This paper mainly deals with the measurement of air quality by observing the concentration of pollutants in the atmosphere namely suspended particulate matter, NOx and SO2 at five different selected locations in Lucknow city. The locations for the study have been chosen on the basis of land use pattern. Each pollutant has been observed by 12 hours from 8:00 to 20:00 hours. According to air quality scale, the air quality status has been measured at each location and zone. From the study it is found that the residential zone has highest air quality index in comparison to other zones.
Pollution control strategies for attainment of particulate standards must be able to provide convincing evidence that the relative importance of emission sources is understood and that the control programmes proposed are cost-effective and can be adopted by the community with confidence.
There are several methods to communicate the use of different environmental quality parameters. This research communication discusses the use of Air Quality Index (AQI) describing air pollution in Choudwar area. AQI is computed for ten air quality sampling stations in the Choudwar area within the radius 10 kms from the core zone.
For the city of Delhi, an air quality index methodology was proposed and applied for six criteria pollutants - PM10, PM2.5, CO, NOx, SO2, and Ozone and analyzed for trends in the past three years of data. The AQI is reported on a scale of 0 to 500 and subdivided into six colored bins for easy understanding of the common person and the media.
