In this study, the author measured the frequency of symptoms and/or alterations in respiratory functions in workers of the sour gas refining industry. All workers (n = 62) were employed in the most-exposed units of the Kangan Sour Gas Refinery. The refinery is approximately 250 km east of Bushehr Port along the Persian Gulf. This cross-sectional study involved a comprehensive health questionnaire, standardized clinical examinations by physicians blinded to subjects' symptoms and concerns, and multiple spirometric values. Although gas refinery workers experienced more respiratory symptoms than the 30 controls (i.e., 37.7% vs. 23.3%, respectively), who were matched for age and smoking status, pulmonary function data were not statistically different (p > .05) between the groups. The authors concluded, therefore, that in Kangan Sour Gas Refinery workers there were no respiratory or spirometric values associated with chronic low-dose exposure to sour gas plant emissions, including hydrogen sulfide.
在本研究中，作者测量了酸性气体精炼行业工人的症状发生频率和/或呼吸功能改变情况。所有工人（n = 62）均受雇于坎甘酸性气体精炼厂暴露程度最高的部门。该精炼厂位于波斯湾沿岸布什尔港以东约250公里处。这项横断面研究包括一份全面的健康问卷、由对受试者症状和担忧不知情的医生进行的标准化临床检查，以及多个肺功能测量值。尽管与年龄和吸烟状况相匹配的30名对照组相比，炼油厂工人出现了更多的呼吸道症状（分别为37.7%和23.3%），但两组之间的肺功能数据在统计学上并无差异（p > 0.05）。因此，作者得出结论，在坎甘酸性气体精炼厂工人中，不存在与长期低剂量接触酸性气体工厂排放物（包括硫化氢）相关的呼吸症状或肺功能测量值。
