Air Quality Index reports in the national capital indicated that PM 2.5 was moderate and PM 10 particles were in severe categories on Saturday but haze continued to loom over the national capital and its adjoining areas for the sixth consecutive day.
In Delhi's Lodhi Road area, the PM 2.5 particles level was at the 169 mark, while PM 10 pollutant level was at 500.
Strong-anti cyclonic winds, blowing from Rajasthan, have been singled out as the reason behind the worsening air quality.
Based on these numbers, air quality has improved considerably since yesterday, when the PM10 level was over 700 in most of the areas in Delhi-NCR areas, leading to hazy conditions and limiting visibility.
The Air Quality Index of RK Puram and Anand Vihar were recorded 948 and 999 respectively.

As per the Air Quality Index level - from 0-50 is considered 'good', 51-100 is 'satisfactory', 101-200 is 'moderate', 201-300 is 'poor', 301-400 is 'very poor', and 401 and above is 'severe' or 'hazardous'.
The Central Pollution Control Board or CPCB had on Thursday asked for all construction activities to be stopped temporarily as part of emergency measures to curb dust pollution. Over 170 challans were issued and 12 buildings were sealed yesterday in south Delhi by the area's civic body on those found violating the order.
The civic body is said to have intensified mechanical road sweeping of streets as part of the measures. People have also been advised to stay indoors.
