Problems solved by technology

[0003] In order to improve this environmental situation, human beings are required to strengthen environmental protection while pursuing economic development. At present, there is no simple and effective method to obtain the changes and influencing factors of PM2.5 concentration, so as to reduce PM2 from the source. 5 concentration, therefore, it is necessary to explore the changes and influencing factors of PM2.5 concentration value to protect the environment

Abstract

The invention provides a method for analyzing a PM2.5 concentration value and influence factors. The method is characterized by acquiring monitoring data of atmospheric pollutants PM2.5 in a certain city, and studying the data to obtain PM2.5 mass concentration pollution characteristics, change rules, and natural factors and human factors of PM2.5; and aiming at various influence factors of the PM2.5, finding out a correlation relationship and a general rule between PM2.5 and the various influence factors. Through analyzing the influence factors of PM2.5, the source and formation process of particulate matters can be qualitatively identified; meanwhile, the contribution degrees of various pollution sources are qualitatively determined by adopting a regression analysis technology; therefore, the PM2.5 pollution is controlled and weakened, scientific basis and technical support are provided for preventing and controlling large-scale haze outbreak, and reference is provided for further research on influences of PM2.5 on human health, visibility and weather.

Description

technical field [0001] The invention relates to an analysis method of PM2.5 concentration value and influencing factors. Background technique [0002] As the smog problem continues to trouble people, the air pollutant PM2.5 has attracted widespread public attention. PM2.5 is mainly composed of water-soluble ions, particulate organic matter and trace elements. In recent years, a large number of studies have found that PM2.5 has a relatively small particle size and relative PM 10 The specific surface area is larger, so it is easier to enrich organic pollutants, acidic oxides, toxic heavy metals, bacteria and viruses in the air. Its main sources are natural sources and man-made sources, which can be divided into primary particulate matter (that is, the particulate matter that is directly emitted into the atmosphere from the emission source) and secondary particulate matter (that is, the particulate matter that is generated through chemical reactions with atmospheric component...
