Cities interact with the atmosphere over a wide range of scales from the large-scale processes, which have a direct impact on global climate change, to smaller scales, ranging from the conurbation itself to individual buildings. The review presented in this paper analyzes some of the ways in which cities influence atmospheric thermodynamics and airborne pollutant transport. We present the main ...

THE incidence of bronchitis is uncommonly high in Britain, especially in urban areas during winter; and it has been conjectured that air pollution is at least partly responsible. In this paper I report a correlation between bronchitis mortality and the acidity of urban precipitation. The mortality-rates for bronchitis were calculated from the Registrar General’s annual statistical reviews for t...

This contribution regards three fundamental aspects of the urban pollution, sources, diffusion and chemical composition with relative speciation, pointing out the anthropogenic activities and their relationship with the environmental sustainability. The chemical parameters ruled by laws (conventional pollutants) are evidenced together with other species not ruled (no conventional pollutants) bu...

The regional atmospheric chemistry and climate model REMOTE has been used to conduct numerical simulations of the atmosphere during the catastrophic Indonesian fires of 1997. These simulations represent one possible scenario of the event, utilizing the RETRO wildland fire emission database. Emissions from the fires dominate the atmospheric concentrations of O(3), CO, NO(2), and SO(2) creating m...

Atmospheric contamination has deteriorated the health of plants and animals all over the globe. In particular, pollutants such as benzene(C6H6) has accelerated the rate of cancer among human beings. Therefore, accurate evaluation of the pollutant in the atmosphere is necessary by traffic supervision in urban areas. To reduce atmospheric contamination, an effective mobile strategy planning must ...

The Dutch cities Utrecht and Wijk bij Duurstede were founded by the Romans around 50 B.C. and the village Fijnaart and Graft-De Rijp around 1600 A.D. The soils of these villages are polluted with Pb (up to ~5000 mg/kg). Lead isotope ratios were used to trace the sources of Pb pollution in the urban soils. In ~75% of the urban soils the source of the Pb pollution was a mixture of glazed potsherd...

A study was carried out to investigate the effects of meteorological conditions on atmospheric pollutant concentrations in a complex area. In general serious pollution episodes in the urban and suburban environment are not directly caused by sudden increases in the emission of pollutants but results from unfavorable meteorological conditions, These unfavorable conditions may reduce the ability ...

Urban areas confront with increases in air pollution because of increasing urbanization, expanding the use of vehicles and development of economic activities. In this research carbon monoxide concentration as a pollutant analyzed and modeled within highways in Tehran. In this regards factors affecting the concentration of atmospheric pollutants analyzed on the basis of geometric, atmospheric an...
