Title Obstructive pulmonary function defects among Taiwanese firebrick workers in a 2-year follow-up study
Bibliographic information Nov. 2001, Vol.43, No.11, p.969-975. 20 ref.
Abstract In a two-year follow-up study, the pulmonary function of 291 firebrick workers was compared with that of 72 controls. Pulmonary function parameters tested included forced expiratory volume in one second (FEV1), forced vital capacity (FVC), and forced expiratory flow after 50% or 75% of vital capacity has been expelled (FEF50%, FEF75%). Most baseline functions were significantly lower for firebrick workers than in controls. The two-year decreases in FEV1/FVC and FEF50% in the firebrick workers was significantly greater than in controls. FEV1, FEF50%, and FEF75%, also showed a dose-response relationship with job titles. The two-year deterioration in pulmonary functions was the worst in burning work, followed by crushing and moulding. Workers in firebrick manufacturing factories with exposure to silica-containing dusts may develop obstructive pulmonary function defects.
