Abstract

Among 1216 workers who were employed in a polyvinyl chloride production factory and who had had no previous dust exposure elsewhere, 20 cases of pneumoconiosis were found. Chest x-ray abnormalities were characterized by limited profusion, irregular type and low gravity. All 20 workers had been exposed to high PVC dust levels. The chest x-ray changes were observed after a minimum exposure of five years and, in a small percentage of cases, were associated with slight restrictive respiratory function impairments. Moreover, in the whole group of workers 388 cases (31.9%) were found with non-specific x-ray abnormalities mainly related to age and smoking.

摘要

在1216名受雇于聚氯乙烯生产工厂且此前未在其他地方接触过粉尘的工人中，发现了20例尘肺病病例。胸部X光异常的特点是病变程度有限、形态不规则且密度较低。所有20名工人都曾暴露于高浓度的聚氯乙烯粉尘中。胸部X光变化在至少接触五年后被观察到，并且在一小部分病例中，与轻微的限制性呼吸功能损害有关。此外，在整个工人群体中，发现388例（31.9%）有非特异性X光异常，主要与年龄和吸烟有关。
