Abstract |
A study was conducted to evaluate the level of bronchial responsiveness among workers recently exposed to vanadium pentoxide during periodical removal of ashes and clinker from the boilers of an oil-fired power station. A total of 11 male workers and 14 controls were examined 40-60h after the last exposure. None of the subjects in the 2 groups had symptoms of bronchial inflammation or significant airway obstruction. However, bronchial responsiveness, investigated using a methacholine challenge test, was significantly higher in the exposed group. It is suggested that exposure to vanadium increases bronchial responsiveness even without clinical appearance of bronchial symptoms. The possible role of such an increased level of airway responsiveness in the development of chronic obstructive lung disease is discussed. |
