Project will be on display at IIT-Delhi’s Open House

Nearly 60% of U.S. children live in counties with PM2.5 concentrations above air quality standards. Understanding the relationship between ambient air pollution exposure and health outcomes informs actions to reduce exposure and disease risk.

Since at least the 1980s, many farmers in northwest India have switched to mechanized combine harvesting to boost efficiency. This harvesting technique leaves abundant crop residue on the fields, which farmers typically burn to prepare their fields for subsequent planting. A key question is to what extent the large quantity of smoke emitted by these fires contributes to the already severe pollution in Delhi and across other parts of the heavily populated Indo-Gangetic Plain located downwind of the fires.

Order of the Supreme Court of India in the matter of M. C. Mehta Vs Union of India & Others dated 26/03/2018 regarding Comprehensive Action Plan for air pollution control and supplementary report on the comprehensive action plan with timelines.

The Ministry of Petroleum and Natural Gas on behalf of Union of India has stated on affidavit that BS VI will be available in the National Capital Territory of Delhi in all retail outlets with effect from 01.04.2018.

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.

GURUGRAM: The concentration of PM2.5 rose by about 20% on Sunday over Saturday, as fog continued to engulf the city.
