对于我国环境空气颗粒物术语定名的建议

文章深入归纳了我国环境空气质量标准中颗粒物术语的演绎过程及主要国家、地区和组织颗粒物术语,提出了适用于我国的颗粒物术语建议:粒径小于等于10微米和粒径小于等于2.5微米颗粒物分别命名为颗粒物(粒径小于等于10微米)和颗粒物(粒径小于等于2.5微米),又分别称为可吸入颗粒物和细颗粒物,英文名称分别为particulate matter(PM₁₀)和particulate matter(PM_2.5)。

Proposal on the Terminology of Ambient Air Particulate Matter in China

The particulate matter is the primary ambient air pollutants in China now and even in the future, while its term has not been unified. We summarized deductive process of the particulate matter terms in Chinese national ambient air quality standards and the particulate matter terminology in major countries, regions and organizations. Furthermore, we proposed the terminology of ambient air particulate matter applied to China. particulate matter with size less than or equal to 10 microns and a particle size less than or equal to 2.5 microns particulate matter were named as particulate matter （particle size less than or equal to lOμm） and particulate matter （particle size less than or equal to 2.5μm） respectively; and were referred as inhalable particle and fine particle, the English names for particulate matter （PMlo） and particulate matter （ PM2.5 ）.
