Pollution levels have increased at all stations in Delhi. According to the Central Pollution Control Board, the air quality index in different parts of Delhi ranged from 281 to 416 as of 11 am on October 23, 2024. This means the condition ranges from severe to very serious. If you live in Delhi, let’s say you smoke 4 to 6 cigarettes a day. The same goes for not smoking.
The AQI of each station in Delhi is different. One cigarette emits pollutants equivalent to 64.8 AQI. This means that currently a person in Jahangirpuri and Anand Vihar in Delhi is smoking 6 cigarettes. This also costs nothing. AQI, which stands for Air Quality Index, is getting worse every year. No improvement. Once winter begins, the faces are no longer visible. Masks can be seen while walking.

People, scientists, doctors, administrations and governments are increasingly concerned about the sudden rise in AQI in the last week of October. The probability of its increase during Diwali is 100%. Because the cookies will burst. No matter how much the government or administration says no. Or ban the sale of firecrackers.
Six reasons why pollution is increasing in Delhi-NCR…
Prime Minister’s Party…
The amount of particulate matter in Delhi’s air has increased. These are smoke emitted by vehicles, smoke from industry, straw burning and other types of businesses in the atmosphere. The amounts of PM 2.5 and PM 10 increase in October and November.

Burning straw…
Every year, the remaining parts of the previous crop are burned once cold weather sets in in Punjab and Haryana. This is called straw burning. It is believed that this time the cropping season has gone beyond schedule. As a result, stubble burning has increased in these states.
wind direction…
Wind also contributes significantly to Delhi’s air pollution. Wind direction, wind speed and humidity, these three factors poison the lungs of the National Capital Region of Delhi. After monsoon and before winter, the wind blows from Haryana-Punjab towards Delhi. This wind comes from Pakistan. The smoke of straw also comes with the wind. There is moisture in the air. The weather was heavy and smoke was visible everywhere.
Change the temperature…
Due to frequent temperature changes in Delhi during the winter, pollution also increases. This is called a temperature inversion. Therefore, a layer of hot air forms above the cold air. Therefore, all contaminating elements remain only on the surface. Temperature changes, pollution from vehicles, industry, straw burning… anything can happen.

Motor vehicle pollution…
Delhi has a very large population. In addition, the number of vehicles is also very large. 25% of Delhi’s PM2.5 emissions come from vehicle pollution. Gases and chemicals emitted by industries in and around Delhi also contribute to changes in the atmosphere. Pollution increases.
Other sources of pollution…
Use dry air from a dry area to polish the particles. Chemicals and emissions from burning firecrackers and burning household biomass during Diwali also add to winter pollution. According to a study by IIT Kanpur, 17-26% of particulate emissions in the National Capital Region of Delhi are caused by biomass burning.

What is air quality index?
The Air Quality Index (AQI) is used to report daily air quality. It tells you how clean or polluted the air is and the related health effects you may be concerned about. The AQI focuses on the effects on your health of breathing polluted air for hours or days.
The purpose of the AQI is to help people understand how the air quality around them affects their health. The U.S. Environmental Protection Agency (EPA) calculates the Air Quality Index for five major air pollutants and sets national air quality standards to protect public health.
How is air pollution measured?
AQI is a measure of air purity that indicates how clean the air is in an area. It has different categories that give you an idea of ​​how much pollution is in the air in that place. AQI mainly consists of 8 pollutants (PM10, PM2.5, NO2, SO2, CO, O3, NH3, Pb). PM2.5 and PM10 measure dissolved toxic particles and soil particles.
