Delhiites working hard but still a long way to go: Kejriwal on pollution

Chief Minister Arvind Kejriwal on Tuesday said the results of efforts made by Delhi residents to curb pollution in the city are encouraging but there is still a long way to go. His remarks came a day after Diwali when the air quality in the national capital was recorded in the 'very poor' category. The situation, however, was relatively better than previous years due to favourable meteorological conditions which diluted the effect of many residents flouting a firecracker ban and stubble burning. Delhi's air quality index (AQI) stood at 326 at 8 am. "Delhiites are working hard in the field of pollution. There have been very encouraging results but there is still a long way to go. We will make Delhi the best city in the world," Kejriwal said in a tweet in Hindi.

Despite ban, firecrackers burst in several parts of Delhi on Diwali

Firecrackers were burst by people in many parts of Delhi on Diwali night, flouting the ban imposed on it by the city government. Delhi Environment Minister Gopal Rai last week had said bursting of firecrackers on Diwali in the national capital will attract a jail term up to six months and a fine of Rs 200. Despite legal deterrent in place to discourage people from doing so, by dusk, residents in many neighborhoods, including some areas in south Delhi and northwest Delhi, had started bursting crackers. Even high-intensity firecrackers could be heard going off on ground, or mid-air. Diwali is being celebrated across the country on Monday. Bursting of firecrackers on this auspicious day is an old tradition, but authorities in the city had said the decision to restrict it was taken after considering environmental concerns and health hazards associated with it. Delhi's air quality turned "very poor" on Monday amid an increase in stubble burning, bursting of firecrackers and moderately .

Stubble burning significant contributor to Delhi's unbreathable air: Report

As the air quality in the national capital exceeds the National Ambient Air Quality Standards (NAAQS) during the winters, stubble burning remains a significant contributor to Delhi's unbreathable air in October and November, a research study by the Centre for Research on Energy and Clean Air (CREA) said. It further said the causes behind Delhi's unbreathable air include a lack of emission control technologies in major sources of pollution, vehicular emissions, and episodic events of stubble burning, making the city's air quality extremely hazardous. "With the rains between 5 and 11 October giving Delhiites a brief respite from air pollution, the city's ambient air quality has deteriorated significantly since then and will continue to do so with winter fast approaching, the study said. It said the same or even higher pollution levels are expected across other cities and rural areas nearby Delhi, including Gurgaon, Ghaziabad, Noida, Faridabad, Panipat, Ambala, Amritsar and ...
