Title Exposure to wood dust and heavy metals in workers using CCA pressure-treated wood
Bibliographic information Mar.-Apr. 2002, Vol.63, No.2, p.166-171. 24 ref.
Abstract Wood used for construction applications is often treated with chromium, copper and arsenic (CCA). This study examined the airborne concentration and particle size distribution of wood particles, chromium, copper and arsenic at outdoor and indoor construction work. At the outdoor sites, mean total dust concentration, measured using personal filter cassette samplers, was 0.57mg/m3. Indoor wood dust concentrations were significantly greater than those measured outdoors and were job category-dependent. The highest mean breathing zone dust concentration, 49mg/m3, was measured at the indoor sanding operation. Personal impactor sampling demonstrated that the mean total airborne concentration of arsenic, but not chromium or copper, was consistently above recommended occupational exposure levels at the indoor work site, and occasionally at the outdoor work sites. At the indoor sanding operation, the mean total chromium, copper, and arsenic concentrations were 345, 170 and 342µg/m3, respectively. Therefore, current standards for wood dust may not adequately protect workers from the heavy metals present in CCA pressure-treated wood.
