considering rapid growth and migration, higher accumulation of communities along with the high number of shopping trips in mega cities such as tehran brings environmental consequences like excessive amounts of energy use, air pollution and massive urban congestions in all urban trips ending to shopping areas. the present study has been performed in tehran, capital of iran in 2009-2010. with the...

Air pollution is a major problem in Calcutta. In this study, exfoliated sputum cytology of the exposed population was done in order to get an insight into the response of the lungs to air pollutants at the individual level. 468 residents from Calcutta and 60 from Sunderban islands, where ambient air pollution is negligible, were studied. Results showed remarkable increase in alveolar macrophage...

This paper examines the utility of the air pollution Model (TAPM) in simulating meteorology and dispersion of PM10 and wind data in order to assess The Impacts of Wind Variability Function on Urban Heat Island for the day of 25, November, 2012 in Karaj city that experienced severe degradation in air quality. Drawing, Skew-T diagrams, maps of surface pressure (500hp), omega (850hp) and atmosp...

Despite the progress made in controlling local air pollution, urban areas show increasing signs of environmental stress and air quality is one of the major concerns. The findings of several studies provide evidence that the shape of a city and the land use distribution determine the location of emission sources and the pattern of urban traffic, affecting urban air quality. This work focuses on ...

Household air pollution is a major cause of ill health, but few solutions have been effective to date. While many quantitative studies have been conducted, few have explored the lived experiences and perceptions of women who do the cooking, and as a result are those most exposed to household air pollution. In this study, we worked with groups of home cooks, and sought to use art as a means of e...

Environmental concerns often figure prominently in opinion polls. But do election outcomes actually affect the environment? I test the influence of the party in power on urban air pollution in 13 Canadian cities. The government’s political stripe is not reliably associated with positive or negative effects on air pollution. Provincial parties on both the right and the left are associated with e...

Recent results suggest that adverse health effects of air pollution exist at levels of pollutants around or even below air quality standards set by national and international institutions. Furthermore, there are indications that air pollution effects on health may be partly determined by specific mixtures of air pollutants and may be altered by other environmental, behavioral, and social patter...

Lichens are good bio-indicators of air pollution, but in most tropical countries there are few studies on the subject; however, in the city of San José, Costa Rica, the relationship between air pollution and lichens has been studied for decades. In this article we evaluate the hypothesis that air pollution is lower where the wind enters the urban area (Northeast) and higher where it exits San J...

BACKGROUND China has become an aging society, and the mental health problem of the elderly is increasingly becoming prominent. This paper aimed to analyze the effect of air pollution and rural-urban difference on mental health of the elderly in China. METHODS Using the data from the China Health and Retirement Longitudinal Survey (CHARLS, 2013), after controlling the social demography variabl...

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...
