Title Exposure to dust, resin acids, and monoterpenes in softwood lumber mills
Bibliographic information July-Aug. 2000, Vol.61, No.4, p.521-528. Illus. 40 ref.
Abstract The objective of this study was to assess exposure to potential respiratory hazards in a large lumber mill processing spruce, pine and fir. Personal samples of inhalable particulate were collected to measure exposure to dust and resin acids (abietic acid and pimaric acid). Passive dosimeters were used to measure exposure to α-pinene, β-pinene, Δ3-carene and other unidentified wood volatiles believed to be monoterpenes. The mean concentration of inhalable particulates was 1.0mg/m3 whereas the mean abietic acid, pimaric acid and estimated wood dust levels were 7.2µg/m3, 0.6µg/m3 and 0.5mg/m3, respectively. The mean values of the monoterpene samples were 0.1mg/m3 for α-pinene, 0.3mg/m3 for β-pinene, 0.1mg/m3 for Δ3-carene and 0.5mg/m3 for the unidentified wood volatiles. Monoterpene exposures were much lower than those observed in other studies conducted in Sweden and Finland. The results highlight the importance of considering the content of airborne particulates in lumber mills as well as potential exposure to wood chemicals.
