It is that time of the year again when the AQI Delhi is in the 'Severe' category. The capital of India, Delhi, is considered one of the world's most polluted cities by WHO, according to a survey comprising 1,650 cities across the globe. In fact, the survey shows that of all the major global cities, Delhi pollution level is the worst. The poor Delhi AQI, apart from causing massive cases of chronic bronchitis and asthma, is also perpetuating a negative impact on children's health.
Nearly 2.2 million children, which amounts to 50% of the total population of children in Delhi, are showcasing irreversible damage in their lungs due to uncontrolled exposure to the toxic Delhi AQI. Here, we have discussed what AQI is, and the causes and effects of the Delhi pollution.
What is AQI?
AQI stands for the Air Quality Index, which is used to measure the quality of air in a particular region. AQI runs from level 0 to 500, and the higher the AQI, the greater the air pollution level. The recent Delhi AQI has been between 'Unhealthy' to 'Hazardous' levels.
Delhi pollution level was the worst in November 2021, when the AQI was recorded as 377. This year also, the pollution levels have been in the 'Hazardous' category.

Effects of Poor Air Quality in Delhi
The Supreme Court of India, in one of its historical statements on Delhi pollution, said, "Delhi has become worse than narak (hell)." In fact, Justice Arun Mishra went on record saying that it was better to blow up Delhi with explosives and kill everyone rather than live in the claustrophobic conditions of Delhi.
Essentially, the effects of the poor Delhi AQI are massive, and here, we have discussed the effects on children and adults:
Effects of Delhi AQI on Children
The excessive pollution quotient in Delhi may have adverse effects on the immune systems of the children and risk heinous diseases, including diabetes, cancer, epilepsy, and even autoimmune conditions such as multiple sclerosis. Since children's bodies are in a developing stage, they tend to breathe in more air as per their body weight, making them more vulnerable to rising pollution.
Effects of Delhi Pollution on Adults
In adults, too, the effects of air pollution in Delhi are immense. It is causing a plethora of health issues, such as persistent headaches, reduced lung capacity, fatigue, cough, sore throats, lung cancer, and a reduction in overall life expectancy.
How to Make the Delhi Air Quality Better?
In recent years, Delhi has been consistently coming under the radar for being one of the most polluted cities in the world. The Delhi government, along with the centre and the Supreme Court, are implementing various rules to regulate the traffic and stubble burning in nearby areas to curb pollution. Additionally, the further causes of such severe Delhi pollution are being identified to subsequently take the necessary measures.
