Air pollution is becoming an urgent concern in Pakistan, as smog blankets cities, impacting lives in countless harmful ways. The World Health Organization has repeatedly raised alarms about Pakistan’s air quality, particularly in cities like Lahore and Karachi, where seasonal smog disrupts daily life and poses severe health risks. To effectively tackle smog, it’s essential to understand its causes, its effects on health, and what actions can help reduce its impact on Pakistan’s population. A nationwide healthcare emergency has been declared across most cities in Pakistan.
What is Smog?
Smog is a type of severe air pollution created when pollutants from vehicles, factories, and other sources react with sunlight. Unlike natural fog, smog contains toxic gases, particulate matter (PM), and chemicals like sulfur dioxide, nitrogen oxides, and carbon monoxide. Smog occurs in two main forms: sulfurous smog (from coal and sulfur) and photochemical smog (from vehicle emissions), both of which impact Pakistan’s air quality severely during winter.
In Pakistan, smog tends to increase between October and February. This period sees a spike in pollutants due to colder weather, industrial activity, and agricultural burning in nearby regions. Cities like Lahore and Karachi frequently top the global rankings for poor air quality during these months, raising significant concerns about public health and safety.
Why is Smog Increasing in Pakistan?
Several factors contribute to the rising levels of smog in Pakistan, including:
- Vehicle Emissions: With a growing population and urbanization, the number of vehicles on the road has surged, resulting in high levels of carbon emissions. Diesel and gasoline vehicles, especially older models, release a significant amount of nitrogen oxides, contributing heavily to smog formation.
- Industrial Emissions: Many factories and industrial sites in Pakistan operate without adequate emission controls, releasing sulfur dioxide and particulate matter that blend with other pollutants to create dense smog layers.
- Agricultural Burning: Farmers in Punjab often burn crop residue after harvests to clear their fields quickly, releasing thick clouds of smoke into the atmosphere. These practices add a considerable amount of particulate matter to the air, worsening smog conditions across the region.
- Construction Dust and Waste Burning: Dust from construction and the burning of waste materials also contributes to particulate matter in the air, further compounding the smog problem.
The Health Impacts of Smog: Equivalent to Smoking 30 Cigarettes a Day
The effects of smog on human health are both immediate and long-lasting. According to studies, smog exposure in Pakistan can reduce life expectancy by up to seven years. This figure underscores the severe threat smog poses, affecting even those who might feel that they are safe within their homes. For perspective, breathing in Pakistan’s air is akin to smoking 30 cigarettes a day in heavily polluted cities like Lahore.
The main health effects of smog exposure include:
- Respiratory Issues: Smog contains harmful particulate matter that can penetrate deep into the lungs, causing asthma, bronchitis, and other respiratory ailments. Children and the elderly are especially vulnerable to these effects.
- Heart Disease: Long-term exposure to pollutants in smog has been linked to an increased risk of cardiovascular diseases, including hypertension, heart attacks, and strokes. The particles in smog can enter the bloodstream, causing inflammation and stress on the cardiovascular system.
- Weakening the Immune System: The toxins in smog weaken the immune system, making individuals more susceptible to infections. For those already dealing with chronic illnesses, this can lead to severe complications and a higher risk of mortality.
- Mental Health Impact: Recent studies have shown that chronic exposure to smog can also affect mental health, causing stress, depression, and cognitive decline. The toxic air impacts brain function and overall well-being, adding another layer of concern for public health.
How to Combat Smog: Preventative Methods for Cleaner Air
Addressing smog requires both individual action and structural reforms to reduce emissions and improve air quality. Here are some practical ways Pakistan can work toward a healthier, smog-free environment.
1. Promoting Cleaner Transportation
Encouraging the use of public transportation, cycling, and walking can significantly reduce vehicle emissions. Expanding infrastructure for electric vehicles and implementing emission standards for vehicles could also reduce smog levels in the long term.
2. Industrial Regulation and Emission Control
The government should implement stricter regulations on factories and industrial sites, requiring the use of clean technologies and regular monitoring of emissions. This shift could significantly reduce sulfur dioxide and particulate emissions.
3. Sustainable Farming Practices
The government could introduce incentives for farmers to adopt eco-friendly practices for crop residue management. Alternatives to burning, such as mulching or plowing residues back into the soil, would not only reduce smog but also enhance soil fertility.
4. Awareness and Education
Public awareness campaigns about the dangers of smog and methods to reduce exposure are essential. Educational programs can help people understand the importance of wearing masks during high-smog days, using air purifiers, and supporting policies for cleaner air.
5. Monitoring Air Quality
People can monitor air quality using real-time apps or websites that track pollution levels. Knowing when air quality is especially poor allows individuals to take precautions, like staying indoors or wearing protective masks, particularly for children and the elderly.
6. Planting More Trees
Increasing green spaces and planting trees in urban areas can help absorb pollutants and improve air quality. Trees like neem and peepal, known for their ability to filter pollutants, are ideal for planting in high-traffic areas.
