本文应用改进机率窗分析法,分析广东省18个工业系统主要尘肺在全省全面开展综合防尘前后的尘肺病发生情况。结果显示。全面开展综合防尘后煤炭、有色金属等11个工业系统,特别是尘肺病较多的有色金属等4个工业系统,主要尘肺的发生明显少于全面开展综合防尘前,说明全省多数工业系统防尘效果好,对尘肺病的发生起了明显的预防,控制作用。 In this paper, the improved probability window analysis method was used to analyze the occurrence of pneumoconiosis before and after comprehensive dust prevention in 18 provinces in Guangdong Province. The results show. After comprehensively carrying out dust prevention, 11 industrial systems such as coal and non-ferrous metals, especially 4 non-ferrous metals with more pneumoconiosis, the occurrence of major pneumoconiosis was significantly less than that before the comprehensive dust-prevention was carried out. This shows that most industries in the province System dust effect is good, the occurrence of pneumoconiosis has played a significant preventive and control effect.
