The Impact of Air Pollution on Lung Health: A Northeast India Perspective

Introduction
Air pollution is an ever-growing concern globally, and its effects on lung health are alarming. For residents of Northeast India, including cities like Guwahati, Shillong, and Imphal, the problem is becoming increasingly prominent. The region, known for its lush greenery and fresh air, is now grappling with rising air pollution due to urbanization, industrialization, and vehicular emissions. In this blog, we will explore how air pollution impacts lung health, why this issue is significant for the Northeast, and what can be done to protect our lungs.

Understanding Air Pollution and Its Sources in Northeast India

Air pollution in Northeast India stems from several sources:

1.    Vehicular Emissions: Rapid urbanization in cities like Guwahati has led to increased traffic, contributing significantly to air pollution.

2.    Construction Dust: The surge in construction projects releases fine particulate matter (PM2.5 and PM10) into the air, which can severely harm lung health.

3.    Industrial Emissions: While the Northeast is less industrialized compared to other regions, industries like oil refineries and cement factories contribute to air pollution.

4.    Biomass Burning: Many rural households still rely on wood and biomass for cooking, which releases harmful pollutants into the atmosphere.

5.    Stubble Burning: Agricultural practices in Assam and surrounding states sometimes involve stubble burning, further worsening air quality.

How Air Pollution Affects Lung Health

1. Chronic Respiratory Diseases
Air pollution is a major risk factor for asthma, chronic obstructive pulmonary disease (COPD), and bronchitis. Fine particles like PM2.5 can penetrate deep into the lungs, causing inflammation and long-term damage.

2. Reduced Lung Function
Prolonged exposure to polluted air can lead to a decline in lung capacity, especially in children and the elderly. Poor lung function makes individuals more susceptible to infections like pneumonia and tuberculosis.

3. Worsening of Pre-existing Conditions
For people already suffering from respiratory issues, air pollution acts as a trigger, causing frequent flare-ups. For instance, many asthma patients in Guwahati report worsened symptoms during winter when pollution levels peak.

4. Lung Cancer
Long-term exposure to toxic air pollutants like benzene, a common byproduct of vehicular emissions, significantly increases the risk of lung cancer.

5. Impact on Children and the Elderly
Children are particularly vulnerable as their lungs are still developing. Similarly, the elderly, who often have compromised immunity, are more likely to experience severe respiratory issues.

Air Pollution in Guwahati: A Closer Look

Guwahati, the gateway to the Northeast, has witnessed a sharp rise in air pollution in recent years. The Air Quality Index (AQI) during winter often crosses the safe limit, affecting residents’ lung health. Key contributors include:

  • Congestion on major roads like GS Road and RG Baruah Road.
  • Dust from construction in areas like Beltola and Kahilipara.
  • Industrial activities in nearby zones like Amingaon.

The Northeast Advantage: Room for Improvement

Despite these challenges, Northeast India still has an edge over other regions of the country. Its dense forest cover, hilly terrain, and lower industrialization provide a natural buffer against air pollution. However, unchecked urbanization and deforestation could erase these advantages.

Protecting Your Lungs from Air Pollution

1. Use Masks
Wear an N95 mask or a similar respirator when AQI levels are high, especially in crowded areas like markets and busy roads.

2. Monitor Air Quality
Regularly check the AQI in your city using apps or websites. Avoid outdoor activities when pollution levels are high.

3. Purify Indoor Air
Invest in air purifiers, especially for homes in urban areas like Guwahati. Additionally, keep indoor plants like peace lilies and areca palms to naturally improve air quality.

4. Strengthen Your Lungs
Engage in breathing exercises and yoga to improve lung function. Pranayama and other deep-breathing techniques can help mitigate the effects of air pollution.

5. Advocate for Change
Support initiatives to reduce air pollution in your city. Encourage the use of public transport, carpooling, and cycling to minimize vehicular emissions.

Government Initiatives to Combat Air Pollution in the Northeast

The government has taken several steps to address air pollution in the region:

  • Implementation of the National Clean Air Programme (NCAP) in cities like Guwahati and Shillong.
  • Promoting cleaner fuels like LPG and electric vehicles.
  • Introducing stricter emission norms for industries.
  • Increasing green cover through afforestation projects.

Why Raising Awareness is Crucial

One of the biggest challenges in the fight against air pollution is the lack of awareness among the general public. People need to understand the connection between air quality and their lung health to take preventive measures.

Final Thoughts

Air pollution is a growing threat to lung health in Northeast India. While the region has natural advantages, urbanization and industrialization are increasing the risk of respiratory diseases. By staying informed, adopting preventive measures, and advocating for cleaner air, we can protect our lungs and ensure a healthier future for the region.
