Particulate pollution has important consequences for human health, and is an issue of global concern. Outdoor air pollution has become a cause for alarm in India in particular because recent data suggest that ambient pollution levels in Indian cities are some of the highest in the world. We study the number of particles between 0.5μm and 2.5μm indoors while using affordable air purifiers in the...

Hebei is one of the most air polluted provinces in China. According to the Ministry of Environmental Protection (MEP) for the severe fog-haze month of Jan. 2013, seven of the top ten most polluted cities in China are located in Hebei Province. In this study, the air pollution history and status of the Hebei Province are reviewed and discussed, using the governmental published Air Pollution Inde...

swelling urban populations and increasing number of industry and especially automobiles in and around cities have resulted in adverse effect on human health. one of the most important things regarding air pollution in these days is that the number of motor vehicles has increased, and the resulting problems of new types of air pollution on large scale need to be emphasized in large cities.the gr...

environmental economist with Science Applications International Corporation (SAIC). Ash and Fetter are joint co-authors. We thank Jim Boyce and John Stranlund for their invaluable guidance, and we are deeply grateful to Nick Bouwes and Steven Hassur of the Environmental Protection Agency who have painstakingly developed and graciously provided us with access to the Risk Screening Environmental ...

This research paper is an attempt towards analyzing real time air pollution data collected by PAQS sensor devices from some key locations in Bangalore. Air pollution in most of the metropolitan cities in India is turning out to be a major threat to our environment and hazardous to our health. Many infections and diseases related to lungs and throat are caused by the polluted air we breathe. The...

Growing cities, featuring more people with higher incomes who live and work in the suburbs and commute by private vehicle, should be a recipe for increased air pollution. Instead, California’s major polluted urban areas have experienced sharp improvements in air quality. Technological advance has helped to “green” the average vehicle. Such quality effects have offset the rising quantity of mile...

OBJECTIVE Pathophysiological mechanisms and pathways linking cardiovascular mortality and morbidity with air pollution were recently hypothesized. The present study evaluated association between air pollution and changes in heart rate variability as a marker of cardiac autonomic function in healthy individuals, and also determined the frequency of cardiac arrhythmias and QT interval changes on ...

People who live in cities with dirty air have blacker lungs than people who live in rural areas with less air pollution. This is because, although particulates larger than 10 microm are filtered out when inhaled air passes through the nose, smaller particulates reach the lower airways. The particulates that reach the alveoli (the terminal air pockets of the lungs) stay there permanently. This a...

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 a result of development in recent years. So far, no systematic investigations...

Development of strategies to control urban air pollution is a complex and multi-disciplinary process involving a wide range of scientists with different expertise and interests. This paper presents an integrated assessment methodological scheme for the evaluation of air pollution control measures that are put forward in order to reduce sufficiently air pollution levels in urban areas. Forming l...
