Ghaziabad and Noida most polluted cities in country on Monday
Ghaziabad city on Monday had the highest air quality index (AQI) reading of 384 (under the ‘very poor’ category) in the country as per the Central Pollution Control Board (CPCB) data.
Neighbouring Noida stood second, also under the ‘very poor’ category, with an AQI reading of 347 on Monday.
According to officials, the prevailing dust-raising winds, cloudy weather and mild shower conditions will continue for another three or four days. The officials attributed these conditions to the ongoing western disturbance, which is likely to be followed by another similar disturbance.
They said that this would lead to the pollution continuing at similar levels. “The prevailing conditions are due to the ongoing western disturbance. This will affect areas in Delhi-NCR, south Haryana and parts of western Uttar Pradesh, including Mathura and Agra.
“The rise in pollution in Delhi-NCR is due to dust-raising winds blowing in from Rajasthan. The areas that will receive light rain may see a reduction in pollution,” Kuldeep Srivastava, the head of Regional Weather Forecasting Centre, New Delhi, said.
He said the next western disturbance is likely to arrive on May 15.
“This is likely to result in a dust storm, thunderstorm and lightening. There is also a possibility of a hailstorm. As a result of the prevailing weather conditions, the temperature, which had shot up to 42-43 degrees Celsius, will come down to about 38-39 degrees Celsius. In another three or four days, the temperature will come down further by one or two degrees Celsius,” he added.
An AQI reading between zero and 50 is considered “good”, 51 and 100 “satisfactory”, 101 and 200 “moderate”, 201 and 300 “poor”, 301 and 400 “very poor”, and 401 and 500 “severe”.
Apart from Ghaziabad and Noida topping the list of most polluted cities on May 13, other areas of Loni Dehat in Ghaziabad recorded an AQI of 371, while Greater Noida recorded an AQI of 289.
Ghaziabad’s AQI on May 9 had shot to 401 under the ‘severe’ category, reduced to 331 on May 11, and again risen to 382 on May 12. Ghaziabad had topped the list of the most polluted cities on a number of occasions during the last winter as well .
Likewise, the AQI for Noida also increased to 372 on May 9 and came down to 292 on May 11. On Sunday, May 12, it again rose to 338.
“We will revert to pollution control measures such as water sprinkling,” Ritu Maheshwari, district magistrate (Ghaziabad), said.
