Browse By

The recent survey says that, the rise in pollutants in the air of Delhi is mainly due to dust storms from Rajasthan, the Environment Ministry said after air quality in Delhi deteriorated beyond “severe” level on Wednesday and predicted that dusty conditions were likely to prevail over the next three days.

The deterioration in the air quality of the state is due to the ground level dust storm in western India which increased coarser particles in the air- as per the report submitted by Central Pollution Control Board (CPCB).

The report says that the pollution this season is different from that of the last year. In November, 2017 both PM2.5 and PM10 level had spiked leading to serious health hazard. The current condition is due to the increase in level of coarse particles in the air.

The ministry speaks “The high pollution levels during this time of the year in Delhi are unusual and primarily due to dust storms from Rajasthan. Rajasthan is facing extremely drought, with high temperatures and wind speeds”. The ministry alerted the major construction agencies and companies, including Municipal Boards and Delhi Pollution Control Committee (DPCC) to ensure water sprinkling and issued appropriate instructions regarding the matter.


According to the India Meteorological Department (IMD), the current surface winds in Delhi are in the range of 5-6 m/sec and wind direction is West to South West, which is likely to continue over the next three days.

“CPCB convened an urgent meeting of the Task Force regarding the implementation of Graded Response Action Plan (GRAP) today and issued necessary directions to contain local dust sources. The Task Force has also recommended that public should avoid prolonged exposure,” the Ministry said.

Therefore, it is expected that dusty conditions will prevail in Delhi over the next three days. Major construction agencies, municipal corporations and Delhi Pollution Control Committee (DPCC) have been alerted to ensure water sprinkling, as required,” it said.
