Abstract The essence of air pollution is the impact of air pollutants on human health and environment. The article divides air pollution and control into physical process, chemical processes, and biological, as well as how to describe the three progresses by mathematical methods and to calculate them by computer and reviews systematically their development and interrelationships. This paper summarized the theories, techniques and methods of history, present and existing problems on atmospheric physics, atmospheric chemistry, emission inventory, atmospheric environment monitoring, meteorological field forecast, air quality forecast, source apportionment and tracing source, the impact of air pollution on human health, and atmospheric pollution control. Put forward the theoretical framework, as well as core scientific problems of air pollution hazard identification and control, and pointed out that the theories, techniques, methods and standards of inversion and generation of emission sources, particle toxicity identification, chemical process assimilation, health risk prediction and early warning, synchronization source apportionment of predicting results, and dynamic optimal control are not yet mature, which are the main directions for future development, due to the extremely complicated and staggered influence as well as constraints on physical process, chemical process, biological process as well as mathematical description and computer calculation principle of air pollution and prevention. If the toxicity of pollutants is directly related to health risks, which may provide more direct and effective scientific and technological support for air pollution emergency optimal control as well as the optimal issues of industrial structure adjustment, energy structure adjustment and heavy pollution sources layout, it will play a fundamental role to meet the objective needs of identifying accurately pollution sources, achieving targeted management and promoting ecological civilization construction.
