Title Pulmonary function abnormalities and airway irritation symptoms of metal fumes exposure on automobile spot welders
Bibliographic information 2006, Vol.49, p.407-416. 38 ref.
Abstract This study investigated the pulmonary function of automobile welders exposed to metal fumes in Taiwan. The all-male cohort consisted of 41 spot welders, 76 arc welders, 71 office workers and 59 assemblers without welding exposure. Inductivity-coupled plasma mass spectrophotometry (ICP-MS) was used to detect zinc, copper and nickel levels in the post-shift urine samples. Demographic data, work history, smoking status and respiratory tract irritation symptoms were gathered by a standard self-administered questionnaire. Pulmonary function tests were also performed. Compared to non-exposed workers, there were significantly higher instances of abnormal forced vital capacity, abnormal peak expiratory flow and restrictive airway abnormalities among spot welders. There was also a significant dose-response relationship of airway irritation symptoms (cough, phlegm, chronic bronchitis) among the spot welders.
