We studied the impact of the odd–even traffic rule (implemented in Delhi during 1–15 January 2016) on primary traffic emissions using measurements of 13 volatile organic compounds, carbon monoxide, carbon dioxide and methane at a strategic arterial road in Delhi (28.57N, 77.11E, 220 m amsl). Whole air samples (n = 27) were collected during the odd–even rule active (OA) and inactive (OI) days, and analysed at the IISER Mohali Atmospheric Chemistry Facility.

The improvement has been attributed to the action taken on the ground to control pollution.

Delhi and its surrounding region’s air quality is showing the first signs of improvement, but the air is not even close to being called clean yet – says an assessment report released by the Environment Pollution (Prevention and Control) Authority (EPCA).

A gap in emission inventories of urban volatile organic compound (VOC) sources, which contribute to regional ozone and aerosol burdens, has increased as transportation emissions in the United States and Europe have declined rapidly. A detailed mass balance demonstrates that the use of volatile chemical products (VCPs)—including pesticides, coatings, printing inks, adhesives, cleaning agents, and personal care products—now constitutes half of fossil fuel VOC emissions in industrialized cities.

Airpocalypse-II, a Greenpeace India report , analyses PM10 annual average recorded for 280 cities which have 630 million, or 53% citizens of the country’s total population. A massive part of the population, 580 million (47%) of the population are living in areas where no air quality data is available.
