NEPSE this week

The article presents a standard scale for measuring air quality, categorizing different levels of pollution. The Air Quality Index (AQI) is broken down into distinct ranges, providing a clear understanding of air conditions.

The scale begins with 'Good' for AQI readings between 0 and 50. This indicates minimal health risk. As the AQI increases, the categories become more concerning.

Readings from 51 to 100 are classified as 'Moderate,' suggesting that some individuals may experience health effects. Those with sensitive groups might feel the effects. The next level, 'Unhealthy for Sensitive Groups,' covers AQI values from 101 to 150. This means that while the general public is less affected, members of sensitive groups may experience health issues.

Further increasing pollution levels are marked as 'Unhealthy,' ranging from 151 to 200. At this stage, everyone may begin to experience health effects. Finally, AQI values from 201 to 300 are labeled 'Very Unhealthy,' indicating significant health risks for all individuals. The article also notes a 'Hazardous' category above 300, though specific numerical ranges for this extreme level are not detailed in the provided text.
