[Changes in the pulmonary function of factory workers exposure to terephthalic acid].
The pulmonary function was examined in 140 workers exposed to terephthalic acid(TPA) and 70 controls in the same residence area as non-exposure workers. The exposed workers exhibited significant decrease in MVV, PEFR, V75, PEFR/H and V75/H(P < 0.05) in comparison with the controls. The decrease was found to be associated with increased TPA concentration by multiple regression analysis. The results of life table method analysis suggested that there was an exposure level-response relationship between accumulative TAP dust exposure and lower FEV1. According to the results reported here, an exposure limit for TPA dust was proposed to be 4.30 mg/m3.
