AQI is the abbreviation for Air Quality Index, which is a numerical indicator used to measure and quantify the quality of air in a specific area. It is a standardized system developed to provide a general assessment of the air pollution levels and its impact on human health.
The AQI takes into account various pollutants, such as particulate matter (PM), sulfur dioxide, nitrogen dioxide, carbon monoxide, and ozone, that are considered harmful to human health and the environment. Each pollutant is measured and assigned a specific numerical value, which is then converted into a corresponding index value. The index ranges from 0 to 500, with higher values indicating poorer air quality.
The index is divided into several categories or levels, including good, moderate, unhealthy for sensitive groups, unhealthy, very unhealthy, and hazardous. These categories help individuals understand the air quality level and take necessary precautions or actions to protect their health and well-being.
The AQI is often used by government agencies, environmental organizations, and the public to monitor air pollution levels, issue relevant warnings or advisories, and implement appropriate measures to improve air quality. Additionally, it serves as a tool for comparing air quality conditions between different regions or countries and promoting environmental awareness and concern for air pollution-related health issues.
