摘　　要：本文报道了石墨尘肺的调查结果。不同工种的粉尘浓度为10.21～87.97mg/m^3,分散度<5μm者占80～90%。五种鳞片石墨产品中游离SiO_2含量为0～3%。对384名接触鳞片石墨粉尘工人进行了体检,石墨尘肺患病率为7.29%,发病工龄平均为20.30年,由Ⅰ期进展到Ⅱ期平均为7.95年,石墨尘肺患者肺功能受到了不同程度的损伤,X线胸片表现以类圆形小阴影“p”改变为主。A survey on graphite pneumoconiosis was reported. The results showed that the dust concentration in different worksites were varied from 10.21mg/m^3 to 87.97mg/m^3; the dust dispersity less than 5μm was in the proportion of 80～90%. The free SiO_2 contents of five kinds of seale graphite products were shown to be 0～3%, 384 workers who exposed to those dust were examined physically. The incidence of graphite pneumoconiosis was 7.29%; the average working age for developing pneumoconiosis was 20.30 years; the averaged deeloping period from Ⅰ to Ⅱ stage appeared to be 5.62 years. The pulmonary function of graphite pneumoconiosis were damaged in different extent. The change on X-ray showed round-like little shadow 'p' predominantly.
