Delhi experienced its worst Delhi air pollution on Diwali in four years; PM2.5 concentrations peaked at 675 micrograms per cubic meter, a level not seen since 2021. This severe air quality significantly impacts public health. The city’s 24-hour average Air Quality Index (AQI) was in the ‘very poor’ category at 345 on Monday, according to the Central Pollution Control Board (CPCB).

Understanding Delhi’s Air Quality Metrics

The CPCB defines AQI values for clarity: ‘good’ (0-50), ‘satisfactory’ (51-100), ‘moderate’ (101-200), ‘poor’ (201-300), ‘very poor’ (301-400), and ‘severe’ (401-500). Diwali celebrations notably worsened air quality this year. For instance, PM2.5 levels surged from 91 micrograms per cubic meter at 4 pm to a peak of 675 by midnight. Conversely, these levels dropped to 91 micrograms per cubic meter by late Tuesday. Such sharp fluctuations underscore the immediate impact of festival activities on air quality. Environment Minister Manjinder Singh Sirsa claimed all data remained intact, despite some expert concerns about missing peak hour readings. Hourly bulletins consistently confirmed persistently high AQI readings throughout the night and into early morning.

Health Impacts of Delhi Air Pollution

Elevated Delhi air pollution profoundly impacts public health, especially for vulnerable populations. Fine particulate matter (PM2.5) easily penetrates the respiratory system. This causes significant harm, particularly to children, the elderly, and those with pre-existing respiratory conditions. Research indicates that prolonged exposure to high pollution levels can irreversibly damage children’s lungs. Additionally, air pollution correlates with increased risks of chronic respiratory diseases, asthma, and certain cancers. Across India, studies report that air pollution contributes to millions of premature deaths annually. Moreover, exposure can trigger low-grade inflammation throughout the body. This consequently elevates the risk of heart attacks, strokes, and other serious cardiovascular diseases. Addressing these widespread health impacts therefore remains a critical public health challenge.

Factors Contributing to Diwali Pollution

Several factors contributed to the severe air quality during Diwali. Transport emissions accounted for 14.6 percent of the city’s air pollution on Tuesday. Additionally, contributions came from neighboring states: Ghaziabad at 6 percent, Noida at 8.3 percent, and Gurugram at 3.6 percent. Stubble burning, particularly in Punjab, Haryana, and Uttar Pradesh, added 1 percent to the total. Satellite data confirmed 45 stubble-burning incidents in Punjab, 13 in Haryana, and 77 in Uttar Pradesh on Diwali. The Supreme Court had permitted green firecracker bursting between 8 pm and 10 pm. However, reports indicated that celebrations often continued beyond this allotted time. Dipankar Saha, former head of Air Laboratories at CPCB, explained that low or calm wind speeds, frequently resulting from depressions in the Bay of Bengal, impede pollutant dispersion. Consequently, pollutants accumulate, leading to a sudden rise in AQI. Earlier, the Commission for Air Quality Management (CAQM) invoked Stage II of the Graded Response Action Plan (GRAP) across Delhi-NCR, demonstrating proactive regulatory measures.

Frequently Asked Questions

Q1: What are the primary health risks associated with high PM2.5 levels in Delhi?

High PM2.5 levels in Delhi can lead to severe health issues. These include irreversible lung damage in children, aggravated asthma, chronic obstructive pulmonary disease (COPD), and an increased risk of heart attacks, strokes, and certain cancers. These fine particles easily enter the respiratory system and bloodstream, causing widespread systemic inflammation. For healthcare professionals dealing with such systemic impacts, understanding comprehensive care is crucial. Consider exploring the International Post Graduate Program In Cardiology to deepen knowledge in cardiovascular disease management.

Q2: How does Diwali contribute to the increase in air pollution in Delhi?

Diwali celebrations significantly increase Delhi’s air pollution primarily through the widespread bursting of firecrackers. Despite judicial restrictions, reports suggest continued use beyond permitted hours. This, combined with factors like stubble burning in neighboring states and adverse meteorological conditions such as low wind speeds, leads to a sharp increase in particulate matter concentrations.

Q3: What measures are authorities implementing to combat Delhi’s air pollution?

Authorities are implementing various measures to combat Delhi’s air pollution. These include the Graded Response Action Plan (GRAP), which imposes escalating restrictions based on air quality levels. The Supreme Court issues directives, such as regulating firecracker sales and timings. Moreover, pollution-tracking models like the Decision Support System (DSS) help identify source contributions to inform policy interventions. The complexities of public health challenges like air pollution underscore the need for continuous learning. The Pulmonology Speciality Courses offered by OC Academy can provide specialized knowledge in this critical area.
