This latest CPCB report provides details of the monitoring study conducted to measure Ozone levels, VOCs including carbonyls in ambient air in the city of Kolkata. It also includes recommendations for control of VOCs releases. Volatile Organic Compounds or VOCs play an important role in tropospheric chemistry byaffecting the OH …
Fireworks display during festive celebrations can cause acute short term air pollution. Deepawali –the festival of light– is celebrated in India, every year during October or November with great fireworks display. Concentration of air pollutants such as SPM (suspended particulate matter), PM10, PM2.5, SO2 y NO2 were monitored for six …
One hundred and forty days before Delhi hosts the Commonwealth Games, Chief Minister Sheila Dikshit, on May 15, called a meeting to discuss ways to control air pollution in the city. Officials from various state departments and activists were invited to the meet. Air pollution in the city is increasing …
One hundred and forty days before Delhi hosts the Commonwealth Games, Chief Minister Sheila Dikshit, on May 15, called a meeting to discuss ways to control air pollution in the city. Officials from various state departments and activists were invited to the meet. Air pollution in the city is increasing …
Epidemiologic and health impact studies of fine particulate matter (PM2.5) are limited by the lack of monitoring data, especially in developing countries. Satellite observations offer potentially valuable global information about PM2.5 concentrations. Van Donkelaar et al. mapped global ground-level PM2.5 concentrations using total-column aerosol optical depth (AOD) from the Moderate …
Acute exposure to ambient air pollution has been associated with cardiac outcomes, often within hours of exposure. The incidence of effects within the population depends on a number of factors, including genetic differences. Baja et al. examined the associations of air pollutants with heart-rate
Although commuters are exposed to high air pollution concentrations, little quantitative information currently exists on differences in exposure from different modes of transport, routes, and fuel types. Zuurbier et al. (p. 783) measured exposures to particle number counts (PNCs) and particulate matter ? 2.5
Biomass burning produces emission of a whole variety of trace gases, which is a matter of concern due to its effects on atmospheric chemistry and the climate system. We report emission attributes of meji2 burning, a festive biomass burning ritual, in Assam and the neighbouring states of northeast India. (Correspondence)
Urban air pollution is reportedly responsible for nearly 1 million annual deaths worldwide. The burden of disease from air pollutant exposure may be greatest in growing urban populations in the developing world, but risk assessment is often impeded by lack of exposure information at the local level in many urban …
This study estimates the morbidity costs of a reduction in air pollution in Dhaka, the capital of Bangladesh, using the Cost-of-Illness (COI) approach. COI is defined as the sum of lost earnings due to workdays lost or restricted activity days and the mitigation expenditure borne due to illness. The data …
Aerosols: Integrating an understanding of source-receptor relationships with climate forcing on regional scales a paper presented by Chandra Venkataraman at National climate research conference, IIT Delhi, March 5-6, 2010.
In urban areas roads surrounded by high rise buildings cause trapping of respirable suspended particulate matter, PM2.5 in the lower regions. Under these situations it is very desirable to know the location of the trapped pollutants in order to find ways to mitigate their health effects. The present study focuses …
In order to assess the role of meteorology as a diffusing or non-diffusing agent, this paper presents a 20 year analysis of the effects of meteorology on air pollution and has considered Delhi for pilot analysis. The study will be extended to 10 more cities in 2010.
Motor vehicles are a significant source of urban air pollution and are increasingly important contributors of anthropogenic carbon dioxide and other greenhouse gases. As awareness of the potential health effects of air pollutants has grown, many countries have implemented more stringent emissions controls and made steady progress in reducing the …
The impact of air pollution on the human health and the ecosystem is increasingly been linked to the growing transport sector. A major intervention that Delhi is counting on is the extension of the metro rail system, to shift the motorized transport trends to the metro rail. The expected level …
In this report, the third in this Series on health and climate change, we assess the changes in particle air pollution emissions and consequent effects on health that are likely to result from greenhouse-gas mitigation measures in the electricity generation sector in the European Union (EU), China, and India. We …
Calcutta began the week as a polluted city but will end it as a critically polluted city. The new standards for air quality announced by the environment ministry on Wednesday have pushed Calcutta firmly into the hall of shame, with the toxic count of at least two major pollutants being …
