First of all let us do a little popular science, PM2.5 is just fine particles as the name. Fine particulate matter is the particulate matter in ambient air, which is less than 2.5 microns in diameter. how big is 2.5 micron? For example, an adult's hair is 60~80 microns in diameter, and PM2.5 is a little more than a 1/20 of hair, the scale of the picture is 10 microns, red arrow refers to the black small particles of about equal to 2.5 microns, which has been the largest PM2.5, the larger than this can only say that ordinary dust. It can be seen that the main components of the haze is smaller than pictures in twitter.
