Understanding AQI, air pollution in Hyderabad
The AQI is a standardized system for measuring air quality. Here’s a quick breakdown of AQI levels and their health implications:
- 0-50: Good
- 50-100: Moderate
- 100-200: Poor
- 200-300: Unhealthy
- 300-400: Severe
- 400-500+: Hazardous
Air pollution in Hyderabad largely results from two main types of particulate matter: PM10 and PM2.5.
PM10: These particles, typically originating from dust and smoke, are around 10 micrometres in diameter. Hyderabad’s current PM10 level stands at 70 micrograms per cubic meter.
PM2.5: These are smaller particles, measuring 2.5 micrometres or less, which are even more harmful as they can penetrate deep into the lungs. The PM2.5 level in Hyderabad is 30 micrograms per cubic meter.
