Asli Sawaal Yeh Hai
Air Quality Index (AQI) ek numerical scale hai jo hawa ki quality ko measure karta hai. Iska purpose pollution levels ko samjhane aur public health ke liye alert karna hota hai. India mein, pollution control board isko measure karta hai aur data public ke liye release karta hai.
AQI Categories Aur Indian Context
AQI ko alag-alag categories mein divide kiya gaya hai:
| AQI Value | Pollution Level | Health Effects |
|---|---|---|
| 0 - 50 | Good | Samaan hoga, kisi health impact ki zaroorat nahi hai. |
| 51 - 100 | Moderate | Some pollutants ki wajah se sensitive groups par impact. |
| 101 - 200 | Unhealthy for Sensitive Groups | Sensitive logon ko dikat ho sakti hai. |
| 201 - 300 | Unhealthy | Sab logon ke liye unhealthy. |
| 301 - 500 | Hazardous | Health warnings of emergency. |

Aaj kal, Delhi, Mumbai, aur Kolkata jaisi cities mein AQI high rehta hai, jo ki traffic, industry, aur seasonal changes ki wajah se hota hai.
Key Concepts Aur Examples
- Sources of Pollution: Factory emissions, vehicle exhaust, aur construction ke kaam se hawa ki quality kharab hoti hai.
- Seasonal Changes: Diwali ke aas-paas aur winter mein AQI generally kharab hota hai, jab ki monsoon season mein ismein improvement dekha ja sakta hai.
Common Misconceptions
- Pollution sirf urban areas mein hota hai: Yeh galat hai, rural areas bhi kabhi kabhi crop burning ya dust storms ki wajah se affected hote hain.
- AQI sirf ek day ka measurement hai: AQI daily fluctuate hota hai, lekin long-term exposure ka effect bhi health par padta hai.
