Previous studies have failed to demonstrate bronchoconstriction in unselected asthmatics after brief (less than or equal to 1/2-h), controlled exposures to formaldehyde (HCHO). This study was designed to evaluate the acute pulmonary response to 3 ppm HCHO in nine nonsmoking asthmatic volunteers over a more relevant exposure duration (3 hrs). Pulmonary function, nonspecific airway reactivity and symptoms were assessed before and at intervals during the exposure. No significant changes in… CONTINUE READING
