The present paper provides the health examination result of 185 workers exposed to the grain dust and the investigation monitoring of the working-place.

本文对接触谷物粉尘的185名作业工人,进行健康检查和劳动卫生学调查.在现场测定308份样品中,原粮车间粉尘浓度高,游离二氧化硅含量13.4~38.5%.接尘组中慢性支气管炎检出率明显高于对照组(X~2=8.9,P<0.01),有随工龄增高趋势.肺功能以混合性障碍为主.X线检查提出尘肺样改变标准.检出率10.2%(19例)”以不规则阴影和细网为主的弥散性间质纤维化为特征.谷物粉尘中既有无机尘,也含有机尘,应属于混合性粉尘.

In order to provide scientificbasis for revising the hygiene stan-dard of dust,with the epidemiolo-gic method,we gathered and ana-lysed the 18 years'longitudinal dataof Chengzihe Coal Mine,Jixi. The result showed that it isavailable to use the 20 years dura-tion as a observation duration in stu-dying the relationship between theincidence of anthracosilicosis andthe dust exposure concentration.When we continued observing till the26th year,it showed that at mostonly 0.6 percent degree I anthraco.silicosis occurred. It proved that the concentra-tion of dust exposure to coal con-tained 10-20 percent free SiO_2 andcountry rock mixed dust is 9.5mg/m~3 averagely,if one exposed to suchcoal dust for 18 years,anthracosi-licosis might not occur to him. we suggested that it is suitableto revise the hygiene standard ofcoal dust which contains 10-20 per-cent SiO_2 as 8-9 mg/m~3.

为修订粉尘卫生标准提供依据,用流行病学方法对鸡西城子河煤矿18年动态观察资料整理分析,结果表明,在研究探讨煤矽肺发生与接触浓度的动态观察可以20年作为观察期限;持续观察至26年最多只有0.6‰Ⅰ期煤矽肺发生。并证明,接触含游离si0_21O~20%的煤、围岩混合性粉尘浓度平均为9.5mg/m~3,持续18年可不出现煤矽肺,建议含游离siO_210~20%的煤尘卫生标准修订为8~9mg/m~3为宜。

The dust hazards in feather processing plant were investigated. The dust was of mixed type containing not only feather organic components, but also a lot of impurities. The content of free silica(SiO_2), being depended on the amount of impurity, amounted averagely to 2.3% in feather, yet 41.9% in impurity. The maximal concentration of dust reached to 446.67mg/m~3, The action of free silica might be the main cause of feather worker pneumoconiosis.

The dust hazards in feather processing plant were investigated. The dust was of mixed type containing not only feather organic components, but also a lot of impurities. The content of free silica(SiO_2), being depended on the amount of impurity, amounted averagely to 2.3% in feather, yet 41.9% in impurity. The maximal concentration of dust reached to 446.67mg/m~3, The action of free silica might be the main cause of feather worker pneumoconiosis. The X-ray morphological changes of five pneumoconiosis patients revealed that irregular S-shaped shadows(density I) were shown in middle and lower pulmonary area. Damage of lung function appeared mainly to be obstructive. The clinical menifestations of exposers. chiefly included "feather fever" (61.1%, 113/185), skin allergy and irritability of the upper respiratory tract: IgA and IgG of the exposed workers were shown to be lower than that of the controls.

本文调查了羽毛加工业的粉尘危害,该粉尘为一种混合性粉尘,除羽毛有机成份外还含有大量的杂质。其游离SiO_2含量取决于杂质的多寡,羽毛中平均含量为2.3%,而杂质中高达41.9%。粉尘浓度最高达446.67mg/m~3。认为羽毛工尘肺的致病原因,首先应考虑是SiO_2的作用。5例羽毛工尘肺X线形态为两中、下肺区不规则S形Ⅰ级密集度小阴影,个别有少量类圆形小阴影。肺功能以阻塞性障碍为主。接触者主要表现是“羽毛热”,占61.1%,其次是皮肤过敏及上呼吸道刺激症状。接触者免疫球蛋白(IgA、IgG)明显低于对照组。
