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.

Businessman lured by FB friend, attacked for extortion in K'taka; 4 held
Madikeri (Karnataka) (PTI): Four people were arrested for allegedly assaulting, illegally confining and attempting to extort money from a 39-year-old businessman who was lured through a honeytrap set up on social media, police said on Monday.
The accused have been identified as Rachana, Malati, Darshan and Ravi.
Police said efforts are underway to nab the remaining suspects involved in the incident, which occurred on December 12 in Madikeri, the district headquarters of Kodagu.
According to the complaint, the victim, a resident of Maddur taluk in Mandya district, was befriended by a woman identified as Rachana through Facebook, who later sought financial assistance and received Rs 5,000 from him via PhonePe on November 28.
When he asked her to return the money, the woman allegedly asked him to travel to Mysuru or Kushalnagar, promising to meet him.
The police said the woman later called the victim to Madikeri on December 12 and took him to a house near the market area, where they spent some time and consumed alcohol in the evening.

Later that night, citing an emergency, the woman left the house. After her departure, three men allegedly broke into the house and attacked the victim, assaulting him with a stick and the handle of a sword, causing injuries to his face, mouth, chest and leg, the FIR stated.
The complainant alleged that he was forcibly confined, stripped and a nude video of him was recorded. The accused also allegedly threatened him with a toy gun, demanding Rs 50 lakh and warning that the video would be uploaded on social media if the money was not paid.
Police said the victim was held captive and somehow managed to escape in the early hours of December 13. However, after he escaped, the accused allegedly attempted to kidnap him in an autorickshaw, an incident that was captured on CCTV cameras.
Based on his complaint at the Madikeri Town police station, a case was registered under Sections 310(2) (dacoity), 127(2) (wrongful confinement), 118(1) (voluntarily causing hurt or grievous hurt by dangerous weapons or means) and 3(5) (common intention) of the Bharatiya Nyaya Sanhita, a senior police officer said.
“Four accused, including two women, have been arrested. Efforts are on to nab two more absconding accused. Further investigation is on,” he added.
