Union also directed agencies to be on "maximum" alert and ensure all necessary measures to contain sources of dust.

The 24-hour average concentration (rolling) of PM10 was 1,400 microgrammes per cubic metre (ug/m3), more than three times above the severe level, said Gufran Beig, a at the Centre-run System of Air Quality and Weather Forecasting and Research institute (SAFAR). The severe level begins at 430 ug/m3.

"The pollution caused due to dust storm was expected to settle but the wind speed reduced yesterday, causing the dust that entered to get trapped in the atmosphere leading to prolonging of pollution," Beig said.

According to the CPCB, the air quality index (AQI) - a measurement of the concentration of toxic particulate matter in the air - at several places in remained over 500.

The PM10 level (presence of particles with diameter less than 10mm) was at 756 in Delhi-and 785 in Delhi, leading to hazy conditions.

The PM2.5 level (presence of particles with diameter less than 2.5 mm) worsened and became severe from very poor level in the past 24 hours in Delhi-at 268 and Delhi at 277.

"Today even the PM2.5 level has gone to severe from very poor. It happened because of the reduced wind speed has led to accumulation of smaller particles and increasing the PM2.5 level," Beig said. An AQI between 0-50 is considered good, 51-100 satisfactory, 101-200 moderate, 201-300 poor, 301-400 very poor, and 401-500 severe.
