本文报道了烟叶复烤工人受职业危害情况,该厂各车间内空气中烟草尘时间加权平均浓度为12.1～57.9mg/m~3飘尘中游离SiO_2含量在5％左右,霉菌培养以根霉菌为主,108名接触烟草尘无吸烟史,工龄在15年以上的工人中明确诊断烟草尘肺5例,检出率为4.6％,X线表现主要为间质性改变,以不规则形S·t阴影改变为主,肺通气功能轻度损害占14.7％,提示烟草尘对工人健康有一定程度影响,必须引起重视,确定做好防尘工作。烟草尘对工人的危害目前仅有少量极道[3.5]而且均为卷烟工人,为了解烟叶复烤作业工人的职业危害,我们对蚌埠门台子烟叶复烤厂进行调查和研究。
In this paper, we report the occupational hazards of redrying workers in tobacco leaves. The weighted average concentration of tobacco dust in the air of each plant in the workshop is 12.1 ~ 57.9mg / m ~ 3, and the content of free SiO_2 in fly ash is about 5% The main, 108 exposed to tobacco dust non-smoking history, workers over 15 years of age in a clear diagnosis of tobacco pneumoconiosis in 5 cases, the detection rate was 4.6%, X-ray findings were mainly interstitial changes to irregular S t Shadows change mainly, pulmonary ventilation mild damage accounted for 14.7%, suggesting that tobacco dust on the health of workers to a certain extent, we must pay attention to determine the dust-proof work. At present, there are only a few polestorms caused by tobacco dust to workers [3.5] and all of them are cigarette workers. To understand the occupational hazards of tobacco re-baking workers, we conducted a survey and research on the bakeries of the Bengbu Taitai Tobacco Factory.
