PM2.5 refers to particles with a diameter less than or equal to 2.5 microns in the atmosphere, also known as particles that can enter the lungs. PM2.5 has a small particle size, is rich in a large number of toxic and harmful substances, stays in the atmosphere for a long time and has a long transportation distance, so it has a great impact on human health and atmospheric environmental quality.

The main pollution source of PM2.5 is automobile pollution, especially in winter and early spring. The self-purification function of plants in the north is almost zero, many water surfaces are frozen, and the self-purification ability of water areas is also very low, which needs to be treated manually.
