Traffic is one of the main sources of air pollution in metropolitan areas. With development of transportation system, inappropriate vehicle production, and the use of low-quality fuels, increased pollution in these areas is inevitable. The current study tries to determine PM2.5, PM10, NO2, and CO emission dispersion, caused by traffic, using CALINE4 software. Ac...

Air quality in greater Algiers, in Algeria was assessed analyzing aerosol particulate matter (PM10 and PM2.5) at a site influenced by heavy road traffic. Particulate matters were collected using a Gent sampler to characterize the atmospheric aerosol of Algiers. An Energy dispersive X ray spectrometer (EDXRF) was used to determine the heavy metal concentrations in the PM2.5 and PM10 size fractio...

Background & Aims of the Study: Particulate matters less than 10 microns can absorb into your lungs and reacting with the moisture and enter the circulatory system directly through the airways. The aim of this study is to assess Behavior PM 10 data in different seasons and Determination effects on human health in Ahvaz city during 2013. Materials & Methods: Data Particulate matters less than 10...

To develop urban stormwater management effectively, characterization of urban runoff pollution between dissolved and particulate phases was studied by 12 rainfall events monitored for five typical urban catchments. The average event mean concentration (AEMC) of runoff pollutants in different phases was evaluated. The AEMC values of runoff pollutants in different phases from urban roads were hig...

Urban areas which are situated at the intersection of Alpine valleys are submitted to complex atmospheric flow patterns with significant impact on air quality. Local dynamics develop systems of slope and valley winds which interact ones with the others. Pollutants evolve according to chemical reactions homogeneously as gases and heterogeneously with particulate matters .There is a growing conce...

introduction: air pollution is one of the problems of the recent century caused by vehicles, industries and other urban activities. the city of yazd faces air pollution due to its high population, vehicular traffic and industrial places around the city. one of the important parameters of air pollution is suspended air particles that have harmful effects on the health of people, plants and objec...

In urban areas, emissions of air pollutants by anthropogenic processes such as traffic, industry, power plants and domestic heating systems are the main sources of pollution (Fenger, 1999). The massive growth in road traffic and in the use of fossil fuels during the last decades has changed the composition of urban air, increasing the frequency of pollution episodes and the number of cities exp...
