PM2.5是大气中直径≤2.5μm的可吸入人体的颗粒物,它不仅影响空气质量和能见度,而且也会对人体健康带来很大的危害。在分析空气中PM2.5来源及其与生产建设项目关系的基础上,提出通过生产建设项目水土保持方案的全面落实来控制项目建设过程中扬尘的产生,从而达到降低空气中PM2.5浓度的目的。
PM2.5 is the particulate matter of breathable human body with the diameter of ≤2.5μm in the atmosphere, which not only affects the air quality and visibility, but also brings great harm to human health. Based on the analysis of the sources of PM2.5 in the air and its relationship with production and construction projects, it is proposed to control the generation of dust in the project through the full implementation of the soil and water conservation program of production and construction projects so as to reduce the concentration of PM2.5 in the air purpose.
