本文对大华陶瓷厂142例陶工尘肺进行33年动态观察结果分析如下: 该厂于1949年建厂,设备简陋,通风条件差,车间粉尘浓度高,经采用综合方尘措施,粉尘浓度明显下降,但合格率仍很低超过国家卫生标准10倍左右。该厂历年受检总数为520人,尘肺累积发病142例(男135例,女7例),总患病率为27.31％其中晚发尘肺例,占发病人数的41.55％,平均发病工龄22.60年。1958年首次照片累积发病例数较多。不同时间发病率与工种发病率进行比较无统计学意义。平均发病工龄原料工最短为18年,烧制工最长为27.32年,随着粉尘浓度与生产规模变化,平均发病工龄延长,但晋期年限有缩短趋势。
The paper analyzes the dynamic observation results of 142 cases of potter’s pneumoconiosis during the 33 years in Dahua Ceramics Factory. The plant was built in 1949 with simple equipment, poor ventilation and high workshop dust concentration. , But the pass rate is still very low than the national health standards about 10 times. The factory over the years the total number of subjects was 520 people, pneumoconiosis cumulative incidence of 142 cases (135 males and 7 females), the overall prevalence was 27.31% of which cases of pneumoconiosis, accounting for 41.55% of the number of patients with an average age of 22.60 years . The first photo in 1958 cumulative incidence of more cases. There was no significant difference between the morbidity and occupational incidence at different times. The average length of service for the shortest raw material workers for 18 years, the longest firing of 27.32 years, with the dust concentration and production scale changes, the average length of service extended, but the Jin years have shortened the life expectancy.
