Objective To explore the spatial and temporal distribution characteristics of major air pollutants in Nanjing, and to propose practical countermeasures for the study of air pollution control measures .Methods The daily concentration sequence records of air quality index and various pollutant sub-indexes in Nanjing from 2013 to 2014 and the daily concentration records of air quality index of two suburban national control points in Xuanwu District and Pukou District of Nanjing were collected. The main changes in atmospheric quality in Nanjing were explored by observing daily, weekly and monthly mean and annual mean changes. Results Through observation and comparison, the overall air quality in 2014 was slightly better than that in 2013 and reached the lowest in the whole year in August, but the air quality index remained high around July-August. According to the analysis, in August, the Youth Olympic Games was held in Nanjing, and a series of air remediation measures were carried out to meet the requirements of the contract. However, these remediation measures also stopped with the end of the Youth Olympic Games. As a result, the air quality index rose sharply after August. Conclusion The results of the study verified the effectiveness of the remediation measures taken in the early stage of the Youth Olympic Games, and this control measures can also be used in the future atmospheric remediation. It should be noted that in the development of relevant prevention and control measures, Consider the impact on the economic activities of related industries.
