Study of the influence of road traffic emissions on air quality in sensitive areas of the Bucharest city, using Breeze Aermod software

Abstract Road traffic is one of the main causes pollution in big cities due to a large number vehicles and crowded intersections. Also, lack green spaces topography land can cause accumulation pollutants at local level. Considering increasing concern regarding negative impact air on health inhabitants cities, present paper aims investigate level areas two educational units located near some boulevards city Bucharest. To carry out work, quality was analyzed by in-situ monitoring CO, PM 10 , NO 2 indicators atmospheric that could come from road traffic. Also were estimate contribution nearest sources total concentrations measured equipment. Although more emission estimated first area, than second still case area higher, this aspect complexity terrain, higher buildings surrounding sources, vegetation.
