Understanding Air Quality: Comparing Global Standards and Protection Strategies

In an era where air quality is a pressing concern, it’s crucial to understand how to interpret air quality data effectively. With over 6,000 cities in 117 countries now monitoring air quality, many weather mobile apps also provide air quality information. However, these numbers can be confusing without proper context.

Interpreting Air Quality Index (AQI): A Numerical Guide

To simplify air quality levels, many countries use an Air Quality Index (AQI) — a numerical scale where higher numbers indicate worse air quality. These indexes often come with color codes to show whether the air is clean, unhealthy, etc.

Global Variations in Air Quality Standards

It’s important to note, however, that different countries have varying air quality standards. For instance, India’s daily limit for fine particles (PM 2.5) is more than 1.5 times higher than Thailand’s limit and four times higher than the World Health Organization (WHO) standards.

This disparity means that countries calculate AQIs differently, making the numbers non-comparable. Sometimes, private companies using stricter standards may report AQIs that diverge from those calculated by national regulators.

Protecting Yourself from Air Pollution

The primary goal when air quality is poor is to minimize exposure, often by staying indoors or wearing a mask. However, staying indoors is not always feasible, especially for those who must live or work outside.

Danny Djarum, an air quality researcher at the World Resources Institute, an environmental advocacy group, notes, “They can’t really afford not going out.”

Pakaphol Asavakomolnant, an office worker in Bangkok, underscores this by wearing a mask daily and opting not to ride a motorbike to work. He recounted, “I get a sore throat when I come to work in the morning and I forget to wear a mask.”

Battling Indoor Air Pollution

Another important consideration is indoor air pollution, which can result from common household activities such as cooking or burning incense sticks. Awareness of these sources is crucial for maintaining good air quality within your home.

Conclusion: Stay Informed, Stay Protected

While air quality monitoring and AQI systems provide valuable information, it’s essential to understand the variations between different countries’ standards. Implementing protective measures, both indoors and outdoors, is vital to safeguarding your health.
