摘　　要：近年来由空气细颗粒物(PM2.5)引起的大气污染现象频发,成为全社会广泛关注的环境问题。结合国内外研究,综述了PM2.5污染的来源、危害及控制对策的相关研究进展。研究表明,人类活动排入大气中的一次颗粒物、一次颗粒物与大气中的气态污染物相互作用形成的二次颗粒物是PM2.5的主要来源。长期暴露在PM2.5环境中,会对人体的呼吸系统、心脑血管系统、神经系统及免疫系统的健康造成伤害。PM2.5还会导致大气能见度下降,影响正常的生产、生活。针对中国PM2.5的污染现状,提出了PM2.5污染的控制对策及建议。In recent years, atmospheric pollution caused by air fine particulate matter（PM2.5） happens frequently in most areas of China, which has seriously affected the human body health and industrial production and thus received extensive concern form the whole society. This paper reviews the research progress on the source and harm of air fine particulate matter pollution and control strategies. The primary particulate matter and secondary particulate matters, largely produced by human activity, are the main sources of PM2.5. When people are constantly exposed to air polluted by PM2.5, the human respiratory system, cardiovascular system, nervous system and immune system are jeopardized badly. In addition, PM2.5 could cause a decline in the atmospheric visibility, which will affect the normal production and life. According to the current status of PM2.5 pollution, comprehensive suggestions for China＇s PM2.5 pollution control are put forward.
