Delhi records worst air quality of season as haze engulfs national capital: authorities
New Delhi, Oct 28 : Delhi recorded its worst air quality of this season on Sunday as a thick haze engulfed the national capital which continued to grapple with deteriorating air quality.
The overall Air Quality Index of the national capital was recorded at 381 which falls in the very poor category, the highest of this season and just points below severe pollution level, according to data by the Central Pollution Control Board.
An AQI between 0 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".
Twelve pollution monitoring stations located in various parts of Delhi recorded severe air quality while 20 stations recorded very poor air quality, according to data by the Central Pollution Control Board.
Authorities attribute the dip in air quality to localised factors like construction dust, vehicular pollution as well as regional factors like pollution due stubble burning from Punjab and Haryana.
A thick haze due to smog engulfed the national capital which recorded the worst air quality of this season, authorities said.
A CPCB-led task force has recommended to Supreme Court appointed Environment Pollution Control Authority implementation of stringent measures from November 1 to 10, predicting further deterioration in the air quality ahead of Diwali.
Some of these recommendations include shut down of coal and biomass factories, intensification of inspection by transport department to check polluting vehicles and control traffic congestion in Delhi NCR during November 1-10.
The task force also issued an advisory to the public, asking them to avoid outdoor strenuous activities and minimise use of private vehicles.
The task force also warned that at beginning of November the situation may get further deteriorated on account of localized emissions during festival and regional contribution due to stubble burning.
The PM2.5 (presence of particles in the air with a diameter of less than 2.5 micrometres) was recorded at 225, the highest of this season. The PM2.5, also called "fine particulates," can be a matter of more serious health concern than PM10.
The PM10 level (presence of particles in the air with a diameter of less than 10 micrometres) in Delhi stood at 418, according to the CPCB data.
SAFAR also issued a heath advisory, urging people with heart or lung disease, older adults and children to avoid prolonged or heavy exertion.
It also recommended people to go for shorter walks instead of jogs, keeping windows closed and wearing masks while stepping outside.

LPG bookings close to normal, but situation continues to be worrisome
New Delhi (PTI): Bookings for domestic LPG refills are approaching pre-war normal levels, signalling a gradual return to normalcy, but concerns persist as supply restrictions on commercial consumers, including hotels, remain in place due to ongoing disruptions in input supplies caused by the West Asia conflict.
Over 33 crore domestic LPG consumers had, on average, booked about 55 lakh cylinders daily before the February 28 military strikes by the US and Israel on Iran. The escalation triggered sweeping retaliation from Tehran, effectively shutting the Strait of Hormuz - a critical shipping corridor used by major Gulf producers such as Saudi Arabia, Qatar and the UAE to export crude oil, gas and LPG to key markets including India.
The shutdown of the Strait of Hormuz blocked India's access to almost 60 per cent of its LPG, leading to curtailment of supplies to commercial users and triggering panic buying by domestic users, which peaked to 87.7 lakh on March 13.
Bookings have since fallen to 56-57 lakh on March 18, said Sujata Sharma, Joint Secretary, Ministry of Petroleum and Natural Gas.
"Panic booking is coming down," she said, adding that the government continues to prioritise the supply of available LPG to domestic households.
However, "LPG (supply) situation remains worrisome but there is no dry out at any LPG distributor," she said.
Commercial users are getting just a fifth of their requirement.
Sharma said domestic LPG production has increased by over 40 per cent in the last two weeks and the three public sector oil marketing companies have been making normal, pre-war levels of daily deliveries of LPG refills.
"Our supply has not dipped. Some days the supply has been higher (than pre-war times). On March 18, 54.91 lakh LPG cylinders were delivered against a booking of over 56 lakh," she said.
Oil companies are operating extra shifts to keep LPG deliveries in pace with the bookings. They delivered 62.5 lakh cylinders on March 13 and 60 lakh on March 14 - the peak two days of panic bookings.
LPG supplies are under close monitoring amid the prevailing geopolitical tensions, with no dry-outs reported at distributorships and domestic cylinder deliveries continuing uninterrupted, she said.
Online bookings have risen sharply to 94 per cent, while Delivery Authentication Code (a unique OTP that is sent to registered mobile numbers of actual users to ensure LPG is being delivered to correct customers) coverage has expanded to 83 per cent.
In addition, customers near a city gas network are being encouraged to shift to piped natural gas - a convenient alternative to LPG as the fuel continuously travels through pipes to household kitchens without the botheration of refill bookings.
"In the last two weeks, 1.25 lakh new domestic, commercial and industrial connections have been issued," she said.
Raids and inspections to stop black marketing continue with seizure of cylinders as well as FIRs in several states.
The Union government on March 18 wrote to all state governments asking them to take all steps to prevent black marketing and hoarding while taking stringent actions against violators.
Besides, alternate fuels such as kerosene are being promoted, she said adding commercial LPG stocks have been placed with states for using them as per their priority list.
