The author of this book in the field of PM2.5 based on more than 10 years, according to the research progress at home and abroad from the basic concept of PM2.5, the research significance and historical perspective, combing the chemical group PM2.5 sample collection, analysis and remote sensing inversion method, summarized characteristics and origin of the different city of PM2.5, introduces the principle and technique of source apportionment application of emission spectrum and source emission inventory, discusses the mechanism of heavy haze pollution events, through the case analysis of PM2.5 on visibility, cultural relics corrosion, ecological system, the formation of acid rain and other environmental impacts, as well as its health and climate effects, out of the United States and Europe PM2.5 management and control experience, proposes a framework of PM2.5 Management Countermeasures in China, and summarizes the main sources of pollution control technology PM2.5.
Since the end of 2011, several large-scale haze events aroused concern about PM2.5. State Council in February 2012 promulgated the new air quality standards, make China become the first introduction of PM2.5 standards in developing countries. On 2016 the formal implementation of new PM2.5 standards, each city will face the urgent task of PM2.5 control. At present, China is still lack for PM2.5 research and pollution control of specialized textbooks or monographs, which in a large extent limits people in-depth understanding of the behavioral characteristics of PM2.5 and pollution control work. In order to meet the urgent requirement of our country current PM2.5 pollution research and control, are in urgent need of combing the PM2.5 research achievements around the urgent need to carry out pollution control work summary of the theoretical system of PM2.5.
The publication of the book, from the concept of PM2.5 and sampling analysis, remote sensing observation, physical and chemical composition and spatial distribution, sources, climate effects of environmental health, management and control etc. aspects to establish a relatively complete PM2.5 scientific system, the focus of research PM2.5 more involved, at this stage of PM2.5 and control of the key content of the induction and the summary, and put forward the direction of future work, in order to meet the need of all kinds of scientific and technical and management personnel, for the national urgent governance PM2.5 and haze pollution as a modest.
