Organic pollution sources, inorganic pollution sources, thermal pollution sources, noise pollution sources, radioactive pollution sources, pathogen pollution sources and mixed pollution sources that emit multiple pollutants at the same time, industrial pollution sources, agricultural pollution sources, transportation pollution sources and domestic pollution sources.
Pollution sources are divided into fixed pollution sources and mobile pollution sources. Stationary pollution sources refer to emission sites such as flues, chimneys, and exhaust cylinders. The exhaust gases emitted by them contain not only solid soot and dust, but also a variety of harmful substances in gaseous and aerosol forms.
Such as coal-fired chimneys of power plants, large industrial chimneys of steel plants, cement plants, aluminum smelting plants, non-ferrous metal smelters, phosphate fertilizer plants, nitric acid plants, sulfuric acid plants, petrochemical plants, chemical fiber plants, etc. Mobile pollution sources mainly refer to exhaust sources such as traffic vehicles, aircraft, and ships, whose exhaust gases contain soot, organic and inorganic gaseous harmful substances.
Primary pollutants: pollutants released from pollution sources that directly endanger human health or cause a decline in environmental quality.
Secondary pollutants: A series of physical, chemical and biochemical reactions produced by emitted substances under certain environmental conditions, resulting in a decline in environmental quality.

Yes. A small button battery can pollute 600 cubic meters of water, which is equivalent to the amount of water a person drinks in a lifetime; A No. 1 battery rotting in the ground can make one square meter of land lose its use value and cause permanent pollution, and its permanence is equal to the power of a nuclear bomb. >>>More
