近年来,粉尘作业工人离尘后患矽肺的问题引起了人们的注意,并多称之谓“晚发性矽肺”。但离尘后究竟要观察多少年?其发病与接尘时间、粉尘性质的关系等都有待探讨和认识。 本文分析我区1965～1983年矽肺发病资料,以探讨脱尘工人“晚发矽肺”发生发展规律,为进一步做好矽肺防治工作提供参考。 In recent years, the problem of dust-sucking workers suffering from silicosis has drawn people’s attention and called it “late-onset silicosis.” However, how many years should we observe from the dust? The relationship between the incidence and dust collection time and the nature of dust have yet to be explored and recognized. This article analyzes the data of silicosis from 1965 to 1983 in our district to investigate the occurrence and development of “late silicosis” in dust-removing workers and provide reference for further prevention and treatment of silicosis.
