During 1986-1989, dust levels at workplaces in 19 plants manufacturing or using asbestos products in Poland were measured. Total dust concentrations were determined by the gravimetric method and respirable asbestos fibre concentrations were determined by the phase contrast optical microscope method (PCOM). Air was sampled at the breathing zones of the workers by using Casella personal air samplers. Average respirable asbestos fibre concentrations at the workplaces were from 0.06 fibre/cm3 (control desk operator) to 2.25 fibre/cm3 (spinning machine operator), and the average total dust concentrations were from 0.7 mg/m3 (technicians) to 2.3 mg/m3 (preparatory department workers). Compared with the 1980-1985 period, total dust concentrations were 1.5 times, and respirable asbestos fibre concentrations 2.9 times lower. Considering the obtained data and the analysis of the occupational diseases in workers exposed to asbestos dust during 1983-1988, the national expert group for industrial dusts has suggested that the MAC values for chrysotile dusts be lowered to 1.0 mg/m3 (total dust) and 0.5 fibre/cm3 (respirable fibre).
1986年至1989年期间，对波兰19家制造或使用石棉产品的工厂工作场所的粉尘水平进行了测量。总粉尘浓度采用重量法测定，可吸入石棉纤维浓度采用相差光学显微镜法（PCOM）测定。使用卡塞拉个人空气采样器在工人呼吸区采集空气样本。工作场所可吸入石棉纤维的平均浓度为0.06纤维/立方厘米（控制台操作员）至2.25纤维/立方厘米（纺纱机操作员），总粉尘平均浓度为0.7毫克/立方米（技术人员）至2.3毫克/立方米（筹备部门工人）。与1980年至1985年期间相比，总粉尘浓度降低了1.5倍，可吸入石棉纤维浓度降低了2.9倍。考虑到所获得的数据以及对1983年至1988年期间接触石棉粉尘工人职业病的分析，国家工业粉尘专家组建议将温石棉粉尘的最高容许浓度值降至1.0毫克/立方米（总粉尘）和0.5纤维/立方厘米（可吸入纤维）。
