The character of the residential development occurring at the periphery of a metropolitan area has extensive and diverse economic and social implications. The kinds and prices of housing produced, the population groups served, and the cost and problems of providing public services are all determined by the workings of the development process. An understanding of this process requires an examina...
The quality of the urban air pollution forecast critically depends on the mapping of emissions, the urban air pollution models, and the meteorological data. The quality of the meteorological data should be largely enhanced by using downscaled data from advanced numerical weather prediction models. These different topics, as well as the application of population exposure models, have traditional...
Mounting research highlights the contribution of ecosystem services provided by urban forests to quality of life in cities, yet these services are rarely explicitly considered in environmental policy targets. We quantify regulating services provided by urban forests and evaluate their contribution to comply with policy targets of air quality and climate change mitigation in the municipality of ...

life style and life expectancy of inhabitants have been affected by the increase of particulate matter 10 micrometers or less in diameter (pm10) in cities and this is why maximum pm10 concentrations have received extensive attention. an early notice system for pm10 concentrations necessitates an accurate forecasting of the pollutant. in the current study an artificial neural network was used t...
the air quality in shiraz was assessed based on a one-week passive sampling campaign.during the first week of the summer 2003, about 400 passive samplers were used in groups of two andthree, so that 187 sampling stations covered all of shiraz. pollutant gases including so2, no2 and btx(benzene, toluene and xylene) were sampled by diffusive sampling tubes. collected samples wereanalyzed and poll...

Road dust and vehicle exhaust are the main sources of air pollution in cities, especially in recent years with the quantity of vehicles and transportation construction continuously soaring; the hazy weather has been a dominant urban pollution form which is widely concerned by the Chinese society. By establishing a relationship model between traffic and land use, then applying analytic hierarchy...
With the acceleration of urbanization and industrialization, urban air pollution has become a serious threat to the health of urban residents. In this study, to investigate health hazards caused by air pollution for urban residents, concentrations of main air pollutants and annual coal consumption amounts during the period from 2000 to 2013 were analyzed. Our results showed that economic losses...
IN T R O D U C T IO N In recent years there has been a growing concern about the rapidly deteriorating environment in the urban areas of this country in terms of air, water, and noise pollution. Automobile transportation has been found to be a significant factor in the deterioration of the urban environment, particularly in regard to air pollution. In general, con sidering the total tonnage of...
