动物实验证实铝尘可致肺纤维化,但也见铝尘无害的报道。为了进一步了解铝尘对作业工人健康的影响,我们对上海铝加工工业中的有关车间作了劳动卫生学调查,并对48名工龄在10年以上的作业工人进行了健康检查。调查内容及方法铝尘车间劳动卫生调查包括生产工艺过程,车间空气中粉尘浓度、分散度、游离二氧化硅及元素成分分析。粉尘浓度测定采用滤膜重量法,由于所得浓度值呈偏态分布,统计处理用几何均数表示。
Animal experiments confirmed that aluminum dust can cause pulmonary fibrosis, but also see the report of harmless aluminum dust. In order to understand more about the impact of aluminum dust on the health of workers, we conducted a survey of labor hygiene in the workshops in the aluminum processing industry in Shanghai and conducted a health check on 48 workers who were over 10 years old. Survey content and methods Aluminum dust workshop labor hygiene survey including the production process, workshop dust concentration in the air, dispersion, free silica and elemental composition analysis. Determination of dust concentration using the membrane weight method, as the resulting concentration values were skewed distribution, statistical processing, said geometric mean.
