The results from the labour-hygienic and clinical laboratory studies on working environment and workers engaged in production of polyamide (PAS) and polyacrylnitrile fibres (PAN) are summed up as well as in the production and processing of polyvinylchloride resin, polyurethan, polysterene and glass fibre laminates. The main deleterious factors in those productions are the chemical ones: caprolactam, acrylonitrile,tolyl diisocyanate, vinylchloride, styrene, etc. Noise and microclimate are the other unfavourable on-the-job factors. The concentrations of the toxic substances in the air of the working environment are pointed to be far over MAC, in spite of the new plants. Experiments are reported aiming at the determination of the real exposure of the workers - via individual sample collecting and elaboration of BMAC. The measures for the improvement of the conditions of the working environment in the production of synthetic fibres and plastics are summed up as well as the reduction of occupation risk of the workers.
总结了对从事聚酰胺（PAS）、聚丙烯腈纤维（PAN）生产以及聚氯乙烯树脂、聚氨酯、聚苯乙烯和玻璃纤维层压板生产与加工的工作环境和工人进行的劳动卫生与临床实验室研究结果。这些生产中的主要有害因素是化学因素：己内酰胺、丙烯腈、甲苯二异氰酸酯、氯乙烯、苯乙烯等。噪声和微气候是其他不利的工作因素。尽管有新工厂，但工作环境空气中有毒物质的浓度仍远超过职业接触限值（MAC）。报告了旨在通过个体采样和生物接触限值（BMAC）测定来确定工人实际接触情况的实验。总结了改善合成纤维和塑料生产中工作环境条件以及降低工人职业风险的措施。
