All life form on this planet depends on clean air. Air quality not only affects human health but also components of environment such as water, soil, and forests, which are the vital resources for human development. Urbanization is a process of relative growth in a country’s urban population accompanied by an even faster increase in the economic, political, and cultural importance of cities rela...

Urban air pollution is an important environmental factor that is effecting a large portion of urban dwellers in developing economies. Due to the limitations of dose and impact nature, direct measurement of negative implications of urban air pollution is difficult and WHO has developed indirect methods such as Environmental Burden of Disease. However, in this study to measure the economic costs ...

In response to the facts that some Asian developing countries were experiencing the fastest rate of industrialisation and urbanisation, several international initiatives called for a better and ‘sustainable’ urban management. Development of management tools including strategic environmental assessment (SEA), life cycle assessment (LCA), cost benefit analysis (CBA), and environmental managemen...

Urban air quality, and its variability in space and time, is a critical issue for human exposure and health related studies. In this work, we investigated the intra-urban distribution of SO2, NOx, NO2, Benzene, Toluene, and Xylenes in ambient air in one of the world’s most polluted cities, Lanzhou, China. Measurements were contemporarily carried out at forty locations in four seasonal campaigns...

abstract urban expansion, pollution augmentation, and extention of major industrial activities in metropolitan areas impacted local climates of major cities. transforming big cities into heat islands is one of the most prominent results of such a micro-climate change. in this study, variation of precipitation, temperature and some other important climatic parameters including relative humidity,...

air pollution is one of the most important problems in urban areas that always threaten citizen's health. photochemical smog is one of the main factors of air pollution in large cities like tehran. usually smog is not only a part of nature, but is being analyzed as an independent matter, which highly affects on the nature. it has been used as relationship between atmospheric elements such as te...

This study assessed the public's health risk awareness of urban air pollution triggered by three megacities in China, and the data are the responses from a sample size of 3868 megacity inhabitants from Shanghai, Nanchang and Wuhan. Descriptive analyses were used to summarize the respondents' demographics, perceived health risks from air pollution and sources of health-related knowledge on urban...

Epidemiological studies on the effect of urban air pollution on lung cancer were surveyed. Overall, the studies from many countries point to a smoking-adjusted risk in urban areas over countryside areas that is higher by a factor of up to 1.5. The extent to which urban air pollution contributes to this excess remains unknown. Studies on diesel-exposed occupational groups show that urban air pol...

the relationship between public health and urban planning is an innovative and important issue that it has prominent position in future urban planning. in this context, adverse air quality condition and air pollutant concentrations higher than the permitted limit set by the world health organization is considered as a threat to the health of citizens in big cities. according to result of air po...
