报道:铝电解作业工人所接触的生产性粉尘为氧化铝,还有少数冰晶石、氟化铝等。工人作业环境的沉降粉尘中游离二氧化矽含量为0.5%。历年来粉尘浓度动摇在0.3—512.0mg/m~3之间(平均23.9mg/m~3)粉尘粒径小于5μ者占86%。1961年通过铝尘肺调查,发现一例Ⅰ期氧化铝尘肺(男性,49岁,接尘工龄为11年)。X线胸片所见:两肺中、下野有较
Reported: Aluminum Electrolysis workers contacted by the production of dust for the alumina, there are a few cryolite, aluminum fluoride and so on. Workers in the working environment of the settlement of free silicon dioxide content of 0.5%. Over the years the concentration of dust fluctuated between 0.3-512.0mg / m ~ 3 (average 23.9mg / m ~ 3) dust particle size less than 5μ accounted for 86%. A survey of aluminum pneumoconiosis in 1961 found that a case of stage I pneumoconiosis (male, 49 years old, dusting age was 11 years). X-ray findings: two lungs, under the field more
