery shops was studied in Sweden during the processing of Scot's pine, and the acute respiratory effects among the employees were evaluated.
Methods A cross-sectional study of 38 workers was carried out in 4 joinery shops.
The investigation included personal air sampling of monoterpenes, biological monitoring of metabolites of alpha-pinene in the workers'urine, interviews following a standardized questionnaire, and dynamic spirometry.
Results The personal exposure to monoterpenes in the joinery shops was 10-214 mg/m3.
The correlation (correlation coefficient=0.69) between exposure to alpha-pinene and verbenols (metabolites from alpha-pinene) in urine was relatively good.
No acute effects on forced vital capacity or forced expiratory volume during 1 s were detected.
The workers had significantly reduced preshift lung function values when compared with the values of a local reference group, even when smokers and ex-smokers were excluded.
Conclusions Personal exposure to the monoterpenes alpha-pinene, bêta-pinene, and delta3-carene in joinery shops may exceed the present Swedish occupational exposure limit of 150 mg/m3 during the winter season when workroom air is commonly recirculated.
The determination of metabolites of alpha-pinene (verbenols) in urine can be used as an index of exposure to fumes released during wood-treating processes. (...)
