In a case-control study of 209 workers from a local railway maintenance and repair workshop, pleuropulmonary lesions were studied on chest radiographs. All workers were known to have been exposed to asbestos fibers of all kinds for a long period of time, but the exposure was light. A "dose index" of every worker was calculated based upon the type of working process and cumulated time spent in the working process. We found a certain dose-effect relationship between asbestos exposure and pleural thickening.
在一项针对当地铁路维修车间209名工人的病例对照研究中，通过胸部X光片对胸膜肺部病变进行了研究。所有工人都长期接触过各种石棉纤维，但接触程度较轻。根据工作流程类型和在工作流程中累计花费的时间，计算了每名工人的“剂量指数”。我们发现石棉暴露与胸膜增厚之间存在一定的剂量效应关系。
