Difference in mass concentration of airborne dust during circular sawing of five wood-based materials

Journal of Wood Science volume 57, pages 149–154 (2011)Cite this article

Abstract

The object of this study was to compare the mass concentration of airborne dust during circular sawing of five wood-based materials: solid sugi (Cryptomeria japonica) lumber, tropical hardwood plywood, softwood plywood, particleboard, and medium-density fiberboard. Specimens were sawn at a constant feed per tooth (0.05 mm) using two saw speeds. The mass concentration of airborne dust of diameter 7.07 μm or less (respirable dust) was measured with a light-scattering dust monitor. The mass concentration showed a log-normal distribution, and the geometric means of mass concentration at saw speeds of 2000 and 3000 rpm were 2.33 and 2.89 mg/m3 for tropical hardwood plywood, 1.13 and 2.84 mg/m3 for particleboard, 0.91 and 2.28 mg/m3 for medium-density fiberboard, 1.09 and 1.38 mg/m3 for softwood plywood, and 0.32 and 0.66 mg/m3 for sugi lumber. The mass concentration for all five wood-based materials increased with the revolution speed of the circular saw.
