摘要
PM_(2.5),即大气细颗粒物,是指大气环境中直径小于或等于2.5μm的颗粒物,也称为可入肺颗粒物,是空气污染最主要的因素之一,对环境和人类健康都具有极大的危害。因此,大气环境中的PM_(2.5)污染已成为我国社会公众关注的焦点问题。为了有效解决环境空气污染,提高大气环境质量,减轻污染对人体造成的伤害,落实PM_(2.5)的防治措施刻不容缓。基于此,本文对大气环境中PM_(2.5)的来源、危害、防治意义及措施进行具体研究。
PM_(2.5),also known as fi ne particulate matter in the atmosphere,refers to particles with a diameter less than or equal to 2.5 micrometers in the atmosphere,also known as pulmonary particulate matter.It is one of the main factors of air pollution and poses great harm to the environment and human health.Therefore,PM_(2.5)pollution in the atmospheric environment has become a focal issue of public concern in China.It is urgent to implement PM_(2.5)prevention and control measures in order to eff ectively solve air pollution,improve air quality,and reduce the harm of pollution to human health.Based on this,this article conducts specifi c research on the sources,hazards,prevention and control signifi cance,and measures of PM_(2.5)in the atmospheric environment.
