Question

interpretation of data of air quality index in different cities of India​

Answer 1

Answer:

An air quality index (AQI) is proposed for the City of Kanpur, India, for simplified public information and data interpretation. A maximum operator concept is used to determine the overall AQI; maximum value of sub-indices (of each pollutant) is taken as the overall AQI. The mathematical functions for calculating sub-indices are proposed based on health criteria of the USEPA and Indian air quality standards. The pollutants included in the AQI are: SO2, SPM (suspended particulate matter), O3, NO2, PM10 (particulate matter with a diameter of 10 μm or less), and CO. The investigations into data interpretation using the AQI for Kanpur city have shown that air quality worsens (very poor to severe) in winter months and also during the early summer months (March, April, and part of May). These months are characterized by dusty winds resulting in high SPM. The air quality generally improves in monsoon and post-monsoon period (good to moderate) as rain washes out the pollutants. Over 95% of the time, sub-index values corresponding to SPM levels were responsible for overall AQI. Key words: air quality index, air quality data interpretation, Kanpur, India.

Answer 2

The AQI or Air quality index in different cities of India​ is interpreted below:

Explanation:

• The Air Quality Measure (AQI) is a daily air quality index. It shows you how clean or polluted your air is, as well as what health hazards are associated with it. The AQI measures the health impacts you could have a few hours or days after inhaling polluted air.
• If we had to interpret the data of air quality index in different cities of India we need to take certain cities as examples - Kolkata, Delhi, Mumbai, and Chennai.
• For Kolkata the quality of air is considered Hazardous but acceptable; however, for some pollutants there may be a moderate health concern.
• Mumbai is also considered Hazardous and has the highest concentration of pollutants such as PM10 among the 24 major cities of peninsular India.
• Delhi Air Quality Index (AQI) is currently Unhealthy but rises to Hazardous levels, which can be seen to be the same in Chennai.
