The Air Quality Index: What You Need to Know

Do you know what you're breathing? The Air Quality Index (AQI) is a measure of how polluted the air is and how it may affect your health.

The AQI is calculated based on the levels of five pollutants: ground-level ozone, particulate matter, carbon monoxide, sulfur dioxide, and nitrogen dioxide.

AQI values below 50 are considered good, while values over 300 are hazardous. Higher AQI values indicate a higher risk of health problems, particularly for sensitive groups.

The AQI is based on a scale developed by the U.S. EPA. Each pollutant has a different AQI scale, and the highest value is used as the overall AQI for a given location.

Improving air quality requires a collective effort. Here are some practical tips to make a difference:

use public transportation, plant trees, use energy-efficient appliances, reduce meat consumption, avoid single-use plastic products,

support clean energy initiatives, use natural cleaning products, properly dispose of hazardous waste, and support environmental policies.

Air pollution is a significant environmental problem that affects human health and the environment. It contributes to global warming, acid rain, and smog.

Ground-level ozone is a harmful pollutant that forms when nitrogen oxides and volatile organic compounds react to sunlight. It can cause respiratory problems and worsen asthma symptoms.

Particulate matter is a mixture of solid and liquid particles that can cause respiratory and cardiovascular problems, including heart attacks, strokes, and lung cancer.

Carbon monoxide is a colorless, odorless gas that can cause headaches, dizziness, and nausea. It's particularly dangerous in enclosed spaces.

Sulfur dioxide and nitrogen dioxide are both harmful gases that can cause respiratory problems and worsen asthma symptoms.

The AQI is an essential tool for understanding air pollution (air quality) and its impact on our health.

By taking steps to reduce our carbon footprint and improve air quality, we can create a healthier and more sustainable future.
