Title Acute respiratory symptoms in workers exposed to vanadium-rich fuel-oil ash
Bibliographic information Apr. 2000, Vol.37, No.4, p.353-363. Illus. 32 ref.
Abstract To determine whether occupational exposure to fuel-oil ash may cause respiratory illness, a prospective study was undertaken on 18 boilermakers overhauling an oil-fired boiler and 11 utility worker controls. Subjects completed a respiratory symptom diary five times per day. Daily symptom severity was calculated and respiratory symptom frequency and severity was analysed. Boilermakers had more frequent and more severe upper and lower respiratory symptoms than utility workers, and this difference was greatest during interior boiler work. A statistically significant dose-response pattern for frequency and severity of both upper and lower respiratory symptoms was seen with vanadium and PM10 for lower exposures. However, there was a reversal in the dose-response trend in the highest exposure quartile, reflecting a possible healthy worker effect.
