.=====================================
Delhi's pollution is caused by a combination of local emissions and external factors, including vehicular and industrial pollution, dust from construction, burning of waste and crop residue in neighboring states, and meteorological conditions that trap pollutants. During winter, low wind speeds and temperature inversions prevent pollutants from dispersing, worsening the air quality.
Primary causes
Vehicular emissions: The high volume of vehicles, particularly diesel-powered ones, is a major source of pollutants like PM2.5 and PM10.
Industrial emissions: Industries contribute pollutants such as sulfur dioxide and nitrogen oxides.
Construction and road dust: Dust from ongoing construction projects and unpaved roads makes up a significant portion of PM2.5 in the city.
Stubble burning: During certain seasons, smoke from farmers burning crop residue in surrounding states drifts into Delhi, drastically increasing pollution levels.
Waste burning: Open burning of garbage and waste is a significant contributor.
Contributing factors
Meteorological conditions: During winter, geographic factors like Delhi's location in the Indo-Gangetic Plain, combined with low wind speeds and temperature inversions, trap pollutants near the ground, preventing them from dissipating.
Household emissions: The use of solid fuels for cooking and heating in low-income households releases harmful particulate matter.
Firecrackers: Celebrations involving firecrackers add significantly to the pollution load, particularly during festivals like Diwali.
