Air pollution and the microvasculature: A cross-sectional assessment of in vivo retinal images in the population-based multi-ethnic study of Atherosclerosis (MESA)
Long- and short-term exposures to air pollution, especially fine particulate matter (PM2.5), have been linked to cardiovascular morbidity and mortality. One hypothesized mechanism for these associations involves microvascular effects. Retinal photography provides a novel, in vivo approach to examine the association of air pollution with changes in the human microvasculature.Air quality assessment, emissions inventory and source apportionment studies for Kanpur city
Pollution control strategies for attainment of particulate standards must be able to provide convincing evidence that the relative importance of emission sources is understood and that the control programmes proposed are cost-effective and can be adopted by the community with confidence. To specifically address these issues, Central Pollution Control Board, …Size characterization of particulate matter from a kerbside in a major metropolis in India
PM10 and PM2.5 samples were collected from a kerbside at a traffic junction in a major metropolis of India during month of December 2005 and their concentrations were calculated. The Pm2.5 fraction in PM10 varied from 18.7 to 72.6%. Such a large variation was correlated with meteorological variables. The major …Energy and environmental implications of carbon emission reduction targets: Case of Kathmandu Valley, Nepal
This paper analyzes the sectoral energy consumption pattern and emissions of CO2 and local air pollutants in the Kathmandu Valley, Nepal. It also discusses the evolution of energy service demands, structure of energy supply system and emissions from various sectors under the base case scenario during 2005–2050. A long term …An estimate of the global burden of anthropogenic ozone and fine particulate matter on premature human mortality using atmospheric modeling
Ground-level concentrations of ozone (O3) and fine particulate matter [? 2.5 µm in aerodynamic diameter (PM2.5)] have increased since preindustrial times in urban and rural regions and are associated with cardiovascular and respiratory mortality. We estimated the global burden of mortality due to O3 and PM2.5 from anthropogenic emissions using …Risk-based prioritization among air pollution control strategies in the Yangtze River Delta, China
The Yangtze River Delta (YRD) is the fastest growing economic development region in China and one of the most densely populated regions in the world, with recent dramatic increases in energy consumption and atmospheric emissions. To inform air pollution control strategy design, Zhou et al. studied how different emission sectors …Global mortality attributable to aircraft cruise emissions
Aircraft emissions impact human health though degradation of air quality. The majority of previous analyses of air quality impacts from aviation have considered only landing and takeoff emissions. We show that aircraft cruise emissions impact human health over a hemispheric scale and provide the first estimate of premature mortalities attributable …Study of urban air quality in Kolkata
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 …Air pollution from fireworks during festival of lights (Deepawali) in Howrah, India - a case study
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 …Delhi's wake up call
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 …Delhi’s wake up call
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 …Global estimates of ambient fine particulate matter concentrations from satellite-based aerosol optical depth
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 …Traffic-related air pollution and QT interval: Modification by diabetes, obesity, and oxidative stress gene polymorphisms
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-rateCommuters exposure to particulate matter air pollution is affected ?by mode of transport, fuel type
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 ? 2.5Aerosol and CO emissions during meji burning
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)Within-neighborhood patterns and sources of particle pollution: ?Mobile monitoring and geographic information system analysis
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 …Morbidity costs of vehicular air pollution: examining Dhaka city in Bangladesh
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 …State of the air 2010
