||Respiratory impairment in Brazilian foundry workers exposed to sand
||Feb. 2007, Vol.50, No.2, p.83-91. Illus. 31 ref.
||Workers in the foundry industry are at risk of respiratory diseases due to exposures such as polycyclic aromatic hydrocarbons, pyrolysis degradation products, mineral dust, organic dust, resins and isocyanates. This cross-sectional study evaluated respiratory morbidity among 598 workers of six foundries in Brazil with sand moulding operations. Medical evaluations consisted of a questionnaire on respiratory symptoms and occupational history, spirometry and chest X-rays. Additionally, workers exposed to resins and a control group underwent bronchial provocation tests. Their mean length of exposure of the workers was 10.1 years and the overall prevalence of pneumoconiosis 4.5%. Chronic bronchitis (CB) and X-ray profusion were significantly related to the quartiles of length of exposure. There were significant risks of abnormal FVC and FEV1 with the presence of pneumoconiosis (odds ratios of 4.63 and 3.34 respectively).
