As air quality across Indian cities reaches hazardous levels, the need for awareness and action has never been more pressing. Two of India’s largest metropolitan hubs, Mumbai and Delhi, are particularly affected by the high Air Quality Index (AQI) levels that are posing a threat to public health, the environment, and urban living standards. In this blog, we’ll explore the current AQI situation in Mumbai and Delhi, the sources of pollution, the health risks involved, and actionable ways to combat this issue.

What is AQI and Why is it Important?

The Air Quality Index (AQI) is a measurement tool used worldwide to assess the air quality of a particular location. It considers major pollutants like particulate matter (PM2.5 and PM10), nitrogen dioxide, sulfur dioxide, carbon monoxide, and ozone. The AQI is presented on a scale from 0 to 500, with higher values indicating worse air quality. According to AQI standards:

0-50 is considered good.

51-100 is moderate.

101-200 is unhealthy for sensitive groups.

201-300 is unhealthy for the general population.

301-500 is very unhealthy to hazardous.

In recent years, both Mumbai and Delhi have frequently recorded AQI levels over 300, falling into the “very unhealthy” and “hazardous” categories, where the health impact on the population becomes severe.

Current AQI Levels in Mumbai and Delhi

Delhi has consistently ranked among the world’s most polluted cities, with winter months bringing a dramatic increase in pollution levels due to a combination of agricultural burning, vehicle emissions, and weather conditions that trap pollutants close to the ground. This year, Delhi’s AQI has reached levels over 400 in many areas, creating an alarming situation for public health.

Mumbai, although often viewed as a coastal city with a comparatively lower AQI, has seen a rise in pollution levels. This can be attributed to rapid urbanization, construction dust, vehicle emissions, and industrial activities. In the winter months, Mumbai’s AQI has occasionally crossed 300, a level at which the air quality is classified as “very unhealthy.”

Causes of High AQI in Mumbai and Delhi

Both cities face pollution from a mix of sources, but each has unique contributors to their high AQI levels:

1. Vehicle Emissions: Both Mumbai and Delhi have high vehicle densities, contributing significant amounts of carbon monoxide, nitrogen dioxide, and particulate matter. Heavy traffic congestion exacerbates this issue, especially during peak hours.
2. Construction Dust: Rapid construction and infrastructure development release particulate matter into the air, worsening air quality in both cities.
3. Industrial Pollution: Factories and power plants emit sulfur dioxide, nitrogen oxides, and particulate matter. Industrial zones in and around Mumbai and Delhi contribute substantially to poor air quality.
4. Agricultural Burning: In Delhi, stubble burning in neighboring states significantly increases pollution in winter, with smoke drifting into the city and trapping pollutants under colder, stagnant air.
5. Waste Burning: Burning of municipal and industrial waste is a significant problem, particularly in densely populated areas with limited waste management facilities.

Health Implications of High AQI

Poor air quality can lead to serious health issues, particularly for vulnerable groups like children, the elderly, and those with pre-existing respiratory or cardiovascular conditions. Health risks include:

Respiratory Issues: High levels of particulate matter and gases can cause or worsen asthma, bronchitis, and other respiratory diseases.

Cardiovascular Problems: Long-term exposure to polluted air increases the risk of heart attacks, strokes, and high blood pressure.

Eye and Skin Irritation: Exposure to pollutants can cause red, itchy eyes and skin irritation.

Practical Solutions for Better Air Quality

Reducing AQI and improving air quality requires a multi-faceted approach, with actions that both individuals and authorities can take:

1. Implement Effective Waste Management Solutions: Effective waste management and recycling can reduce the need for open-air burning of waste, a significant source of pollution. Clean Geosphere is committed to providing sustainable waste management solutions to help reduce this contributor to pollution.
2. Use Public Transportation: Reducing personal vehicle use and encouraging public transportation, biking, or walking can significantly lower vehicle emissions. For those who drive, switching to electric or hybrid vehicles can also make a difference.
3. Promote Green Spaces: Greenery absorbs pollutants and improves air quality. Both cities need more urban green spaces, which can provide some relief from pollution.
4. Support Government Initiatives: Government programs, like “Odd-Even” vehicle policies, stubble management incentives, and stricter industrial emission regulations, are essential. Supporting these measures can help reduce the AQI significantly.
5. Awareness and Education: Educating the public on air pollution and how their daily actions can either contribute to or help reduce pollution is essential. Schools, workplaces, and communities should make air quality awareness a priority.
