The bottom-up traffic emission model EMISENS is used to calculate hourly black carbon (BC) and nitrogen oxides (NOx) emission rates on an average workday in Maribor (Slovenia), using emission factors that were previously determined with the on-road chasing measurements in Slovenia. From modeled NOx emission rates and in-situ NOx measurements we empirically determined the hourly dispersion of traffic emissions and applied it to model BC concentrations using BC emission rates.

Replacing high volumes of cars with high volumes of cyclists and pedestrians makes roads safer and the air cleaner, finds a Greenpeace Germany report ranking 13 European cities on sustainable transport, mobility and air quality. Safe roads and clean air go hand-in-hand.

More than 80% of people living in urban areas that monitor air pollution are exposed to air quality levels that exceed the World Health Organization (WHO) limits. While all regions of the world are affected, populations in low-income cities are the most impacted.
 

GURUGRAM: The air quality in the city deteriorated as the PM2.5 level increased three times on Thursday as compared to Wednesday.

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.
