Delhi Air Quality Improves Slightly, AQI Falls to 169

As winter comes closer, Delhi’s air usually gets worse. But on Sunday morning (October 12), the city saw a small improvement. The Air Quality Index (AQI) was 169, which is in the moderately polluted range. This is lower than 193 recorded at 5 a.m. on Saturday.

Still, the AQI has been rising compared to 129 on Friday morning and 91 on Thursday, showing that pollution is increasing slowly.

Weather update:
The India Meteorological Department (IMD) predicts that temperatures in Delhi will stay between 30°C and 32°C during the day and 18°C and 19°C at night. Temperatures have been steady in Delhi-NCR for the past few days.

About AQI:
The AQI scale is divided into six levels: Good (0–50), Satisfactory (51–100), Moderately Polluted (101–200), Poor (201–300), Very Poor (301–400), and Severe (401–500). Higher numbers mean the air is harder to breathe.

AQI is measured by checking several pollutants, especially PM2.5. These are tiny particles that can go deep into the lungs and are harmful to health.

The World Health Organization (WHO) says that breathing in PM2.5 can cause heart problems, lung cancer, and long-term lung diseases like COPD.
