The capital's AQI remains 'very poor' with conditions unlikely to improve

If you’ve been checking the news or simply stepping outside in the capital city, you may have noticed a recurring concern — the air quality is alarmingly bad. Day after day, reports show that the Air Quality Index (AQI) remains stuck in the ‘very poor’ category, with no signs of improvement anytime soon. This isn't just a random inconvenience; it's something that could have serious implications for your health and daily life. So, what does ‘very poor’ AQI mean for you, and why does the situation seem to be getting worse instead of better?

Let’s break it down.

What is AQI and Why Should You Care?

Before diving into the reasons behind the capital's worsening air quality, let’s first understand what AQI means. The AQI, or Air Quality Index, is a number that represents the quality of air in a specific area. The higher the number, the worse the air quality. This index is based on a range of pollutants, including particulate matter (PM2.5 and PM10), ozone, carbon monoxide, sulfur dioxide, and nitrogen dioxide, all of which have harmful effects on human health.

The AQI scale runs from 0 to 500, with each level corresponding to different health advisories. Anything below 50 is considered ‘good,’ but as the number climbs, the risks to your health become more significant. For example:

• 0-50: Good – The air is clean and poses little or no risk.
• 51-100: Moderate – Acceptable air quality, but may affect sensitive individuals.
• 101-150: Unhealthy for sensitive groups – Children, elderly, and people with respiratory issues could be affected.
• 151-200: Unhealthy – Everyone may begin to experience adverse health effects.
• 201-300: Very Unhealthy – Health alert for the entire population.
• 301-500: Hazardous – Emergency conditions where everyone is at risk.

The capital's current AQI level sits in the ‘very poor’ category, which means that the air is significantly polluted and could pose serious health risks, particularly for vulnerable individuals like children, the elderly, and those with pre-existing conditions such as asthma or heart disease.

Why Is the Capital’s AQI So Poor?

So, why is the air in the capital so unhealthy right now? Unfortunately, there’s no single reason. A combination of factors has contributed to the deteriorating air quality, and many of them are beyond individual control. Here are some key contributors:

1. Vehicular Emissions

One of the biggest culprits behind the rising AQI is vehicular pollution. With the population growing rapidly, more cars are on the roads than ever before. Exhaust fumes from cars, trucks, and buses contain harmful pollutants such as nitrogen dioxide, carbon monoxide, and tiny particulate matter (PM2.5), which are small enough to penetrate deep into your lungs and even enter your bloodstream. The problem is exacerbated during rush hours when traffic congestion increases.

2. Industrial Pollution

Another major factor is industrial activity. Factories and power plants release large quantities of pollutants, including sulfur dioxide and volatile organic compounds (VOCs), into the atmosphere. In some cases, these pollutants mix with other airborne substances to form smog, which further worsens air quality.

3. Burning of Crop Residue

In certain parts of the world, especially in agricultural regions, the practice of burning leftover crop stubble is common. This smoke, when carried by the wind, can settle over cities, leading to a spike in particulate matter levels. This phenomenon is particularly noticeable during the harvest season, when air quality typically plummets.

4. Weather Conditions

Believe it or not, the weather also plays a significant role in air quality. During the colder months, the air becomes denser and pollutants can get trapped closer to the ground in a process known as ‘temperature inversion.’ This makes it harder for pollutants to disperse, leading to a noticeable rise in AQI. This is why winter often brings a more severe pollution problem in many urban centers, including the capital.

What Are the Health Impacts?

The most immediate concern with ‘very poor’ AQI levels is the impact on health. Poor air quality is a well-documented cause of respiratory issues and can exacerbate conditions like asthma, bronchitis, and even cardiovascular diseases. Long-term exposure to air pollution can lead to chronic respiratory problems, lung cancer, and a shorter life expectancy.

Even healthy people aren’t immune. Prolonged exposure to high levels of pollution can cause irritation in the eyes, nose, and throat, fatigue, and difficulty breathing. In extreme cases, poor air quality can even trigger heart attacks.

What Can You Do About It?

While the thought of dealing with persistently poor air quality can be overwhelming, there are steps you can take to protect yourself and reduce your exposure to harmful pollutants:

1. Monitor AQI Regularly

Check local AQI reports daily, either through apps or news sources. If the levels are particularly bad, avoid going outside for prolonged periods, especially during peak pollution times like early morning or late afternoon.

2. Wear Protective Masks

If you must venture outside, consider wearing an N95 mask. Unlike regular cloth masks, these are specifically designed to filter out fine particulate matter like PM2.5, which can otherwise easily enter your lungs.

3. Use Air Purifiers

Indoor air can be just as polluted as outdoor air, especially if you live near a busy road or industrial area. Using an air purifier at home can help filter out pollutants and provide cleaner air for you and your family to breathe.

4. Keep Windows Closed

On days when the AQI is particularly bad, it’s a good idea to keep your windows closed to prevent polluted air from entering your home. This is especially important during the night, as pollutants tend to settle closer to the ground in the cooler hours.

5. Limit Outdoor Exercise

While exercise is important for maintaining good health, you should avoid outdoor workouts when air quality is poor. Exercising increases your breathing rate, which means you’ll be inhaling more pollutants. If possible, exercise indoors until the AQI improves.

6. Advocate for Change

Reducing air pollution isn’t something that can be achieved overnight, but every bit of awareness and advocacy helps. Support policies that push for stricter emission standards, cleaner transportation options, and renewable energy sources. Collective action is crucial for long-term improvement in air quality.

The Road Ahead: Will Things Improve?

In the short term, the forecast for air quality improvement doesn’t look promising. The capital city is likely to continue grappling with high pollution levels for the foreseeable future due to the combined impact of emissions, industrial activity, and weather patterns. However, long-term solutions are within reach if governments, industries, and individuals work together.

Efforts to promote electric vehicles, impose stricter regulations on industrial emissions, and transition to renewable energy sources are already underway in many parts of the world. While these changes will take time, they are essential steps toward reducing air pollution and improving the health of urban populations.
