Delhi’s October Air Quality Worst First Week Since 2023

Delhi’s air was more polluted during the first week of October than in the same period in the past two years.

Its average air-quality score was 171.

That score is called moderate under India’s air-quality scale.

The air became less clean after the monsoon ended.

Forecasters expected the air to stay in the moderate range for a few more days.

Slow winds and limited air movement can make it harder for pollution to disperse.

Officials also detected 70 crop-residue fires in four states on Wednesday.

The report gives air-quality readings for each of the first seven days of October.
