Characterization of ozone precursor volatile organic compounds in urban atmospheres and around the petrochemical industry in the Tarragona region

This paper reports the results of an assessment of volatile organic compound (VOCs) levels in ambient air in samples collected at urban and industrial sites in southern Catalonia, which is home to one of the most important petrochemical complexes in southern Europe. This study contains data from a total of 192 samples collected in 2007, from May to October, at six air pollution measurement stations within the area of influence of several chemical and petrochemical industrial plants. The ambient air concentrations of a group of 65 VOCs, some of them ozone precursors, were determined by active sampling into sorbent tubes, thermal desorption and gas chromatography-mass spectrometry. At the same time, several meteorological parameters were also recorded, and levels of NO, NO₂ and O₃ measured by the automatic stations, have been included in the study as well. Ambient air profiles of the different areas were studied, and the ozone formation dependent on VOCs and NO₂ levels was also analysed, taking into account the photochemical ozone creation potential (POCP) for different groups of VOCs.     

Integrating conservation planning and landuse planning in urban landscapes

The rapid growth of cities around the world is now seen as a major contributor to global biodiversity loss and many governments include biodiversity conservation as an explicit policy goal. To help prevent further loss of biodiversity, there is an urgent need for more strategic approaches to conservation planning in urban environments based on a scientific understanding of landscape patterns, species requirements and development pressures. In this study, we demonstrate the use of new conservation planning tools to better integrate information on threatened species into landuse planning. We present a case study in the Greater Melbourne area that utilises the Zonation conservation planning tool with data for 30 threatened fauna species. We perform a multi-species spatial prioritisation that incorporates species-specific connectivity requirements and demonstrate the use of this information in a number of landuse planning contexts. First, we quantitatively assess the differences between Melbourne's current conservation areas with the locations prioritised by Zonation and determine priority areas for their extension. We then show how the prioritisation can be used in decisions regarding Melbourne's Urban Growth Boundary and in rezoning land for development. Finally, we demonstrate how the prioritisation can be used to identify areas of conservation significance within individual developments that account for the wider landscape context. These results demonstrate how conservation planning tools can be better integrated into the different stages of landuse planning for future urban growth.     

Detection of ventilation paths using high-resolution roughness parameter mapping in a large urban area

In this study, an urban roughness mapping method is presented on the example of a large study area in Szeged, Hungary, as an example. With this roughness mapping procedure, the potential ventilation paths of the city can be located. Our calculations of the roughness parameters are based on a 3D building database; however, this new approach using the lot area polygons provides more detailed results than other recent studies. The detected ventilation paths could play a significant role in the development of the urban heat island circulation and result in the reduction of air pollution in the central parts of the city. Based on our results, we can mark out the areas where the city government should keep the advantages of the ventilation paths considering the human comfort aspects of the urban climate, thus providing important input data for urban planning procedures.
