背景-隧道工人暴露在爆破和柴油机废气产生的气体和颗粒中。本研究的目的是评估隧道工人呼吸道症状和气流限制的发生，并与这些调查结果多年的exposure.Methods -二百一十二隧道工人和其他205名重型建筑工人的参考组参加了横断面调查。进行了接触测量，以显示两个职业群体之间的接触差异。采用肺量测定试验和关于呼吸道症状和吸烟习惯的问卷调查。特应性通过多重放射性过敏吸附试验（RAST）确定。对矽肺的影像学征象进行评价。呼吸系统症状和肺功能进行了研究，在多年的曝光和调整吸烟习惯和atopy.Results -与参考科目相比，隧道工人有一个显着的下降，用力肺活量（FVC）%预测和用力呼气容积在一秒（FEV 1）%预测时，与多年的曝光。调整后的FEV 1下降了17英里，每年的隧道工作暴露相比，0.5英里的室外重型建筑工人。隧道工人的呼吸道感染征状亦显著增加。慢性阻塞性肺疾病的患病率：（COPD）是14%的隧道工人相比，8%的参考subjects.Conclusion -暴露于粉尘和柴油机尾气，爆破，钻孔和岩石运输隧道工作中的气体，增加了风险，加速下降FEV 1，呼吸道症状，COPD的隧道工人相比，其他重型建筑工人。
Background - Tunnel workers are exposed to gases and particles from blasting and diesel exhausts. The aim of this study was to assess the occurrence of respiratory symptoms and airflow limitation in tunnel workers and to relate these findings to years of exposure.Methods - Two hundred and twelve tunnel workers and a reference group of 205 other heavy construction workers participated in a cross sectional investigation. Exposure measurements were carried out to demonstrate the difference in exposure between the two occupational groups. Spirometric tests and a questionnaire on respiratory symptoms and smoking habits were applied. Atopy was determined by a multiple radioallergosorbent test (RAST). Radiological signs of silicosis were evaluated. Respiratory symptoms and lung function were studied in relation to years of exposure and adjusted for smoking habits and atopy.Results - Compared with the reference subjects the tunnel workers had a significant decrease in forced vital capacity (FVC) % predicted and forced expiratory volume in one second (FEV1) % predicted when related to years of exposure. Adjusted FEV1 decreased by 17 mi for each year of tunnel work exposure compared with 0.5 mi in outdoor heavy construction workers. The tunnel workers also reported significantly higher occurrence of respiratory symptoms. The prevalence of chronic obstructive pulmonary disease: (COPD) was 14% in the tunnel workers compared with 8% in the reference subjects.Conclusion - Exposure to dust and gases from diesel exhaust, blasting, drilling and rock transport in tunnel work enhances the risk for accelerated decline in FEV1, respiratory symptoms, and COPD in tunnel workers compared with Other heavy construction workers.
