合成纤维和聚氯乙烯粉尘属合成的有机粉尘。随着合成纤维工业和合成塑料工业的迅速发展,以及对有机粉尘的深入研究,发现长期吸入合成纤维和聚氯乙烯粉尘均可引起尘肺。近来国外陆续有一些报道。我国生产合成纤维和塑料有近20年的历史,产量不断增加,接触这类粉尘的工人也不少。为了做好有机尘肺的防治工作,现根据国外一些资料,对合 Synthetic fiber and polyvinyl chloride dust is a synthetic organic dust. With the rapid development of the synthetic fiber industry and synthetic plastic industry, as well as in-depth study of organic dust, it was found that long-term inhalation of synthetic fibers and polyvinyl chloride dust can cause pneumoconiosis. Recently there are some foreign reports. The production of synthetic fibers and plastics in China has a history of nearly 20 years and the output is constantly increasing. There are also quite a lot of workers exposed to such dust. In order to do a good job in the prevention and treatment of organic pneumoconiosis, are based on some foreign information, the match
