To determine the amount of air pollutants, produced by Iranian automakers, and compare it with old and retrofitted vehicles have become one of the important tools of urban management. The present research uses International Vehicle Emission (IVE) modeling software in order to verify SAIPA Co. fleet emissions, based on Euro 4 emission standard (SAIPA Co. recognized as a superior Iranian brand in...
In most countries, environmental regulation has focused on local pollution, which causes damages near the emission source, while national regulation on greenhouse gases (GHG) has been slow. In this paper, we ask whether US local air pollution regulations have had an effect on GHG emissions. On the one hand, a firm required to lower emissions of local pollutants might respond by adopting technol...
The quick growth of vehicles is due to fast urbanization in mega cities during last decades. This phenomenon has serious impacts on air quality, as emission from mobile vehicles is the major source of air pollution. As a result, any attempt to reduce the emitted air pollutants is needed. This study aims at improving the fuel quality in transporting system with particular emphasis on taxis in Te...

weather and climate have considerable influence on the concentration of air pollutants such as particles and gases. the range and concentration of these particles and gases are very dependent on prevailing weather conditions and air currents. this research concentrates on health effects of benzene, one of the air pollutants of tehran, as a major city. the concentration of benzene emission to ai...
air pollution is a major concern of new civilized world, which has a serious toxicological impact on human health and the environment. it has a number of different emission sources, but motor vehicles and industrial processes contribute the major part of air pollution.according to the world health organization, six major air pollutants include particle pollution, ground?level ozone, carbon mono...
