本文对某烤烟厂和卷烟厂各主要工种的９０４名烟草作业工人及其作业环境进行了长达１６年的动态观察，结果表明，从卷烟包装工到烤烟厂挂烟工，随着接粉尘浓度逐渐增高和接尘工龄延长，烟草尘肺和０＋患病率均相应升高，接尘水平和烟草尘肺发病之间有一定的接触水平——反应关系。纯烟叶和车间粉尘中游离ＳｉＯ２含量的差异，说明烟草尘肺是以土壤粉尘为主引起的混合性尘肺。卷接和包装工未发现烟草尘肺，包装工０＋患病率仅为２．１２％，故国家现行的烟草粉尘卫生标准（３ｍｇ／ｍ３）是可行的，烟草尘肺是可以预防的。
In this paper, a total of 904 tobacco workers and their operating environment in a major tobacco factory and cigarette factory for 16 years of dynamic observation, the results show that from the cigarette packer to the tobacco factory to stop smoking, with the dust concentration Gradually increased and extended the service life of dust, tobacco pneumoconiosis and 0 + prevalence increased accordingly, the level of exposure to dust and tobacco pneumoconiosis have a certain level of contact between exposure - response. The difference of free SiO2 content in the pure tobacco leaf and the workshop dust shows that the tobacco dust pneumoconiosis is a mixed pneumoconiosis caused mainly by the soil dust. No cigarette pneumoconiosis was found in the coiling and packaging workers. The prevalence of 0+ in packaging workers was only 2.12%. Therefore, the current tobacco dust sanitation standard (3mg / m3) is feasible and tobacco pneumoconiosis can be prevented.
