Delhi’s Air Quality Index (AQI) is a measure of the air quality in the city, and it works by tracking the levels of pollutants in the air. The AQI is calculated based on the levels of five major pollutants: particulate matter (PM2.5 and PM10), nitrogen dioxide (NO2), ozone (O3), sulfur dioxide (SO2), and carbon monoxide (CO).
The AQI is categorized into six levels: good, satisfactory, moderately polluted, poorly polluted, very poorly polluted, and severely polluted. The levels are determined by the average concentration of pollutants in the air over a 24-hour period. When the AQI is high, it means that the air quality is poor, and people may experience health problems.
According to the evidence, Delhi’s 45-degree heat and poor AQI are connected, but the exact mechanism is not explained in the provided source. However, it is mentioned that summer pollution works in a way that is connected to the heat, but the specific details are not provided.
The AQI is an important indicator of air quality, and it helps people understand the level of pollution in the air. It is used by the government and other organizations to take measures to improve air quality and reduce pollution.
