| Abstract |
The health effects of exposure to vanadium in fuel-oil ash are not well described at levels ranging from 10 to 500µg/m3. As part of a larger occupational epidemiological study that assessed these effects during the overhaul of a large oil-fired boiler, this study was designed to quantify boilermakers' exposures to fuel-oil ash particles, metals and welding gases, and to identify determinants of these exposures. Personal exposure measurements were conducted on 18 boilermakers and 11 utility workers (controls) before and during a 3-week overhaul. Time-weighted average exposures were significantly higher for boilermakers than for utility workers for ash particles less than 10µm in diameter and for vanadium, nickel and iron. Fuel-oil ash was a major contributor to boilermakers' exposure. Vanadium concentrations sometimes exceeded the 2003 ACGIH threshold limit value. |
