Air pollution in Delhi has reached a concerning level of 400, which has the potential to significantly affect the overall quality of life for residents.

Tracking Pollution Levels and Air Quality 

Delhi's air quality is counted as the most hazardous and most polluted, which can cause severe health issues. The detrimental air pollution in Delhi contributes to the development of chronic heart conditions that necessitate treatment by cardiologists. Over the past week, there has been an increase in the current Air Quality Index (AQI), reaching 400, while the temperature range has risen from 22 °C to 26 °C. Consequently, the overall air quality and pollution levels in Delhi are severe, posing a significant threat to the health of its citizens.

What Are the Current Air Pollution Levels in Delhi? 

Delhi's pollution level is moving rapidly towards the worst. The current Delhi pollution level crossed from 300 to 400 AQI in just one week. Delhi has been facing severe air pollution for several years, with factors such as vehicle emissions, industrial pollution, and crop burning contributing to the problem.

The government has taken various measures to combat air pollution in Delhi, including implementing the odd-even rule for vehicles, banning the use of firecrackers, and promoting the use of public transportation. However, individuals need to take personal measures as well, such as using air purifiers, wearing masks, and reducing their carbon footprint. Regular monitoring of air pollution levels in Delhi is crucial to stay informed and take necessary precautions to protect our health.

Understanding Delhi Air's Quality 

Delhi's air pollution is increasingly going towards a hazardous situation. The city continuously faces a high rise in air pollution, where air quality is going downwards.

During a conference, the Environment Minister of Delhi emphasized the criticality of the upcoming 15 to 20 days for the city, as it continues to witness an alarming surge in air pollution. The air quality index (AQI) for Delhi has deteriorated significantly, reaching an alarming range of 300 to 400, signifying the poorest air quality. This unfortunate milestone was surpassed by Delhi in the initial week of November 2023.

What Are the Causes of Air Pollution in Delhi?

The air pollution level in Delhi is primarily attributed to various sources of pollution such as garbage waste, road dust, power plant factory waste, and transport gases. This has resulted in the PM 2.5 levels reaching above 400 in November 2023, significantly impacting the Air Quality Index.

Furthermore, the negligence and inconspicuous utilization of transportation and machinery have further contributed to the escalation of air pollution levels in Delhi. The consequences of Delhi's pollution level are causing significant environmental harm and posing health risks to the local citizens, leading to a gradual reduction in their life expectancy daily.

Reasons for Air Pollution in Delhi 

Delhi's air pollution stems from various sources, specifically six major categories including industries, waste disposal, transport dust, domestic cooking, waste burning, and diesel generator sets. Among these, waste burning and transport are the primary contributors to the city's air pollution. Recent news and reports from 2021 highlight the staggering number of registered vehicles in Delhi, totalling 1.50 crores. This influx of vehicles necessitates proper maintenance and regular Pollution Under Control (PUC) checks for individuals.

Consequently, Delhi's pollution level has reached alarming heights, largely due to the impact of transport and vehicles. Furthermore, the persistent practice of stubble burning in neighbouring states such as Punjab, Haryana, and Chandigarh exacerbates Delhi's air pollution problem. The air quality index of Delhi in 2023 has witnessed a significant increase as a result of this ongoing issue.

Impact of Air Pollution on Delhi Residents 

In October 2023, the Delhi Government announced a health emergency in various areas of Delhi, leading to the closure of educational institutions. The dense air smog has posed challenges for aircraft landings at Delhi Airports. Additionally, the Delhi government has implemented a mandatory requirement for all citizens to wear masks or use cloth face coverings while outdoors keeping Delhi's pollution level in mind.

It is highly advised by both local citizens and residents of Delhi to remain indoors as a result of the alarming air pollution levels in Delhi. In response, numerous individuals are opting to relocate outside of Delhi in search of cleaner and more breathable air. The majority of areas in Delhi have now surpassed the threshold of hazardous air quality, posing a significant and urgent concern for both the city and the Indian government.

Air Pollution in Delhi NCR 

The Delhi government in the National Capital Region (NCR) has officially announced the implementation of Grap - 3 measures. These measures encompass the temporary suspension of vehicular movement and the closure of educational institutions throughout all areas of Delhi NCR.

Furthermore, various construction and industrial projects have also been temporarily closed in Delhi NCR. This decision has been made in response to the persistent rise in Delhi's pollution level.


To effectively address the air pollution crisis, it is imperative to tackle the root causes. This entails implementing measures to decrease stubble burning and enforcing stringent regulations to enhance greenery. Additionally, reducing vehicular emissions and managing waste transportation are vital steps towards restoring and maintaining the air quality of Delhi. Moreover, it is essential to establish comprehensive guidelines mandating every citizen's adherence to eco-friendly practices. These rules will play a crucial role in controlling the air pollution level in Delhi and safeguarding the health and well-being of all residents.
