Analysis of Air Pollution Trends in Beijing, China
Authors(1) :-Anbu Clemensis Johnson Air pollution is a worldwide problem affecting not only the source location, but the globe as a whole. The current study aims to analyse the standard six air pollutants and air quality index (AQI) in Beijing, China. Air quality data was collected from 2014 to 2020 for temporal analysis. The average maximum values of the air pollutants and AQI during the period analysed were, PM2.5: 74.4 µg/m3, PM10: 107.3 µg/m3, SO2: 20.7 µg/m3, CO: 1.5 mg/m3, NO2: 56.3 µg/m3, O3: 173.1 µg/m3 and AQI: 118. Maximum and minimum values of the primary pollutants occurred predominantly during winter and summer months, while O3 exhibited an opposite trend. All air pollutants and AQI declined over the years. Significant reduction of over 50 % was archived for PM2.5, PM10, SO2, CO and less than 5 % for O3. The air pollution trend in Beijing has shown substantial improvement. In 2020, all air pollutants except PM2.5 achieved the national ambient air quality standard. This realisation can be credited to the effective policies implemented by the Chinese government.
