PM2.5 is also called fine particles, fine particles called fine, fine particles. Atmospheric particle size less than 2 mu m (sometimes with less than 2.5 m, PM2.5) particles (aerosols). Although the fine particles just group content of a few earth atmospheric composition in the points, but it has an important influence on air quality and visibility. Fine particle size small, rich in a lot of toxic, harmful substances and residence time in the atmosphere of long, long conveying distance, and thus the impact on human health and the quality of atmospheric environment of the greater. In 2012 February,the State Council agreed to the release of the new revised "ambient air quality standard" increased the fine particulate monitoring index. In February 28, 2013, the national science and TechnologyTerminology Committee called the PM2.5 quasi officially named as the "fine particles".

Although the fine particles just group content of a few earth atmospheric composition in the points,but it has an important influence on air quality and visibility. Compared with the atmospheric particlesof coarse and fine particles with small particle size, rich in a large number of toxic and harmfulsubstances and the atmospheric residence time of long, long conveying distance, and thus the impact on human health and the quality of atmospheric environment of the greater. Research shows that the smaller the particle on human health hazards more. Fine particles can drift to far away places, so the larger sphere of influence. In addition, fine particulate matter on human health hazardis greater, because the more small diameter, the parts of the deeper into the respiratory tract. 10 m diameter particles are usually deposited in the upper respiratory tract of 2 mu m or less can be deep into the bronchioles and alveoli. Fine particles into the human body to the alveoli, directly affect thelung ventilation function, make the body easily in anoxic condition. And this kind of fine particulate matter once it enters the alveoli, adsorption in the alveoli is difficult to drop, the sorption is irreversible.
