  "account": "Thick smog enveloped Delhi on Wednesday as the national capital's winter pollution worsened a week before Diwali, a festival where firecrackers typically exacerbate the haze. The city's air quality index hit 379 at 10 a.m., nearing the \"very poor\" threshold set by India's Central Pollution Control Board. Fine particulate matter levels, which can infiltrate lungs and bloodstream, averaged 277, more than 18 times the World Health Organization's 24-hour recommended limit. This marks a stark contrast to last month's record clean air quality index of 166, the best October in eight years. The deterioration is due to unusually heavy rain, which washed away pollutants and improved airflow, and the usual winter phenomenon of pollutants being trapped by falling temperatures and weak winds. Every winter, Delhi's air turns toxic from emissions of vehicles, industry, construction, waste burning, and agricultural fires, causing schools and businesses to adjust operations, straining public health, and reducing productivity in one of the world's largest urban economies. Authorities have attempted to preempt the issue this year with a formal schedule of restrictions, which took effect on November 1. These measures prohibit older commercial vehicles and construction dust, limit people working from offices, and double parking charges. The regional air-quality regulator also implemented similar emergency restrictions. However, Sunil Dahiya, a climate research analyst, emphasizes that \"having a plan alone doesn't guarantee clean air; implementation remains a concern.\" The measures do not cover the broader area around the capital, which contributes to emissions, and crop burning adds to the \"already elevated pollution load.\" Delhi's microscopic pollutants, linked to cancer, originate from a mix of local and regional sources. Secondary particles, formed as emissions from all sources combine, make up 27% of winter pollution, according to India's Environment Ministry. Transport is the primary source, followed by biomass burning, including crops in neighboring states. Crop fires in nearby Punjab and Haryana have decreased by over 90% since 2021, but a model from India's Institute of Tropical Meteorology predicts their contribution to pollution will rise from under 9% on November 2 to over 20% by November 5. Despite this, environmentalists argue that Delhi's air remains unhealthy for much of the year, with authorities treating it as an episodic problem rather than an ongoing issue. Manoj Kumar, an analyst at the Centre for Research on Energy and Clean Air, notes that \"concern spikes when air turns severe and visibility falls, but less attention is given to the root causes of Delhi's consistently poor air quality.\"",
