Smog cover over Delhi-NCR; air quality severe amid unhelpful meteorological conditions
New Delhi(PTI): A layer of smog shrouded Delhi-NCR on Thursday and partially blotted out the sun on Chhath Puja as the air quality slipped back into the severe zone with unfavourable meteorological conditions aiding accumulation of pollutants, authorities said.
Green think tank Centre for Science and Environment (CSE) said the ongoing smog episode is a public health emergency.
"This requires urgent emergency action on key combustion sources (vehicles, industry, waste burning) and dust sources (construction and roads) to prevent further trapping of pollution when there is no wind to blow this away," said Anumita Roychowdhury, executive director, research and advocacy, CSE.
At 10 am, Delhi recorded an Air Quality Index (AQI) of 407. Thirty-three of the 39 air quality monitoring stations in the national capital recorded air pollution levels in the severe category.
The 24-hour average AQI was 372 on Wednesday.
Ghaziabad (454), Greater Noida (404) and Noida (426) also recorded severe air quality at 10 am.
An AQI 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".
An official from the India Meteorological Department (IMD) said shallow fog and low temperatures in the morning -- Delhi recorded the season's lowest temperature of 12.6 degrees Celsius on Thursday -- trapped pollutants close to the ground and calm winds led to stagnant conditions.
Visibility levels at the Indira Gandhi International Airport and the Safdarjung Airport dropped to 600-800 metres, he added.
The CSE said the current severe smog episode in Delhi-NCR is expected to last for two more days.
It also said the average daily contribution of smoke from farm fires from the middle of October to November 8 was the lowest in four years.
"Compared to the first smog episode of the previous four years, the current smog has matched the duration of the first smog of 2018 and 2020 season -- both lasted six days. If conditions do not improve, it might overtake the 2019 smog that lasted eight days," the CSE said.
The longer duration of this year's smog despite relatively windier local conditions might be due to a lack of pollution control measures in the city, the green think tank said.
On an average, the contribution of smoke to Delhi's daily PM2.5 from the middle of October to November 8 was the lowest in the last four years.
"So far, it has recorded an average of 12 per cent (farm fire share) per day in contrast to 17 per cent per day in 2020, 14 per cent per day in 2019 and 16 per cent per day in 2018 (as reported by SAFAR)," the CSE said.
The share of farm fires in Delhi's pollution rose to 48 per cent on Sunday, the highest since November 5, 2018, when it was recorded at 58 per cent.
Last year, the share of stubble burning in Delhi's pollution had peaked at 42 per cent on November 5. In 2019, crop residue burning accounted for 44 per cent of Delhi's PM2.5 pollution on November 1.

Gruha Jyothi, drought in state contribute to 11.35 pc increase in power consumption in 2023-24
Bengaluru: The overall power consumption on domestic basis across Karnataka has increased by 11.35 per cent between August 2023 and July 2024, with all electricity supply companies (escoms), except the Bengaluru Electricity Supply Company (BESCOM), recording a rise of 10 to 19.75 per cent this year.
The power use has increased by 3.76 per cent within BESCOM limits, which includes not only Bengaluru Urban and Rural districts but also other districts like Ramanagar, Tumakuru, Kolar, Chikkaballapur, Davanagere and Chitradurga in 2023-24, reports Deccan Herald.
The increase is being attributed to the extension in drought and high-temperature days in the state as well as to the implementation of the Gruha Jyothi scheme by the state government, as the number of beneficiaries has increased during said period by 7.13 per cent.
In contrast to the hike witnessed in the state this year, Karnataka had recorded a 4.64 per cent increase in power consumption in 2022-2023, as households had used 16,089 million units (MUs) in 2023-24, which was 1,263 MUs higher than the number of units consumed in 2022-23.
While the six escoms in Karnataka provides electricity to around 1.98 crore households in total, more than 1.69 crore users have enrolled for Gruha Jyothi. Of these, 1.6 crore users have availed of the benefits of the scheme.
The government had given a 10 per cent buffer on the average power consumption of 2022-23, for the households to receive zero-electricity bill, with Energy Department sources informing that the state government had predicted the power consumption in Karnataka to rise by 10 per cent at most, as compared to 2022-23.
The state government had, however, not allocated additional funds in the budget for the scheme, although it has been clearing escom dues regularly, a senior officer has said.
Another senior officer confirmed that drought and high temperatures have contributed to the increased household power consumption across the state. However with good rainfall this year, the power consumption could be expected to return to its average level, the officer added.
Low rainfall in the summer of 2023 had reduced the power supply in the state, forcing escoms to also reduce supply to irrigation pumpsets. Several areas in the state also used to report scheduled load shedding. There have been instances where the government has purchased power from private players and national grid at Rs 7.42 to Rs 10 per unit during peak season, said the officer.
The state currently depends on renewable energy sources, including hydro, wind and solar powers, to meet 63 per cent of its requirements.
