摘　　要：空气中存在的超细颗粒物会对人们的身体健康造成极大危害。近年来,人们对PM2.5等大颗粒物进行了大量的研究,确认了大颗粒物对人体健康造成危害的因果关系。但是,空气中的超细颗粒物粒径比PM2.5颗粒物更小,数量更多,其特点与对人体健康的影响仍不清楚,由于缺少统一的检测方法,在一定程度上影响了健康评估。本文将对国内外的检测方法、仪器及策略进行分析,探讨超细颗粒物浓度检测的影响因素。Ultrafine particulate matter in the air can cause great harm to people's health. In recent years,a large number of studies have been carried out on PM2.5 and other particulate matter,confirming the causal relationship between large particulate matter and human health hazards. However,the particle size of ultrafine particles in air is smaller than PM2.5 particles but there are more of them. Its characteristics and impact on human health are still unclear. The lack of a unified detection method has affected health assessment to a certain extent. In this paper,the detection methods,instruments and strategies at home and abroad will be analyzed,and the influencing factors of ultra-fine particulate matter concentration detection will be discussed.
