Noise and Air Quality Assessment in an Urban Tissue. Case study: Ştefan cel Mare Street, Bucharest. The improvement of the air quality in urban ecosystems constitutes an essential objective of the European Union’s environmental politics, considering that 52% of the urban population is exposed to over the maximum admissible limits of air polluting concentrations. The paper aims to assess the impact of environmental degradation sources on airborne dust and noise level in the residential areas around Ştefan cel Mare Street. To achieve this objective, 16 sampling points were chosen and measurements of equivalent sound level (Leq) and particulate matter (PM) concentrations were realized between May 25 and June 12, 2009. The values were correlated with the characteristics of functional areas (oxygen-generating surfaces, built areas, road network), of air quality pollution sources (structure and intensity of road traffic, condition of buildings, number of evacuation chimneys) and of the receivers of environmental problems (population, sensitive functional areas, vegetation). The study emphasizes that the area crossed by Ştefan cel Mare Street is characterised by affected living conditions, as high levels of noise and PM concentrations have a notable influence over 7,350 inhabitants and three hospitals of national importance. Therefore, reduction of pollution level in this area through fountains, pollutants filtration systems from the ventilation systems and a series of measures on the environmental degradation sources (interdiction of heavy traffic, rehabilitation of buildings) are necessary.

Keywords: air quality, environmental degradation sources, noise pollution, particulate matter, oxygen-generating surfaces, urban ecosystem, Bucharest, Romania.
