Delhi’s overall air quality remains ‘severe’, AQI over 450 in some areas

Delhi’s air quality has once again plunged into the ‘severe’ category, with the Air Quality Index (AQI) soaring above 450 in several areas, leaving residents to cope with hazardous levels of pollution. This marks a troubling continuation of Delhi’s long-standing struggle with air quality, particularly during the winter months. The toxic haze, largely attributed to a combination of stubble burning in neighboring states, vehicular emissions, industrial pollution, and unfavorable weather conditions, poses serious health risks to millions of people in the city. On December 20, 2024, air quality monitoring stations across the city recorded alarming AQI figures, some of which exceeded 450. This is well above the threshold for ‘severe’ air quality, which can lead to adverse health effects even for healthy individuals. For those with pre-existing respiratory conditions, children, and the elderly, exposure to such air quality can result in severe complications, including asthma, heart disease, and other chronic ailments. The ongoing pollution levels have overwhelmed the healthcare system, which is already dealing with seasonal respiratory illnesses, making it difficult for hospitals to handle the surge of patients. A significant factor contributing to the current situation is the seasonal practice of stubble burning in Punjab, Haryana, and Uttar Pradesh. Despite government efforts to curb this practice, it remains one of the primary sources of the dense, smoky haze that envelops Delhi each year. Additionally, the combination of low temperatures and stagnant air further traps pollutants, preventing them from dispersing into the atmosphere. This creates a layer of smog that lingers over the city, exacerbating the already dangerous levels of pollution.Vehicular emissions and industrial activity are also major contributors to the city’s air quality problems. With a population exceeding 20 million, Delhi is home to millions of vehicles that pump out harmful pollutants, including nitrogen oxides and particulate matter. Despite initiatives to reduce emissions, the growth in population and vehicles continues to outpace efforts to improve the air quality. The rapid urbanization of Delhi has also led to the proliferation of construction activities, which generate dust and particulate matter that further pollute the air.

In response to the severe air quality, Delhi’s government has implemented a range of measures, including the closure of schools, a ban on construction activities, and restrictions on industrial activities that contribute to pollution. However, these measures are often temporary and lack the long-term solutions needed to address the root causes of air pollution. The government has also been promoting the use of public transport and electric vehicles, but the challenge remains that these steps have yet to make a significant dent in the city’s overall pollution levels.The air quality crisis in Delhi is not just a public health issue, but a social and economic one. The constant exposure to poor air quality is contributing to an increase in medical costs, lost productivity, and a general decline in quality of life for millions of residents. The impact is felt particularly by the urban poor, who live in areas that are more exposed to pollutants but have limited access to healthcare and resources to mitigate the effects of pollution.Experts and environmentalists have long called for more effective action to tackle Delhi’s pollution problem, stressing the need for stringent laws and better enforcement. They argue that the government must take more aggressive steps to reduce vehicular emissions, control industrial pollution, and implement more sustainable urban planning practices. Additionally, investments in green spaces, clean energy, and renewable resources are necessary to reduce the city’s dependency on fossil fuels, which are a major source of pollution. As the air quality in Delhi remains ‘severe’, the situation calls for urgent and sustained intervention at all levels of government and society. Without a concerted effort to address both the short-term and long-term causes of pollution, the city will continue to face health and environmental crises that threaten the well-being of its residents. The time for action is now, before the problem becomes even more difficult to manage.
