The air quality in Delhi is getting serious


Air quality in Delhi deteriorated on Monday evening, as pollution levels again increased due to unfavorable meteorological conditions, even as a task group for pollution control, the CPCB recommended heavy vehicles to enter the city and carry out construction work only between 6 am and 6 pm. .

The EPCA, designated by the Supreme Court, also allowed entry of only those vehicles into the city that were stuck in Delhi, predicting that the situation would get out of control when the owners of more than 1,000 trucks became "aggressive", while claiming they would be relieved of this duty. from the toll or the environmental compensation fee (ECC) from 23:00 on November 12 to 7 on the 13th of November.

They said that by alleviating ECC tolls, trucks can move without any stop, which will reduce congestion and reduce pollution. The Environmental Pollution Control Office (EPCA), however, stated that "no new trucks" would be allowed to enter the capital of the country due to the deterioration of air quality.


The ban on the entry of heavy vehicles was imposed from November 8 to November 11, but was later extended by a day appointed by the Supreme Court agency for recommendations of the Task Force of the Central Pollution Control Commission (CPCB), which reviews the air quality in the capital.

According to the CPCB, the general air quality index (AQI) in the capital was recorded at 406, which belongs to the heavy category.

The value of PM2.5 (particles in the air with a diameter of less than 2.5 microns) on Monday was recorded at 263, while PM10 (particles in air with a diameter less than 10 micrometers) was recorded at 457.

Nineteen areas in Delhi have experienced severe air quality, while 17 areas have shown very low air quality, said CPCB, adding Ghaziabad, Faridabad, Greater Noida and Noida noted serious air quality, while Gurgaon showed an improvement with AQI in the moderate category.

AQI between 0 and 50 is considered "good", 51 and 100 "satisfactory", 101 and 200 "moderate", 201 and 300 "weak", 301 and 400 "very weak", and 401 and 500 "serious".

Satellite images in the Centerrun system The air quality system and weather forecast (SAFAR) showed a moderate number of fires that contribute to seven percent of PM2,5 in Delhi. Authorities attribute a drop in air quality to adverse weather conditions, such as low wind speed.

SAFAR said the situation is likely to improve on Tuesday, but it will remain in a very bad category.

"The impact of stubble is still nominal due to the slow winds of transport height," he said.

EP President Bhure Lal in a letter to the joint police commissioner (traffic) said that all trucks on the border of the country's capital will be able to enter the city, but will not be asked to stop and pay tolls or environmental charges (ECC) from 23: 00 from November 12 to 7 am on November 13.

"By loosening the ECC fare, the trolleys can move without stopping, which reduces congestion and reduces pollution." The SDMC is required to issue the necessary orders not to charge the ECC or charges for this limited period, "wrote the letter.

However, he also said that "no new trucks will be allowed to enter" in the city, and the Delhi police will increase their workforce at all entry points to ensure no congestion.

"We will continue this limitation, so that large-scale lorry transport takes place on the western and eastern express roads and other roads," wrote the letter.

Meanwhile, a task team led by the CPCB on Monday declared that trucks and construction works will be allowed in Delhi only between 6 am and 6 pm to avoid a bad dispersion of pollution at night.

A task force made up of CPCB members, the Delhi Pollution Control Council and the Haryana Pollution Control Board prepared recommendations due to poor dispersion of pollution, low temperatures and high humidity at night.
