Most people living in European cities are exposed to poor air quality. Latest estimates by the European Environment Agency (EEA), show that fine particulate matter continues to cause the premature death of more than 400 000 Europeans annually. Road transport, agriculture, power plants, industry and households are the biggest emitters …
Exposure to fine particles is measured using metrics such as mass concentration (MC), number concentration (NC) and surface area concentration (SAC). This study aims to find correlation between the three metrics in outdoor environments of a city – city periphery, city centre and on-road. Simultaneous real-time mass, number and surface …
The Survey, “A Hazy View” posed a wide range of questions on the subject of air pollution awareness, perceptions and attitudes across 11 Indian cities – Delhi, Mumbai, Kanpur, Patna, Ahmedabad, Bangalore, Chennai, Gwalior, Kolkata, Varanasi and Lucknow. Nationally, the respondents tend to come from an educated background and are …
This document is a summary of a report, published by Greenpeace Germany, bringing together research generated from many studies demonstrating there are short-term and long-term health problems associated with exposure to nitrogen dioxide (NO2) and nitric oxide (NO). Studies have shown there are both short and long term health problems …
Indians could live four years longer on average, if India is able to reduce air pollution to comply with the World Health Organisation’s standards, according to the Air Quality-Life Index (AQLI) tool developed by the Energy Policy Institute at The University of Chicago (EPIC). In Delhi, which was for two …
The Government of India along with the various State and Local Governments is implementing several flagship Urban Missions. An overarching goal of the various missions and schemes is to make Indian cities more ‘Liveable’. The Ministry of Urban Development (MoUD) has developed a set of ‘Liveability Standards in Cities’ to …
Nowadays, most of the research on air pollution and its adverse effects on public health in China has focused on megacities and heavily-polluted regions. Fewer studies have focused on cities that are slightly polluted. Shenzhen used to have a favorable air environment, but its air quality has deteriorated gradually as …
This paper reviews the effectiveness of traffic management strategies (TMS) for mitigating emissions, ambient concentrations, human exposure, and health effects of traffic-related air pollution in urban areas. The objective is to summarize the evidence base for a range of moderate-scale strategies broadly relevant to municipal and regional government decision-making.
Epidemiology studies have shown that ambient concentrations of ozone and fine particulate matter (PM2.5) are associated with increased emergency department (ED) visits and hospital admissions (HAs) for asthma. The objective of the study was to evaluate the impact of outdoor pollen, respiratory infections, and socioeconomic status (SES) on the associations …
The study was carried out during the months of April-May, 2017 to assess the status of air quality by monitoring and assessment of some selected air pollutants namely Respirable Suspended Particulate Matter (RSPM or PM10), Fine particles (PM2.5), Sulphur Dioxide (SO2), Oxides of Nitrogen (NOx) and trace metals-Lead (Pb) and …
The action plan proposes an Integrated Urban Air Quality Management Framework to keep check on air quality of the Kathmandu Valley, a separate strategy on assessment of impact of air pollution on environment, health and economy, and recommendations for hospitals, industries and brick kilns to reduce waste and pollution. Similarly, …
This paper aims to inform the next phase of PROCONVE for LD vehicles by assessing important components of PROCONVE L6 and their relative strengths and weaknesses compared with similar programs in the United States and the European Union.

Question raised in Rajya Sabha on Air quality of cities, 10/04/2017. Cities can be ranked on the basis of different criteria pollutants with different results. On the basis of data monitored during 2015, higher levels of Particulate Matters (PM10) were observed in Ghaziabad, Allahabad, Bareilly, Jharia, Delhi, Ranchi, Kanpur, Ferozabad, …
Urban road infrastructure is crucial in determining air pollution. Yet, little is known about the roles played by road width vs. road length. This paper attempts to fill this gap by estimating the effects of road infrastructure on 10-micron particulate matter (PM10) using city-level data from the People’s Republic of …
Question raised in Rajya Sabha on Exceeding level of PM2.5, 27/03/2017. Out of the 56 cites monitored for PM 2.5 by Central Pollution Control Board, the data for the year 2015 indicates that PM 2.5 levels have exceeded permissible limits in Delhi, Bangalore, Bhopal, Gwalior, Singrauli, Angul, Balasore, Rourkela, Sambalpur, …
Question raised in Rajya Sabha on Permissible PM10 concentration, 27/03/2017. World Health Organization (WHO) has published ‘WHO Air quality guidelines for particulate matter, ozone, nitrogen dioxide and sulphur dioxide’ during the year 2005. The guidelines are intended for reference by countries to provide appropriate targets for a broad range of …
