NEPSE this week

Understanding air quality is crucial for public health, and Nepal utilizes an Air Quality Index (AQI) to communicate pollution levels. The Kathmandu Post provides a clear breakdown of these levels, helping residents interpret daily conditions.

The AQI scale categorizes air pollution into several distinct bands. Readings from 0 to 50 are considered 'Good,' indicating minimal risk. As pollution increases, the 'Moderate' range (51-100) suggests that some individuals may experience health effects. This is followed by 'Unhealthy for Sensitive Groups' between 101 and 150, where members of sensitive groups may experience health effects, and the general public is less likely to be affected. The 'Unhealthy' category, from 151 to 200, signifies that everyone may begin to experience health effects.

When AQI levels reach 201 to 300, the air quality is deemed 'Very Unhealthy,' posing significant health risks to all individuals. The most severe category, 'Hazardous,' applies to AQI readings above 300, indicating dangerous levels of pollution that require immediate health precautions. This information is vital for citizens to make informed decisions about outdoor activities and health protection.
