Want to know how AQI affects your day? Explore the truth behind this number!
In today's society, air quality has become the focus of many people's attention. People's daily plans and behaviors can be affected by the Air Quality Index (AQI). The AQI is an indicator developed by government agencies to inform the public of current air pollution levels and their potential risks to health. As air pollution levels increase, the AQI value rises, and the first groups to be affected are usually children, the elderly, and people with respiratory or cardiovascular diseases.
When AQI values are high, government agencies often advise people to reduce outdoor activities or even avoid going out altogether.
With global warming and the acceleration of industrialization, the concentration of pollutants in the atmosphere is quietly changing people's daily lives. Health advisories emerge whenever air quality deteriorates due to smog, vehicle emissions or natural disasters such as wildfires. Governments and public health organizations will not only encourage specific groups to reduce outdoor activities, but will also declare "response days" to encourage the public to voluntarily reduce emissions.
In Washington, D.C.'s air quality monitoring reports, the AQI calculation involves the concentrations of multiple pollutants and their corresponding health effects. Generally speaking, these indicators are divided into multiple levels based on the different pollutants and the degree of their impact on health. Each level is not only distinguished by color, but also comes with specific health recommendations.
When AQI reaches its peak, the use of masks and indoor air purifiers with HEPA and activated carbon filters are recommended.
Specifically, many countries have their own defined AQI systems designed to meet their own health and environmental needs. For example, Canada’s Air Quality Health Index (AQHI) and China’s Air Pollution Index both reflect each country’s monitoring and reporting of air quality.
In the United States, the Environmental Protection Agency develops an AQI that is divided into six different categories, clearly defining health risks and concentration ranges of pollutants. Because of this, the AQI is not just a set of numbers, but a barometer of the health of the local atmosphere.
People with respiratory or cardiovascular problems and sensitive groups should carefully consider whether to choose outdoor activities on days when the AQI is significantly elevated.
In addition to daily life affected by the epidemic, some cities may activate emergency plans or even order the reduction of operations of large emission sources if the AQI density is too high. This measure is not only for current health issues, but also for long-term environmental protection. Thus, every breath should be a guarantee for health.
In Delhi, India, the worst AQI value even reached 1,081, a figure that has caused global concern. The main reason is the sharp increase in fine particulate matter, which continues to threaten the health of local residents. These figures remind us that wealthy cities are not just about prosperity, but also about air quality issues that need to be taken seriously.
And in Europe, the CAQI (Common Air Quality Index) facilitates communication and comparison between countries, reflecting the complex relationship between pollution and health. This is exactly what modern society needs, and these indices convey not only numbers but also substantive impacts on behavior and policy.
As technology advances, real-time air quality data is becoming more available. More and more cities and countries are beginning to promote public health and environmental protection measures to enable citizens to make smarter choices in their daily lives to address potential air pollution risks.
We cannot control external environmental factors, but we can understand the AQI, pay attention to the health of ourselves and others, and make corresponding daily plans. This not only strengthens individual awareness of prevention, but also prompts us to discuss air quality issues on a larger platform and seek solutions. So how can we control our daily lives so that we are not bothered by air quality?
