研究了119名焊工和90名对照者的呼吸症状、肺活量测定、用力呼气流量和N闭合量试验，这些人在年龄、身高和吸烟习惯方面相匹配。问卷调查结果表明，呼吸道症状在焊工中更为普遍。21名不吸烟的焊工在一天或一周内没有发现可归因于焊接的测量变量的短期变化。与对照组相比，不吸烟和不吸烟的焊工肺闭合容积和闭合容量（即闭合容积+残余容积）显著增高，总肺活量和N曲线心源性振荡幅度显著降低，而吸烟者之间无差异。焊工的这些发现可能是由于焊接烟尘颗粒沉积在周围的小气道或肺泡中。
Respiratory symptoms, spirometry, forced expiratory flows and the N closing volume test were studied in 119 welders and 90 controls, matched with respect to age, height and smoking habits. Results of a questionnaire indicated that respiratory symptoms were more prevalent in the welders. No short-term changes of the measured variables during the day or week attributable to welding were found in 21 nonsmoking welders. Compared to the controls, closing volume and closing capacity (i.e., closing volume + residual volume) were significantly higher, and total lung capacity and the amplitude of the cardiogenic oscillations in the N curve were significantly lower in the welders who were nonsmokers or exsmokers, whereas there were no differences among smokers. These findings in welders may be attributable to deposition of welding fume particles in peripheral small airways or alveoli.
