The atmospheric pollutants enter the atmosphere (input) from an artificial source or a natural source, participate in the circulation process of the atmosphere, and are removed from the atmosphere (output) through chemical reaction, biological activity and physical sedimentation in the atmosphere after a certain residence time. If the output rate is less than the input rate, it will accumulate relatively in the atmosphere, causing an increase in the concentration of a substance in the atmosphere. When the concentration is raised to a certain degree, acute and chronic harm is caused to people, organisms or materials directly or indirectly, and the atmosphere is polluted.
Atmospheric pollutants are those substances that are emitted into the atmosphere due to human activities or natural processes and have a harmful effect on the environment or humans. Atmospheric pollutants can be divided into two main categories according to their existence: one is aerosol state pollutant, and the other is gas state pollutant; if classified according to the formation process, the pollutants can be classified into primary pollutants and secondary pollutants.
