If the average PM 2.5 reading for the day is 50 ug/m3, what is the equivalent color coding in the DENR Air Quality Index of 2021?YellowOrangeRedPurpleMaroon

The Department of Environment and Natural Resources (DENR) in the Philippines uses a color-coded Air Quality Index (AQI) to represent the level of pollution in the air. The AQI is based on the measurement of particulate matter (PM2.5) in the air, among other pollutants.

Here is the color coding for PM2.5 according to the DENR AQI:

• Good (0-50 ug/m3) - Green
• Fair (51-100 ug/m3) - Yellow
• Unhealthy for Sensitive Groups (101-150 ug/m3) - Orange
• Unhealthy (151-200 ug/m3) - Red
• Very Unhealthy (201-300 ug/m3) - Purple
• Hazardous (301 and above) - Maroon

Given that the average PM 2.5 reading for the day is 50 ug/m3, the equivalent color coding in the DENR Air Quality Index of 2021 would be Green.
