Key Concepts
Air Quality Index (AQI) ek aisa measure hai jo hawa ki quality ko assess karta hai. Yeh kuch pramukh pollutants par adharit hai:
| Pollutant Type | Standard Level (µg/m³) | Current Level (Bhopal, as an example) |
|---|---|---|
| PM2.5 | 10 | 151 |
| PM10 | 20 | 90 |
| SO₂ | 40 | Data unavailable |

Jitna zyada AQI level hai, utna hi kharab vayu ghatna hoti hai.
Common Misconceptions
- "AQI sirf dikhane ke liye hai": Zaroori hai samajhna ki AQI serious health risks dikhata hai, isliye ignore nahi karna chahiye.
- "Sirf dusht dinon mein AQI kharab hota hai": AQI har din badalta hai, aur kuch shehron mein ye summer ke dauran bhi kharab ho sakta hai.
- "Indoor air quality hamesha achi hoti hai": Ghar ke andar bhi pollutants hote hain, jise hum ignore nahi kar sakte.
