The air quality in Delhi remained beyond the “severe” level for the third day on Thursday, as authorities warned the dusty conditions are likely to prevail for another 3-4 days and advised people to avoid staying outdoors for long hours.
The air quality deteriorated because of dust storms in western India, particularly Rajasthan, which increased coarser particles in the air, the Central Pollution Control Board said
The PM10 level (presence of particles with diameter less than 10mm) was beyond severe at 796 in Delhi-NCR and 830 in Delhi particularly, leading to hazy conditions
According to the CPCB, the air quality index – a measurement of the concentration of toxic particulate matter in the air – at several places in Delhi remained beyond the 500-mark, with east Delhi’s Anand Vihar area recording a PM10 level of 929 and PM2.5 level of 301 this morning
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”
The wind blowing in the region has contributed to the spread of dust particles. According to the Met department, wind speed reaching up to 35 kmph is predicted for Thursday in Delhi. The dust-laden winds have created a haze in Delhi-NCR since Wednesday..PTI
