为查清本地区陶工尘肺的发病规律,探讨防治对策,近年来我们在原有资料上对本地区陶工尘肺进行一次流行病学调查,结果如下。卫生学调查:于1976～1986年间调查国营、集体厂家各3个,各厂职工50～200多人;厂龄短者五十年,长者百余年;原来生产设备及工艺流程落后,1976年后已逐步实现机械化或半机械化生产,各工序以湿式作业为主,自然通风。经用滤膜法测定作业场所空气中的粉尘浓度(mg/m~3):陶尘0.83～146,均值
In order to find out the regularity of the incidence of potter’s pneumoconiosis in this area and to explore the countermeasures for prevention and treatment, we conducted an epidemiological investigation of the potter’s pneumoconiosis in our region in the previous years. The results are as follows. Hygiene survey: Between 1976 and 1986, three state-owned enterprises and collective manufacturers were surveyed, each with more than 50 to 200 employees. The plant factory was short of 50 years and the elderly was more than 100 years old. The original production equipment and process were backward, 1976 After the year has been gradually mechanized or semi-mechanized production, the process of wet-based operation, natural ventilation. The dust concentration (mg / m ~ 3) in the air of the working place was measured by the filter method: 0.83 ~ 146 of dust, mean
