Detailed investigations of the environment in asbestostextile industry ("Asbestos produce" plant in the town of Sevlievo) were carried out. The parameters determined were: overall dusting, amount of asbestos in aerosol, its mineral and disperse composition. Data on the degree of dusting in the plant for the period 1960--1976 were analyzed and summarized. Professiograms were elaborated, with chronometry and appraisal of the burden of the work operations. All workers were tested clinically and roentgenologically. The data obtained on the degree of dusting in the different departments were re-calculated as amount of inhaled asbestos, depending on how hard the work is, resp. the pulmonary ventilation. The actual risk of asbestos injury was highest in the carding department, followed by the preparatory and the spinning departments. A distinct correlation exists between the degree of professional risk, determined by the asbestos contaminations, and the clinical and laboratory findings.
对石棉纺织行业（位于塞夫利耶沃镇的“石棉制品”工厂）的环境进行了详细调查。测定的参数有：总粉尘量、气溶胶中的石棉含量、其矿物和分散成分。分析和总结了1960 - 1976年期间该工厂的粉尘程度数据。绘制了职业图谱，并对工作操作的计时和负担进行了评估。对所有工人进行了临床和放射学检查。根据工作强度和肺通气量，将不同部门的粉尘程度数据重新计算为吸入石棉的量。石棉损伤的实际风险在梳理部门最高，其次是准备部门和纺纱部门。由石棉污染确定的职业风险程度与临床和实验室检查结果之间存在明显的相关性。
