Assessment of Exposure to Air Pollution from Road Traffic : Use of Air Dispersion Model Caline4 at a Fine Scale in Cracow

摘要: This article deals with the road traffic air pollution modeling which is also part of a main multidisciplinary study health risk characterization untitled: "Air generated by and childhood asthma in Cracow". Cracow, city declared as UNESCO World Heritage Site, constitutes relevant urban area to insofar strong anthropogenic source pollution. The final aim establish Cracow relationship between quality development among children. We have chosen dispersion model CALINE4 its software interface, CALROADS VIEW, estimate PM10 NO2 concentrations at 43 key intersections during period 2001-2005. recognized an international reference modeling. concentration trips historical downtown importance exchanges two downtowns (historical Nowa Huta) are causes high levels from traffic. Depending on pollutant considered (PM10, NO2) well density meteorological situations, areas exposure their potential effects exposed population quite different time space. results show that: 1) Only reach residential because (Avg: 66.8 m SD: ą 48.5, max: 284 m) less extensive than those 125.4 64.4, 381 m); 2) Extension these proportionally related extended unsymmetrical way around roads depending cases determined both Pasquill-Gifford classification wind directions. According our methodology, validation estimated shows that they been overwhelmingly validated.
