Measurements in ambient air have indicated, that air pollution contains fibrous dusts in various concentration. Moreover it seems to be necessary to get informations of the fiber content in the lungs of men. In this investigation 22 dusts, which were isolated by formamide-methode from lungs, were analysed. Methods of preparation and evaluation of the lung dust of people, which were occupational non-asbestos-exposed, are described. Fiber concentration per mg lung dust lies between 10 X 10(3) and 535 X 10(3). Most of the fibers were shorter than 10 mum. Because of the limitation of the evaluation-technique it was not possible to analyse the fibers with regard to their chemical composition.
对环境空气的测量表明，空气污染中含有不同浓度的纤维状粉尘。此外，获取人体肺部纤维含量的信息似乎很有必要。在这项研究中，对通过甲酰胺法从肺部分离出的22种粉尘进行了分析。描述了对职业性非石棉暴露人群肺部粉尘的制备和评估方法。每毫克肺尘中的纤维浓度在10×10³至535×10³之间。大多数纤维短于10微米。由于评估技术的限制，无法对纤维的化学成分进行分析。
