What Does AQI Mean?
The Air Quality Index (AQI) is a standardized tool used to report daily air quality. It communicates how clean or polluted the air is, and what potential health effects might be associated with it. The AQI scale typically ranges from 0 to 500, with lower numbers indicating superior air quality:
- 0-50 (Good): Air quality is deemed satisfactory, posing minimal or no health risk.
- 51-100 (Moderate): Air quality is acceptable, though some sensitive individuals may experience minor health concerns.
- 101-150 (Unhealthy for Sensitive Groups): Individuals with respiratory or heart conditions may experience adverse health effects.
- 151-200 (Unhealthy): The general public may begin to experience health effects, with sensitive groups facing more serious impacts.
- 201-300 (Very Unhealthy): Health warnings are issued for emergency conditions, and the entire population is likely to be affected.
- 301-500 (Hazardous): Represents a severe health alert, with everyone at risk of serious health effects.
Ho Chi Minh City's AQI of 79 falls into the "Moderate" category, indicating generally acceptable air quality for most individuals.
Factors Influencing Air Quality
Air quality in bustling urban centers like Ho Chi Minh City is influenced by a combination of factors, including:
- Industrial Activities: Emissions from factories and power plants.
- Transportation: Exhaust fumes from the high volume of vehicles, particularly motorcycles.
- Construction: Dust and particulate matter generated by ongoing building projects.
- Weather Patterns: Climatic conditions can either help disperse pollutants or trap them, affecting local air quality.
- Agricultural Practices: Seasonal agricultural burning in surrounding areas can contribute to haze.
